I have a 195 degree thermostat in my car, its an 84 camaro, It has an electric fan which goes on at 220 degrees. I want to take the thermostat out for the summer, I know on the older cars you can take the thermostat out with no problem, but since this car has a computer, will it mess anything up? And will my fan be confused as to when to go on?

 

what will you be trying to accomplish by doing this?

 

You're better off to leave the thermostat in it. The system is designed to flow the water at a certain rate, and if you get the water flowing too quickly it will actually run hotter. Something about not staying in the radiator long enough to coll down as much as it could otherwise. Sounds strange, I know, but has been proven many times over. Granted they make high flow water pumps and thermostats, but those still fall within that range.

I believe on the older cars like yours the only thing that will affect when you fan comes on is the water temp, although if I'm wrong hopefully someone will point it out. My 91 has dual fans, the primary fan is controlled by the computer but the secondary fan is controlled by a temp switch. You could always change your fan temp sensor switch for one that comes on at a lower temp.

My recommendation is to leave the thermostat in, maybe change to a 160 if you want to, but don't remove it.

Just my two cents....

i agree i recommend using a 160* stat

 

I would just change the fan sensor to the Hypertec 160 and leave the thermostat alone.

 

Who told you that you could take the therm. out of the older cars
with no problem? It might work on the track but not on the street!
By just replacing it with a cooler one will retard your total timing advance because the comp. will never see your engine warmed up to operating temp. :nono:
