This is my first time starting a thread......I have a 1993 sentra 1.6L engine no AC.....my cooling fan never comes on and engine temp does not overheat!
Is this normal???

I changed the thermostat and flushed the system....

Can anyone help??

Thanks

well the cooling fans don't run all the time. there's a switch in the radiator that closes when the coolant hits a certain temperature. at least one fan should also run whenever the A/C is on. flushing and filling really won't change that, neither will doing the thermostat. as long as your temp gauge doesn't skyrocket, I'd just shrug it off.

Mine was like that since i bought it but come summertime i got worried about overheating and didn't feel like changing several things till i figured it out, so i just wired a switch with some heavy guage wire and turn it on in the summer when i'm stuck in traffic etc. So far so good!

Mine did not turn on because I had 1/4 of the coolant left... not enough to activate the sensor fan. Every time I replaced coolant, it would leak... out of the waterpump weep hole. So now I have a new pump! No more leaks!

i never notice my fan coming on or turning off. and the temp gauges stays put exactly where it is once its warmed up. i know the fan does come on and off, but i never realize it. :dunno:
