&lt;hr /&gt;
&lt;div&gt;A &#039;&#039;&#039;Pressure Relief Remote Thermostat (PRRT)&#039;&#039;&#039;, or sometimes just &#039;&#039;&#039;PRT&#039;&#039;&#039;, is used to increase the amount of coolant flowing around the engine.&lt;br /&gt;
The PRRT has a bypass valve opening when the coolant pump is flowing too much coolant for the radiator circuit.&lt;br /&gt;
This valve is reducing pressure difference inside the whole circuit, achieving at the same time a more constant temperature inside the engine.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Note:&#039;&#039;&#039; The acronym &#039;&#039;&#039;PRT&#039;&#039;&#039; means &#039;&#039;&#039;Pressure Relief Thermostat&#039;&#039;&#039;. This setup was developed by Bill Hutchins and used by Rover, MG and Landrover, it has been in use in mid engined cars for 25 years, and an Elise system was previously developed by Simon Scuffham when racing his k-series engined elise. &#039;&#039;&#039;PRRT&#039;&#039;&#039; is actually a misnomer (albeit harmless), allegedly invented by one of the members of the Seloc forum. The PRRT acronym may not actually be recognised by anyone outside of the Seloc forum (including anyone involved in the design, manufacture or assembly of the device) though is perhaps a more accurate description as the second R refers to &#039;&#039;&#039;remote&#039;&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==PRRT Colours==&lt;br /&gt;
&lt;br /&gt;
* Cream is 87°C With Medium Spring: first being used on FreeLander &amp;amp; MGF/TF.&lt;br /&gt;
* Black is 82°C With Hard Spring: Not suitable for Rover K engines.&lt;br /&gt;
* Grey is 82°C With Light Spring: Latest being used on Freelander (MGF/TF ?). Land Rover replace the old stat (87°C) with this one if they have to open the coolant circuit. &#039;&#039;&#039;&#039;&#039;THIS IS THE ONE YOU WANT !!!&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[information added by Yvo Tuk from elise-shop.com]&amp;lt;br&amp;gt;&lt;br /&gt;
The above mentioned colour information is outdated.&lt;br /&gt;
&lt;br /&gt;
There are four manufacturers of the actual remote thermostat units nowadays (2015). &lt;br /&gt;
Some of them stick to the original colour scheme and some deliver their thermostats in the same colour for every temperature.&lt;br /&gt;
We currently ship kits with cream coloured 82°C thermostats.&lt;br /&gt;
We&#039;ve also seen black and yellow thermostats in 82°C.&lt;br /&gt;
&lt;br /&gt;
The temperature is stamped in the actual thermostat which can be seen through one of the hose connections.&lt;br /&gt;
&lt;br /&gt;
==PRRT Part Numbers==&lt;br /&gt;
&#039;&#039;&#039;PCH001190&#039;&#039;&#039; Land Rover cream PRRT kit (including all the hoses and clips needed to make it fit). It is meant to be fitted on a Freelander. (&#039;&#039;&#039;&#039;&#039;BUY this for an early S1&#039;&#039;&#039;&#039;&#039;)&lt;br /&gt;
http://www.mgfcar.de/hgf/freelander_0026.pdf&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEL500150&#039;&#039;&#039; Land Rover Part grey PRRT kit (full hoses kit, similar to PCH001190 but with a non useable plastic elbow with small takeoff). Not easy to adapt to the Elise. This kit may also be difficult to obtain.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PCH003320&#039;&#039;&#039; MG cream PRRT kit. This kit is for the MGF which cooling system is very close to the Elise&#039;s so it requires less modifications than the Land Rover kit. It&#039;s also cheaper and only requires the addition of a piece of aluminium tube as a hose joiner, which can be cut from a discarded tube from the original system. (&#039;&#039;&#039;&#039;&#039;BUY this except early S1&#039;&#039;&#039;&#039;&#039;)&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEL500110&#039;&#039;&#039; Land Rover grey PRRT (standalone) (&#039;&#039;&#039;&#039;&#039;BUY this&#039;&#039;&#039;&#039;&#039;) &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEM101020&#039;&#039;&#039; Rover part number for both Black and Cream PRRT (standalone) - the fact two different thermostats share the same part number could cause some confusion.  The downside with the cream PRRT is that (unless at temperature?) the stat won&#039;t open below 1500-1750 rpm due to the spring rate.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEL000040&#039;&#039;&#039; a metal polo mint replaces the old thermostat in the housing which pulls left out of the water pump before disassembly (BUY this)&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEM00020P&#039;&#039;&#039; is a complete new dummy thermostat assembly with PEL000040 fitted. It also includes the two O rings for insertion of the assembly into the water pump.&lt;br /&gt;

