			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.

	~~==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.

	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.
