Ok I just fix my A/C system.. And up intill then the car been running just right.. About 200* all the time.. The day I got the A/C fix I over heated major time and blow the rad.. The only think I can see wrong is I have no air dam at all ( Looks like there never been one.. I have a 88 with the 2.8 .. Any advive on what to look for once the new rad in?

 

My car ran 220-240* without the air dam, and 180* consistantly with the air dam. I hope that guides you in the right direction.

 

Ya, I been reading thru thr Cooling forum and it seems that little piece of plastic make a big diffrence.. But it really looks like there never been one on this car..

 

my 85 2.8 doesnt have an airdam either, and no holes indicating there ever being one... Runs cool, so I havnt bothered with it yet.

 

Toehead? Does ur 2.8 have A/C? Im starting to think the A/C is what cause mine to overheat.. Because it never did intill I fixed the A/c

 

It has ac, but as of yet the compressor just cycles on and off very quickly, and doesnt get cold. I plan to convert it soon, once i can find somebody to suck out the r-12

 

Let me know what happends when U get it fixed...

Also.. I have notice there a lot of ducting ( I think thats what it is ) On other camaro's About 1/2 why up the rad. mine is missing.. will this cause a problem also?

 

I was wondering if u ever found out the problem with u r overheating I have an 87 camaro 2.8 same thing i fixed the a/c and right about when it gets cool in the car it overheats only when the a/c is on
I also live in vegas dont help matters but yea only when the a/c is on dont get it hope u got u rs fixed

 

Ya I did. I spilt my rad on one side.. soldered it back up and its running agian.. Added the air dam and its running 20* cooler

 

Hey. Fixed my a/c yesterday. Still no airdam, doesnt run any hotter with the a/c off versus the ac on. Vent temperature is about 37 degrees

 

thats cool.. I added the Manual fan switch and now im running 160* all the time.. And its so nice

 

The manual fan switch is NICE. I usually just leave mine on

 

just wondering what an airdam is and where does it go and if mine dont have one is it easy to add?

 

The Air dam is a piece of plastic on the bottom or the Rad support under the car.. it creates a vacuum under the car as you travail and helps pull air thru the rad as U travail down the road.. And yes it is easy to install.. just 6 self tapper bolts..

 

it is suppose to do that when you need a recharge.it does that so it doesn't burn out your compresor.i just put a pin in mine to get rid of the r-12 and fill with 134.had it over 3 years without any problems

 

if anyone blows their radiator out, i suggest spending the 250 dollars for the summit brand aluminum radiator. yeah its two times more expensive than an aftermarket radiator, but it doesnt have the plastic side tanks. i have noticed a dramatic difference in cooling with the radiator. just my two cents...
