I just did an engine swap, 305 TBI to 350 TPI and the fan doesn't work. I chacked the fuse, swapped relays, and jumped the relay (so I know the fan actually works). I don't know where else to look.

Can anyone help me???

Thanks

Same thing here. So in the mean time, I wired a fan switch, just until I could have time to find out what was happening.

Did you check the CTS at all? I know that my fan just stopped working all together and figured out that was it. Might be worth a shot only about $10 for the part.

 

Maybe a stupid question but what is a CTS??

If your refering to the coolant temp sensor, wouldn't the guage not register if that was shot?

Yea that is what I am talking about, the coolant temp sensor. The guage would still read but the fans wouldnt know when to turn on.

 

is that the sensor on the drivers side above the O2 sensor.

Is there a way of checking it to see if it is bad

Thanks
