Cocjh1: Seriously now sell Pro-Alloy rad

[[Image:Standard oem radiator.jpg|thumb|right|Standard OEM radiator with plastic end tanks]]
[[Image:Oem rad end tank leak.jpg|thumb|right|Drivers side plastic end tank leaking under pressure]]

The standard OEM Elise radiator is another weak point in the cooling system. Although it is lightweight, it has plastic end tanks which are prone to expanding and leaking under pressure (possible manufacture problem where the main core is bonded to the top/bottom - but no reference). This is the most common fault and the first signs of failure are drops of coolant on the windscreen, either drivers or passengers side, but catastrophic failure of the end tanks has been known.

Unfortunately you need to [[Remove the front clamshell|Remove S2 front clamshell]] before you can [[replace the radiator & cooling fans|replace the radiator]].

A upgraded radiator is pretty advisable when going for Honda/Audi/Duratec engine upgrades. Most converted cars on the original radiators seem to blow them up pretty soon after conversion.

==Aftermarket Upgrades==
There are basically three options available when it comes to after market radiators that will fit an Elise/Exige. All three are 'all aluminium' and none have the dreaded plastic end tanks. There appears to be only two manufacturers that are making these radiators. The 42mm single row is made by ??? and the 45mm twin row single pass is made by [[Pro Alloy]]. All on-line retailers sell the same radiators, they just badge them with different names to confuse you. Hopefully the following table will help when making your choice for purchase:

The radiator fitted by Lotus with the plastic end caps is a 32mm single core, single pass, manufactured by [http://www.pmagroup.co.uk/branches.php PMA Group]. The direct replacement for this radiator, maintaining the same coolant volume in the system, is in column one. Columns two and three offer greater capacity. Other variations are available but the above three will cater for 99.9% of people on road and trackdays.

The following video will help you understand some of the terms used in radiator speak, like twin rows, dual cores, triple pass etc:

===Triple Pass===
The triple pass radiators are only intended for motorsports and are '''not recommended for road use'''. The reason being there is not enough coolant flow at idle (sitting in traffic) to force the coolant through three passes of the radiator. Road users who have fitted triple-pass radiators have resulted in increased engine temps. This advice holds for heavy trackday heros that drive their cars to/from circuit; the car is still liable to be stationary in traffic.

"bespoke" denotes limited supply radiators specially created by race shops / tuners for high-performance cooling

==Indication of HGF==
Its been suggested in the past that a blown radiator can indicate imminent HGF. The header tank cap is normally the first to vent when the system is pressurised since it only requires approximately 1 bar. The radiator is designed to operate at pressures a lot higher than this and the cap acts as a fuse. However, the header tank is on the lowest pressure point of the circuit and this allows high pressure peaks on the high pressure side (which is from the engine to the rad). Therefore it would be prudent to have a petrochemical test (sniff test) performed on the coolant fluid if the radiator fails to rule out possible HGF.

{{clr}}

==Leaks==
[[Image:Oem rad end tank leak.jpg|thumb|left|Drivers side end tank leaking under pressure]]
The most common fault with the OEM radiator is cracking/spliting of the plastic end tanks. The first signs of failure are drops of coolent on the windscreen, either drivers or passengers side, but castrophic failure of the end tanks has been known.
{{clr}}

Quite often the passenger side hose is poorly connected (because it is difficult to do) and sometimes the bleed screw can leak.

The OEM radiators seem to have a problem with their manufacture where the main core is bonded to the top/bottom and leaks are all too common.

===Triple Pass===
The triple pass radiators are only intended for motorsports and are '''not recommended for road use'''. The reason being there is not enough coolant flow at idle (sitting in traffic) to force the coolant through three passes of the radiator. Road users who have fitted triple-pass radiators have resulted in increased engine temps. This advice holds for heavy trackday heros that drive their cars to/from circuit; the car is still liable to be stationary in traffic.

Cocjh1: /* OEM Radiator */

[[Image:Standard oem radiator.jpg|thumb|left|Standard OEM radiator with plastic end tanks]]
The standard OEM Elise radiator is another weak point in the cooling system. Although it is lightweight, it has plastic end tanks which are prone to expanding and leaking under pressure.

Unfortunately you need to [[Remove the front clamshell|Remove S2 front clamshell]] before you can [[replace the radiator & cooling fans|replace the radiator]].

A upgraded radiator is pretty advisable when going for Honda/Audi/Duratec engine upgrades. Most converted cars on the original radiators seem to blow them up pretty soon after conversion.