===What parts are needed:===&lt;br /&gt;
&lt;br /&gt;
====Early S1 (Upper aluminium water rail)====&lt;br /&gt;
* Land Rover Freelander kit with cream thermostat (88°C): PCH001190 from Land Rover&lt;br /&gt;
* Thermostat blanking plate (the seal comes with it): PEL000040  from Land Rover or MG-Rover&lt;br /&gt;
* Optionnal: Grey thermostat (82°C, lighter springs): PEL500110 from Land Rover&lt;br /&gt;

===S2 111S with factory oil cooler and recirculation pump===&lt;br /&gt;
The Elise Parts PRRT needs modification of the coolant circuit in order to work properly and also give flow to the heater matrix.&lt;br /&gt;
Basically the T section above the recirc. Pump is connected directly to the heater return matrix. The reservoir hose is then connected to a new T which also connects to the oil cooler outlet and the old thermostat housing.&lt;br /&gt;
Oem hosrs are discarded. This gives a much better flow for lower temps and working cooling circuit. Read more here:&lt;br /&gt;

==F.A.Q.==&lt;br /&gt;
&lt;br /&gt;
* Can I just replace the original thermostat without changing hoses?&lt;br /&gt;
**  =&amp;gt; No you can&#039;t. The thermostat wouldn&#039;t fit to begin with, and it requires a different circuit setup to work.&lt;br /&gt;
&lt;br /&gt;
* What do I use if I have / I want to fit an oilcooler?&lt;br /&gt;
**  =&amp;gt; Go for the &amp;quot;Early S1&amp;quot; list. The landrover Kit has more hoses to play with, it will be easier to adapt. Have a look at [http://web.tiscali.it/elise_s1/index.htm Carlo&#039;s site] (Elise S1) for examples.&lt;br /&gt;
&lt;br /&gt;
* Isn&#039;t there a Kit with the grey (82°C) so I don&#039;t have to buy it separetly? &lt;br /&gt;
** =&amp;gt; Yes, LandRover has a Freelander kit comming with the Grey stat. It&#039;s ref is PEL500150. It&#039;s apparently harder to adapt to the elise because of different hoses/elbows. Beside, most of the cost of the kit comes from the hoses.  So you&#039;d better choose the right hose kit and them change the stat.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;A &#039;&#039;&#039;Pressure Relief Remote Thermostat (PRRT)&#039;&#039;&#039;, or sometimes just &#039;&#039;&#039;PRT&#039;&#039;&#039;, is used to increase the amount of coolant flowing around the engine.&lt;br /&gt;
The PRRT has a bypass valve opening when the coolant pump is flowing too much coolant for the radiator circuit.&lt;br /&gt;
This valve is reducing pressure difference inside the whole circuit, achieving at the same time a more constant temperature inside the engine.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Note:&#039;&#039;&#039; The acronym &#039;&#039;&#039;PRT&#039;&#039;&#039; means &#039;&#039;&#039;Pressure Relief Thermostat&#039;&#039;&#039;. This setup was developed by Bill Hutchins and used by Rover, MG and Landrover, it has been in use in mid engined cars for 25 years, and an Elise system was previously developed by Simon Scuffham when racing his k-series engined elise. &#039;&#039;&#039;PRRT&#039;&#039;&#039; is actually a misnomer (albeit harmless), allegedly invented by one of the members of the Seloc forum. The PRRT acronym may not actually be recognised by anyone outside of the Seloc forum (including anyone involved in the design, manufacture or assembly of the device) though is perhaps a more accurate description as the second R refers to &#039;&#039;&#039;remote&#039;&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==PRRT Colours==&lt;br /&gt;
&lt;br /&gt;
* Cream is 87°C With Medium Spring: first being used on FreeLander &amp;amp; MGF/TF.&lt;br /&gt;
* Black is 82°C With Hard Spring: Not suitable for Rover K engines.&lt;br /&gt;
* Grey is 82°C With Light Spring: Latest being used on Freelander (MGF/TF ?). Land Rover replace the old stat (87°C) with this one if they have to open the coolant circuit. &#039;&#039;&#039;&#039;&#039;THIS IS THE ONE YOU WANT !!!&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
[information added by Yvo Tuk from elise-shop.com]&amp;lt;br&amp;gt;&lt;br /&gt;
The above mentioned colour information is outdated.&lt;br /&gt;
&lt;br /&gt;
There are four manufacturers of the actual remote thermostat units nowadays (2015). &lt;br /&gt;
