The engine fan on my saturn does not come on when the car gets hot. I have checked all the fuses and the relay. I checked the fan and I replaced the coolant temp sensor. I also check the voltage at the harness and it was 5.02. I am stumped I don't know what else to try. The fan does come on when the a/c is on. Can anyone help?

So how high does ur temp gauge go?The fan doesn't come on till 3/4 or sometimes the tip of the red on the older models like urs when gauges get older.U could even have a bad gauge or gauge sensor. Do u have a temp gun there cheap now and can use them for alot of differnt things.

I changed out the sender sensor and let the car get up to about 3/4 and the fan came on. Thanks for all the help.
