Hi, Today ive been trying to bleed the air out of the water system after fitting my C20XE. The project is ready to hit the road, but i have come across one final hurdle.
Im having problems with bleeding airlocks out of the system. The car gets hot, and NO FAN seems to kick in, (i have tested and the fan works off a switch, also upon testing the cables i have perm 12v to the fan, and the earth which is switched by the temp sensor in the rad all goes to where it should wire wise, but doesnt work... ive also replaced the sensor in the rad, yet it still doesnt work.)
Could anyone tell me when the fan should kick in, when looking at the temp guage?
I have flushed the rad out, and the engine block, and also reverse flushed everything. I have replaced the THERMOSTAT, TEMP SENDER AND TEMP SENSOR, and still no joy.
I can run the car on a normal fan switch, but it doesnt seem to do anything other than keep the temp from rising further.... although upon touching the rad, its cold as ice when the fans turned on.
Also on the interior of he car when i have the heaters on full, and at the hottest setting im getting cold air out of the middle two heater vents, and hot air out of the heater vents by the doors. So im not sure whats going on, and wether the middle ones work off a different part than the vents nearest the doors.
Water seems to boil up and air pockets come out, but its worrying knowing that the fan doesnt work, when the wiring says it should.. its as if the water isnt getting into the radiator....
The rad itself gets hot near the top, but im not sure if that is down to the exhaust or water...
Can anyone help ? Cheers