The header tank cap is normally the first to vent when the system is pressurised since it only requires approximately 1 bar. The radiator is designed to operate at pressures a lot higher than this and the cap acts as a fuse.

Therefore it would be prudent to have a petrochemical test (sniff test) performed on the coolant fluid if the radiator fails to rule out possible HGF.

==Aftermarket Upgrades==
There are basically three options available when it comes to after market radiators that will fit an Elise/Exige. All three are 'all aluminium' and none have the dreaded plastic end tanks. There appears to be only two manufacturers that are making these radiators. The 42mm single row is made by ??? and the 45mm twin row single pass is made by [[Pro Alloy]]. All on-line retailers sell the same radiators, they just badge them with different names to confuse you. Hopefully the following table will help when making your choice for purchase:

The radiator fitted by Lotus with the plastic end caps is a 32mm single core, single pass. The direct replacement for this radiator, maintaining the same coolant volume in the system, is in column one. Columns two and three offer greater capacity. Other variations are available but the above three will cater for 99.9% of people on road and trackdays.

The following video will help you understand some of the terms used in radiator speak, like twin rows, dual cores, triple pass etc:

===Triple Pass===
The triple pass radiators are only intended for motorsports and are '''not recommended for road use'''. The reason being there is not enough coolant flow at idle (sitting in traffic) to force the coolant through three passes of the radiator. Road users who have fitted triple-pass radiators have resulted in increased engine temps. This advice holds for heavy trackday heros that drive their cars to/from circuit; the car is still liable to be stationary in traffic.

Radiator

Cocjh1: /* Aftermarket Upgrades */

[[Image:Standard oem radiator.jpg|thumb|left|Standard OEM radiator with plastic end tanks]]
The standard OEM Elise radiator is another weak point in the cooling system. Although it is lightweight, it has plastic end tanks which are prone to expanding and leaking under pressure.

Unfortunately you need to [[Remove the front clamshell|Remove S2 front clamshell]] before you can [[replace the radiator & cooling fans|replace the radiator]].

A upgraded radiator is pretty advisable when going for Honda/Audi/Duratec engine upgrades. Most converted cars on the original radiators seem to blow them up pretty soon after conversion.
{{clr}}

==Leaks==
[[Image:Oem rad end tank leak.jpg|thumb|left|Drivers side end tank leaking under pressure]]
The most common fault with the OEM radiator is cracking/spliting of the plastic end tanks. The first signs of failure are drops of coolent on the windscreen, either drivers or passengers side, but castrophic failure of the end tanks has been known.
{{clr}}

Quite often the passenger side hose is poorly connected (because it is difficult to do) and sometimes the bleed screw can leak.

The OEM radiators seem to have a problem with their manufacture where the main core is bonded to the top/bottom and leaks are all too common.

===Indication of HGF===
Its been suggested in the past that a blown radiator can indicate imminent HGF. The header tank cap is normally the first to vent when the system is pressurised since it only requires approximately 1 bar. The radiator is designed to operate at pressures a lot higher than this and the cap acts as a fuse. However, the header tank is on the lowest pressure point of the circuit and this allows high pressure peaks on the high pressure side (which is from the engine to the rad). Therefore it would be prudent to have a petrochemical test (sniff test) performed on the coolant fluid if the radiator fails to rule out possible HGF.

==Aftermarket Upgrades==
There are basically three options available when it comes to after market radiators that will fit an Elise/Exige. All three are 'all aluminium' and none have the dreaded plastic end tanks. There appears to be only two manufacturers that are making these radiators. The 42mm single row is made by ??? and the 45mm twin row single pass is made by [[Pro Alloy]]. All on-line retailers sell the same radiators, they just badge them with different names to confuse you. Hopefully the following table will help when making your choice for purchase:

Seriously Lotus appear to be the only on-line retailer that sells anything remotely different. For example they have 50mm two row triple pass and 42mm one row triple pass. See website for details. Elise-shop don't do the Pro-Alloy triple pass. They have a 42mm (single or double?) row triple pass instead.

Seriously Lotus appear to be the only on-line retailer that sells anything remotely different. For example they have 50mm two row triple pass, 32mm one row single pass, 42mm one row triple pass. See website for details. Elise-shop don't do the Pro-Alloy triple pass. They have a 42mm (single or double?) row triple pass instead.

The following video will help you understand some of the terms used in radiator speak, like twin rows, dual cores, triple pass etc:

For comparison the OEM radiator is a 32mm single core, single pass. The triple pass radiators are only intended for motorsports and are not recommended for road use.

