Hey Guys,

So my fan switch is broken and I want to get it changed before the weather starts to warm up.I can get a switch that has the temp range that the factory does but I thought about changing to a slightly lower temp.

I don't want to go too much lower so that the fan is on all the time but I thought there might be benefit in an older car to let stay just a little cooler. The harness is not an issue because it is already missing.

 

The unit I am looking at is 197F on 179F off. Does that seem like a good fit? Or should I just stick with one with the factory specs?

 

Any temp range options you guys are aware of?

 

Thanks,

That should be fine. I run my trans am with 195 on, 185 off and a 180 thermostat.

Where did you find the 195/185 switch? What model of vehicle would I look for for those at the parts store? I feel like that is a more ideal range.

 

I have an OEM thermostat. That should be 180, right?

 

Thanks

Edit: Just saw that you said Trans Am

Oem thermostat for loyale is about 190. I've been running a 180 in one of mine for a number of years now, never noticed any ill effects, but the heater seems a little lower output.

Can't help you with the switch as the Trans Am is tuned port injection and the fan is ECM controlled.

 

I would look on some hot rod forums.
