over heating?
« on: 12 August 2008, 02:30 »
i have read most of the topics on this but none really pin point any thing thats happening to me!
this is what happens, start her up move 2 miles then the temp gauge is 3/4 and higher. no working rad fan, no lose of coolent and no steam.
i normally just turned the heater fans on full and on top heat to get it down and that worked but now it wont send hot air in at all.
some times the fan comes on randomly when over 3/4 on the gauge mostly when turned off.
i have changed the thermostat which has done nothing. unsure please help.

thanks

jack

That sounds like air in the the cooling system.

Search how to bleed the system. Think RJ has a guide :smiley:

if it doing it within 2 mile I'd suspect the temp sensor or wiring is at fault, if no other symptoms of overheating present themselves. do you have an MFA, and if so whats the oil temp?

did your coolant system operation. found out my rad has a small leak. i have lost coolant hopefully the rad leak. fan works, prob with the thermostat it didnt opens untill i turned off the engine at about 3/4 on the temp gauge is that ok? i dont think so.

and you rock rj your like an internet mechanic.

aha, stuck thermostat, bad!  do you have pas? if not its easy, if not its not so easy :grin:

follow the rad hose to where it connects to the front of the engine, this plastic flange is where the stat is located :)

edit: did you check you get a nice spray o coolant to the top o the header tank when the engine is revved?