Some of them stick to the original colour scheme and some deliver their thermostats in the same colour for every temperature.&lt;br /&gt;
We currently ship kits with cream coloured 82°C thermostats.&lt;br /&gt;
We&#039;ve also seen black and yellow thermostats in 82°C.&lt;br /&gt;
&lt;br /&gt;
The temperature is stamped in the actual thermostat which can be seen through one of the hose connections.&lt;br /&gt;
&lt;br /&gt;
==PRRT Part Numbers==&lt;br /&gt;
&#039;&#039;&#039;PCH001190&#039;&#039;&#039; Land Rover cream PRRT kit (including all the hoses and clips needed to make it fit). It is meant to be fitted on a Freelander. (&#039;&#039;&#039;&#039;&#039;BUY this for an early S1&#039;&#039;&#039;&#039;&#039;)&lt;br /&gt;
http://www.mgfcar.de/hgf/freelander_0026.pdf&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEL500150&#039;&#039;&#039; Land Rover Part grey PRRT kit (full hoses kit, similar to PCH001190 but with a non useable plastic elbow with small takeoff). Not easy to adapt to the Elise. This kit may also be difficult to obtain.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PCH003320&#039;&#039;&#039; MG cream PRRT kit. This kit is for the MGF which cooling system is very close to the Elise&#039;s so it requires less modifications than the Land Rover kit. It&#039;s also cheaper and only requires the addition of a piece of aluminium tube as a hose joiner, which can be cut from a discarded tube from the original system. (&#039;&#039;&#039;&#039;&#039;BUY this except early S1&#039;&#039;&#039;&#039;&#039;)&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEL500110&#039;&#039;&#039; Land Rover grey PRRT (standalone) (&#039;&#039;&#039;&#039;&#039;BUY this&#039;&#039;&#039;&#039;&#039;) &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEM101020&#039;&#039;&#039; Rover part number for both Black and Cream PRRT (standalone) - the fact two different thermostats share the same part number could cause some confusion.  The downside with the cream PRRT is that (unless at temperature?) the stat won&#039;t open below 1500-1750 rpm due to the spring rate.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEL000040&#039;&#039;&#039; a metal polo mint replaces the old thermostat in the housing which pulls left out of the water pump before disassembly (BUY this)&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;PEM00020P&#039;&#039;&#039; is a complete new dummy thermostat assembly with PEL000040 fitted. It also includes the two O rings for insertion of the assembly into the water pump.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
===What parts are needed:===&lt;br /&gt;
&lt;br /&gt;
====Early S1 (Upper aluminium water rail)====&lt;br /&gt;

&lt;br /&gt;
====S2 and Late S1 (Lower Aluminium water rail)====&lt;br /&gt;
* MG-Rover MGF CVT automatic kit with cream thermostat (88°C): PCH003320 from MG-Rover&lt;br /&gt;
* Thermostat blanking plate (the seal comes with it): PEL000040  from Landrover or MG-Rover&lt;br /&gt;
* Optionnal: Grey thermostat (82°C, lighter springs): PEL500110 from Landrover&lt;br /&gt;

===Fitting modifications===&lt;br /&gt;
Don&#039;t take values as a gospel, go progressively:&lt;br /&gt;

&lt;br /&gt;
===S2 111S with factory oil coolet and recirculation pump===&lt;br /&gt;
The Elise Parts PRRT needs modification of the coolant circuit in order to work properly and also give flow to the heater matrix.&lt;br /&gt;
Basically the T section above the recirc. Pump is connected directly to the heater return matrix. The reservoir hose is then connected to a new T which also connects to the oil cooler outlet and the old thermostat housing.&lt;br /&gt;
Oem hosrs are discarded. This gives a much better flow for lower temps and working cooling circuit. Read more here:&lt;br /&gt;
&lt;br /&gt;
==F.A.Q.==&lt;br /&gt;
&lt;br /&gt;
* Can I just replace the original thermostat without changing hoses?&lt;br /&gt;
**  =&amp;gt; No you can&#039;t. The thermostat wouldn&#039;t fit to begin with, and it requires a different circuit setup to work.&lt;br /&gt;
&lt;br /&gt;
* What do I use if I have / I want to fit an oilcooler?&lt;br /&gt;
**  =&amp;gt; Go for the &amp;quot;Early S1&amp;quot; list. The landrover Kit has more hoses to play with, it will be easier to adapt. Have a look at [http://web.tiscali.it/elise_s1/index.htm Carlo&#039;s site] (Elise S1) for examples.&lt;br /&gt;
&lt;br /&gt;
