Thermostat

Under construction

But until then http://lotuselancentral.com/repair/thermostat.htm

Note: There have been more than a few stuck thermostats in the last year which have resulted in overheating and ECU controlled reduction in boost. As well as checking the obvious (coils, plugs, leads etc.) the thermostat should not be forgotten - an ElanScan run at standstill from cold until the fans kick in is a good way of confirming. - {Al/Dave, thrown this in based on recent experience but it probably wants to go in faults or similar and link to the thermostat section. Catch you after my holiday}
