I would like to thank the guys who replied to my thread I dont no how to reply to some of the guys cause I am new at this but there is one guy named SLEAZY I mean eazy thought he was rude but anyway back to the topic my car is not over heating it is just running HOT in the summer which is normal for these cars but my car has not been touched before and i would like any info from any other members what they have done to make there cars run cooler like around 170 or around there . I would like to get the info off the Tech section from ***** on the dual fan section but cant down load it . CORBI s 85 thanks for the reply I will try to get back to you soon or get back to me . I would appreciate if anyone else has any info to pass on to me I would be grateful.

 

Ok well if you're not overheating, then you just need tips to make it cooler than normal.

First, a lower opening thermostat. As suggested a 170 thermostat is about as low as you can go before you run into borderline territory for EFI systems. A min coolant temp is required to keep the engine in closed loop.

Now this is useless still if you don't have an active way to keep the temps down there. This is where a fan switch or ecm programming come into play. You need to have the fans come on just after 170, like 180-185 and shut off again at 170. A manual fan switch or wiring it so both fans are on all the time are ways to do this.

Another tip to keeping it down is removing the rear hood seal to allow underhood hot air to vent out at speed. Removing hood insulation runs along those lines.

 

Heres what i di last spring. Two new top and bottom hose's. 3 Core alum rad (optional) got it cheap. 160 Thermostat. I would tottally back flow ther rad. Good mixed coolant, i do it 30-70, 70 being water. Three bottles of water wet'er new rad cap, i forget the pressure. big difference in cooling. I also tied the two fans together, in parrellel. To a toggle switch, on/off. when the car heats up, i flick the fans and it cools fast. i would say 40-50% increase is length to cool. the first tiome i tested it, i was almost shocked. so theres my recipe.:lala:

 

1. 170* thermostat
2. Wire the fans together so that they both come on when the primary is engaged
3. Use Water Wetter, water and a pinch of coolant during the summer
4. Make sure you still have a chin spoiler
5. Clean all the garbage out from in front of the rad/ac condenser
6. Get an aftermarket fan switch or have someone change the fan on/off values in the PROM

These are things that will work and actually show a cooling improvement. Guys, for the love of ***, stop filling these threads with complete garbage. Nobody cares how enlightened you are. A little joke or 2 doesn't hurt but come on, enough.

Ray, welcome to thirdgen.org

Thanks,

Also make sure that the little foam/rubber strips along the sides of your rad are still in place. Every little bit helps...

Oh and if it ever gets too hot, turn the A/C off and put the heater on full to help get it under control. Again, every little bit helps.

And don't mind easy, he's just a kid. Welcome aboard.

 

Not only does cranking on the heater help to cool the motor when it starts to get too hot it is also a very good character building exercise in say July or August.

After I cleaned all the crap out of the rad area I had no more problems even w/out the chin spoiler although I have one on there now.

 

Hey you do what you've gotta do.

 

I put a 160 in today to try out... a 180 was in there already.

 

I found that a 160 will from time to time depending on conditions and outside temperature will force the engine back into enrichment mode. It just isn't enough for the engine to hit closed loop properly.

 

Is there any immediate warning it's gone into enrichment mode other than possible performance loss or checking plugs?

 

It will idle high when its in enrichment mode usually like its trying to warm itself up in the morning when you first start it.

 

my car doesnt run any hotter in winter then in summer

i dont see why you woudl want to lower the temp, cause 2 cold isnt good either.

 

Some of you guys should go back and read the original "keepin it cool" topic from a couple days ago:

Putting in a lower temperature thermostat WILL NOT lower maximum engine temperature in warmer weather, period.

 

Having a more efficient cooling setup will allow you to run you engine at cooler temperatures even in warm weather.

Before I run on track I flip my fan switch on and force the engine down to around 175-180 degrees. Running on highway, even in "warmer weather" keeps my engine running around 180 degrees.

I think the original post was not how to make it run colder, but how to make the engine more efficient at removing heat.