* Isn&#039;t there a Kit with the grey (82°C) so I don&#039;t have to buy it separetly? &lt;br /&gt;
** =&amp;gt; Yes, LandRover has a Freelander kit comming with the Grey stat. It&#039;s ref is PEL500150. It&#039;s apparently harder to adapt to the elise because of different hoses/elbows. Beside, most of the cost of the kit comes from the hoses.  So you&#039;d better choose the right hose kit and them change the stat.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;==== Children in a Lotus ====&lt;br /&gt;
&lt;br /&gt;
Having a kid does not necessary mean the end of Lotus ownership. Many owners have kids and regularly take them out in the Lotus. &lt;br /&gt;
&lt;br /&gt;
There are many makes of seats for all ages that fit the Elise, although none of the factory fitted seats have IsoFix fitments so child seats must be belt fitted. &lt;br /&gt;
&lt;br /&gt;
There&#039;s a vast choice of child seats available and also a lot of variations in the Elise seat design/padding over the years the car has been manufactured - so try before you buy.&lt;br /&gt;
&lt;br /&gt;
==== Child Seat Safety Law ====&lt;br /&gt;
Whatever you buy make sure it complies with the up-to-date Child Seat Safety Law&lt;br /&gt;
http://www.thinkroadsafety.gov.uk/campaigns/childcarseats/childcarseats.htm&lt;br /&gt;
&lt;br /&gt;
==== Child Seat Types ====&lt;br /&gt;
http://www.childcarseats.org.uk/types/index.htm&lt;br /&gt;
&lt;br /&gt;
The following seats have been found to fit various Elise/Exige seats and provide a good starting point for the test fitting trip to Halfords or Mothercare.&lt;br /&gt;
&lt;br /&gt;
==== Baby Seats - Group 0 (-9 months) ====&lt;br /&gt;
*Maxicosi Cabrio&lt;br /&gt;
*Brittax rockatot&lt;br /&gt;
*Mamas and Papas Primo Viaggio SIP (without base)&lt;br /&gt;
*Jane Travel System car seat - group 0+ ( to 13kg, -18 months)&lt;br /&gt;
[[Image:P1030003.JPG]]&lt;br /&gt;
Jane Travel System car seat&lt;br /&gt;
&lt;br /&gt;
==== Child Seats Group 1 (9 months - 4 years) ====&lt;br /&gt;
*Maxicosi Priory (Note, not S2 Exige Touring with probax, seat very wobbly)&lt;br /&gt;
*Britax Duo plus&lt;br /&gt;
*Britax Prince (S1 Exige with motorsport seats)&lt;br /&gt;
*Maxicosi Tobi (Fits S2 Exige Touring with probax superbly) 2009 model fits VX220 with cloth seats &amp;quot;better than any seat/car combo&amp;quot; the shop folks have ever seen. Also a great fit for Recaro front seats in the Evora.&lt;br /&gt;
*Mama and Papas Pro-Tec (Fits brilliantly in an S1 with cloth seats)&lt;br /&gt;
*Romer - Eclipse (Fits a standard S1 seat nicely).&lt;br /&gt;
*Britax Evolva123 (Groups 1,2&amp;amp;3)- suitable for the rear seats in the Evora (Base too wide for standard S1/S2 seats)&lt;br /&gt;
*[http://www.kiddy.de/en/car-seats/9months-4years/kiddy-phoenixfix-pro-2.html Kiddy Phoenixfix Pro 2] (S2/S3 Elise with standard Probax seats)&lt;br /&gt;
====REAR FACING SEATS==========&lt;br /&gt;
*Britax Hi Way II (Elise S2)&lt;br /&gt;
&lt;br /&gt;
==== Child Booster Seats Group 2 &amp;amp; 3 (4 years - 11 years)====&lt;br /&gt;
*Britax Hi-Liner&lt;br /&gt;
*Halfords Michelangelo&lt;br /&gt;
*Britax Adventure&lt;br /&gt;
*Recaro Milano&lt;br /&gt;
&lt;br /&gt;
==== Push Chair/Buggies ====&lt;br /&gt;
You can even get a push chair to fit in the boot of the Elise!&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Quinny Zapp&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Quinny Zapp is used by a few owners, and it can also take the Maxicosi Cabrio seat. The Zapp is a tried and tested fit in the boot of an S2 Exige S too, without even removing the wheels (the pushchair&#039;s, not the car&#039;s!)&lt;br /&gt;
&lt;br /&gt;
[[Image:QuinnyIn.JPG]][[Image:QuinnyOut.JPG]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Petite Star Zia&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Petite Star Zia is a similar design and fits in the boot of an Elise S2.  It also reclines and has a basket underneath, and has a slight price advantage.&lt;br /&gt;
&lt;br /&gt;
[[Image:ZiaInS2.jpg]]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Quinny Yezz&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
A new kid on the block, The Quinny Yezz, even smaller than the Zapp!!&lt;br /&gt;
&lt;br /&gt;
I was given one by Quinny as a fathers day present to review in a mans point of view, obviously I tried it in my S1 boot, it fitted with ease and with room to spare. It even fits in the passenger side footwell.&lt;br /&gt;
