After changing out a leaking water pump I noticed that my cooling fan down at the radiator did not come on for some time even when the temperature got to around 200* F (It did not get higher than this even after taking the car for a spin for about 15 minutes). 200* is an estimate off of the dashboard gauge.
I jumpered the fan to the battery and the motor engaged immediately. I also checked the relay in the fuse box and it checked fine (Haynes manual says there are three but I only have one and there are no other connectors in the block). I did not check is the temperature sensor (aka thermistor) nor did I run an OBD I scan.
Can anyone explain to me the operating parameters of the cooling fan and can anyone give me any thoughts as to my problem or lack of one?
Thank you,