Radiator

Cocjh1: /* Aftermarket Upgrades */

[[Image:Standard oem radiator.jpg|thumb|left|Standard OEM radiator with plastic end tanks]]
The standard OEM Elise radiator is another weak point in the cooling system. Although it is lightweight, it has plastic end tanks which are prone to expanding and leaking under pressure.

Unfortunately you need to [[Remove the front clamshell|Remove S2 front clamshell]] before you can [[replace the radiator & cooling fans|replace the radiator]].

A upgraded radiator is pretty advisable when going for Honda/Audi/Duratec engine upgrades. Most converted cars on the original radiators seem to blow them up pretty soon after conversion.
{{clr}}

==Leaks==
[[Image:Oem rad end tank leak.jpg|thumb|left|Drivers side end tank leaking under pressure]]
The most common fault with the OEM radiator is cracking/spliting of the plastic end tanks. The first signs of failure are drops of coolent on the windscreen, either drivers or passengers side, but castrophic failure of the end tanks has been known.
{{clr}}

Quite often the passenger side hose is poorly connected (because it is difficult to do) and sometimes the bleed screw can leak.

The OEM radiators seem to have a problem with their manufacture where the main core is bonded to the top/bottom and leaks are all too common.

===Indication of HGF===
Its been suggested in the past that a blown radiator can indicate imminent HGF. The header tank cap is normally the first to vent when the system is pressurised since it only requires approximately 1 bar. The radiator is designed to operate at pressures a lot higher than this and the cap acts as a fuse. However, the header tank is on the lowest pressure point of the circuit and this allows high pressure peaks on the high pressure side (which is from the engine to the rad). '''need more thought here'''

==Aftermarket Upgrades==
There are basically three options available when it comes to after market radiators that will fit an Elise/Exige. All three are 'all aluminium' and none have the dreaded plastic end tanks. There appears to be only two manufacturers that are making these radiators. The 42mm single row is made by ??? and the 45mm twin row in single and triple pass is made by [[Pro Alloy]]. All on-line retailers sell the same radiators, they just badge them with different names to confuse you. Hopefully the following table will help when making your choice for purchase:

Seriously Lotus appear to be the only on-line retailer that sells anything remotely different. For example they have 50mm two row triple pass, 32mm one row single pass, 42mm one row triple pass. See website for details.

The following video will help you understand some of the terms used in radiator speak, like twin rows, dual cores, triple pass etc:
* http://www.youtube.com/watch?v=Ldfuzy_JJUo

For comparison the OEM radiator is a 32mm single core, single pass. The triple pass radiators are only intended for motorsports and are not recommended for road use.

Electrical pack replacement.

If you have a problem with the brushes or the electrical pack in general, a new part can be bought from WOODAUTO. (www.woodauto.com). To order, you will need to call them.

My alternator on a S1 Elise stopped working, so I removed it from the car. Took the electrical pack off, and saw the tails from the brushes were no longer connected to their connections, corrosion was the reason.

The electrical pack off mine had ref. RTM152b. On the Woods website, this came up but their ref. is VRG36884 RMI. This item cost £24 plus VAT. All in all, posted to my door cost me £30.00 with VAT.

Refer to the current guild for a photo of the electical pack. It is the black part which has been removed from the alternater. No major rebuild at all if this is the problem.

Time take, 1hr.

Information added by Britspeed off Seloc.

==Alternator Problem Diagnosis==

Common failures:

Regulator & Rectifier failure:

Battery lights flash on dash, headlights flash on when trying to start. When checking the voltage across the battery terminals readings are usually less then 12v, or can be open circuit and go high voltage 18v. This can have a detrimental affect on the battery - boils the acid/fluid if too high. Easiest solution - Remove the alternator and get checked by auto electrician.

The battery warning light on dash and flashing headlights can also be caused by a flat battery. There is a clicking as the solenoid etc click over but the engine will not start.

Bearing Failure for S2 111s and other model with 4-2-1 exhaust:

Due to the additional width of the 4-2-1 pipes, failure of the rear bearing is not uncommon.
The heat from the pipes cooks the grease until the bearing runs dry and very loud.
Noise produced sounds like metal grinding against metal.

Please add your Info, Just click EDIT

==Removal==
Should take about 1hr:
#Disconnect the battery
#Remove offside rear wheel and wheel arch liner
#Remove plastic cam cover - three 8mm screws
#Remove any exhaust manifold heat shield
#Remove main (largest) wire from alternator 13mm nut. You can't remove the control wire (clip on connector) yet as the heat shield is in the way. Leave this for now.
#Remove 15mm tension bolt
#Remove 15mm top bolt
#Pry alternator from bracket. Start with small flat head screwdriver and gradually move to larger size as the alternator moves out.
#Disconnect control wire plug and remove belt from pully
#Extract alternator from above

*Removing the undertray offers no advantage.

