Hi there,
My 230TE overheated the oher day (lots of steam - and yes I am aware the antifreeze level needs checking!) and today I finally got round to checking the reason. This is proving harder than I thought - I've checked the forums and cannot find anything similar given what I have checked/done so far.
Thermostat is OK. Tested it and checked the radiator heats up and the heater heats up. Engine temp around 80C during normal motoring, which I understand is what it should be. Temperature rises only when stationary and fan does not cut in.
So, if fan does not cut in must be the switch (its gone before). But I've tested the fan switch (two prong - electromagnetic fan, no aircon) and this is fine going open circuit at about 100C. I've also bridged the twin socket connector for the fan switch, which should have caused it to roar into life - alas it did not! I have checked for, and found, feed voltage at the connector to the fan switch on the engine.
Fuse D and Fuse 7 are OK.
SO - am I right in thinking there must be a problem somewhere after the fan switch on the engine? Possibly with the wiring (she is getting old bless her!) or with the electomagnetic clutch itself?
If anyone has any other ideas please let me know!