==Regulator==
Very common for these to fail. Can be replaced for about £60.

[[File:Bosch alternator regulator f00m145269.JPG|thumb|Bosch Alternator Regulator]]

==Alternator belt==

You can change the alternator belt by taking off the rear drivers side wheel and plastic inner arch mud guard. Removing the undertray will give no advantage. You will just need a good socket set, though you can get to A and B easily enough with a 15mm spanner.

Loosen 'A' pivot bolt and 'B' tensioner bolt, to allow the alternator to 'swing'.

'C' on the diagram is the tensioner of the belt, loosen this to remove the belt. The tensioner bolt is the 8mm bolt on the end of the arm. It slots into the end of the arm and allows the adjustment. Difficult to see when peering in, but easy enough to locate.

The MG Rover part number for a belt for the S1 is PQS100840 and costs about £10.50 including VAT. - This part number may be correct if you're going to a Rover dealer, but UniPart gave me a different belt when I asked for that number, the correct belt was UniPart number GMV50738 - AL...Ease 27/08/09

'''Tension belt''' to the following on S2:
For heater cars - one way deflection of 6-8mm under moderate finger pressure
For AC cars - as previous but 9-10mm

==Alternator Heat Protection==

Heat-shield fabrics claim to reflect up to 90% of the heat radiated by the exhaust and can function at temperatures unto 2000 degrees Fahrenheit.

The potential downside is that the critical components are also thermally insulated from the inside and could therefore suffer from internally generated heat, ie too much protection could make matter worse.

http://www.merlinmotorsport.co.uk/advanced_search_result.php?keywords=heat

There are option to improve the standard of the existing manifold shielding or to wrap the exhaust. Both of which [[may]] just push the heat elsewhere and cause problems further down the line.

==Sourcing Replacement==

It is not recommended to purchase Chinese manufactured pattern replacement alternators for the Elise, such as those commonly advertised on eBay. They are not built to withstand sustained high revs and are guaranteed to fail prematurely. These include:

*Unipoint (ALT-4212)

Known good models include:

*Magneti Marelli (63321239)
*Bosch - OE part
*02 111s BOSCH 0124225011

== Alternator Re-build ==

Should your alternator bearing pack up and you don't want to buy a new one (£165) or exchange (£120-140) or repair (£40), then you can always fix it yourself.

Doing this may stop you from being able to exchange an alternator at a later date, if you have any worries stop now.

1. Remove the alternator from the car as described above, access can only be achieved through the wheel arch, with the drivers rear wheel removed. Good luck getting it out between the engine mount and the fuel filler pipes, stick with it!

2. Once you've got the alternator on the bench remove the 2 nuts and the 1 screw holding the plastic cover on and remove, then undo the 3 screws (a&b + c not shown!) holding the electrical parts on - remove sideway and slide out with the commutators attached.

[[Image:alternator1a.jpg|thumb|left|Click to make bigger]]
{{clr}}

3. Undo the 4 long bolts, I used a screw driver with a hex shaft and drove it round with a spanner.

4. Using a sturdy flat blade screw drive prise the 2 halves of the body apart. This takes time and you have to work methodically work round from one side to another.

[[Image:alternator2.jpg|thumb|left|Click to make bigger]]
{{clr}}

5. Using a 2 or 3 leg puller pull the bearing off the shaft. I used a small hollow nut to protect the plastic shroud on the shaft, so that the centre of the puller pushed against metal instead of plastic.

[[Image:alternator3.jpg|thumb|left|Click to make bigger]]
{{clr}}

6. Measure the bearing using a vernier. Mine was 35mmOD, 17mmID by 10mm -- SKF 6003.
Go here

Enter you bearing dimensions and obtain a product code. Then take that code over to eBay and see if you can find a 99p replacement!
You could go for an uprated high temperature bearing but make sure the rpm rating is up to the job.

7. Refit the new bearing by either using a deep socket and drift or make a press from a jack, some wood and wedge under something heavy.

8. Align the 2 halves of the alternator and refit the 4 long bolts, tighten each one a 1/4 turn until tight. Refit the electronics in the reverse of disassemble, making sure to push the commutator back in first.

[[Image:alternator4.jpg|thumb|left|Click to make bigger]]

9. Refit to the car, reconnect the wiring and tension the belt as above.
