Hey guys it's me again
I got a problem with my firebird again

When I start it, it starts fine and it idles fine. BUT when I run it on the freeway after it has been idling at 190-220 it starts to go up to 280
I don't think it over heats because I think the engine should turn off or atleast start acting funny but it doesn't.

I wanna know if there is some type of sensor.

I looked up on ALLDATA about the sensor and having low current resistance when HOT and having high resistance when COLD.
I don't know what sensors it could be but I do not think the engine is overheating.

Any thoughts?

Do you have a AIR DAM under your car?? Without one results in cooling problems.

olveracm

I think it does, what is the purpose of that ?

DJP87Z28

Look under the car and see if you have one. Major part of the cooling system at speeds above 45 mph when your fans should be off.

olveracm

Thanks I will check it out when I get home !
Thanks

olveracm

Yea man i had the exact same problem youre having, overheating when i get on the highway but holds temp at idle and I refused to believe that a piece of plastic was causing my car to overheat despite the numerous times people have told me otherwise on this site.... I bought one and like magic my overheating problem vanished!!!!..... Get The Air Dam........

olveracm

Haha wow that sucks
Well now I have to buy it

U know of any good places that might sell it?
are NAPA or Autozone not included since it is a body shop?

Im pretty sure autozone or Napa doesnst sell them, I got mine off ebay for like 50 bucks, but I think hawks and thirdgen ranch sells them as well....

olveracm

Oooh alright thanks!
And evilemokid94 I know, You think it will still support it?

Will this one work guys?

Mrs.Crasher0083

Trust what everybody says about the airdam!!!!! Everything you described sounded like a bad/no airdam. The pic proved it all. You NEED that and your problem will be solved.

evilemokid94

iTrader: (6)

Yes the one you posted will work

olveracm

Thanks!

olveracm

Hey guys just got the air dam on Wednesday.. What I guys think about it.

olveracm

Is it big enough?

dredre08

Looks good!, did it fix your overheating problem?

Looks good, Let us know if it fixed your problem. After I put mine on it stopped over heating

olveracm

Alright just making sure it's not to small..
And I wish I could tell you but it snowed the day I put it one (how ironic) and now I'm waiting for it to clear up.
I will let u guys know ASAP as soon as a drive again in the freeway.

the airdam doesnt "scoop" air and force it through the radiator. it creates a low pressure zone that sucks air up into the radiator behind it. there have been a few people that actually trimmed down the stock airdam for ground clearance and i dont belive they had any problems. so if its a stock airdam from a 3rd gen f body, no its not too small .

on a side note, the air dam is actually MORE important on the birds, just for the fact they have less air flow comming in from the front of the car than the camaros (they dont have a grill opening after all).

olveracm

"no its not too small ." <-- Haha
But ooh here i thought it did scoop up air. Hmm.. Thanks!

"MORE important on the birds, just for the fact they have less air flow comming in from the front of the car (they dont have a grill opening after all)." <--- yeah I figured that out my self.. Cause yeah there is no grill. But I wanna drive it soon.

To add, the baffling/ducting under the nose works in conjunction with the air dam to draw air through the radiator.
The baffle works similar to an upside down airplane wing.

51 & 52 vary on base or t/a. The air dam you bought appears to be the center section to a Camaro (T/A is very similar)
104 (L & R) are the side pieces to 51 for t/a
49 & 50 are the baffle parts under the nose

olveracm

yeah Thats true..
But i still have left to try to drive it.

olveracm

well, so today i finally got the bird on the highway.. uhhhh.. it reached 220 degrees. or so, (almost 220) uhhhh... eventually when we got off the freeway, it reached the 3/4 of the guage.. seems to be a little better, because last time it hit red line or what ever that # is. uhhhh.. HELP! i think that if we stayed on the freeway, it would have gone higher..

deadbird

check to make sure the is no garbage between your radiator and condenser. make sure the condenser fins are mostly straight.

A 305 TBI is almost to weak to produce enough HP to make it run hot if it didn't even have a radiator. If the air dam didn't help, there is something else blocking the air flow past the radiator.

olveracm

Thanks deadbird i did figure it out.. it was the timming.. it was way off.. the engine used to sound sloppy and now it sounds realy smooth..

only problem is that when i get on the freeway it went over to 220 and then almost over heated and then after like 2 mins it dropped down to 1/4 of the guage..

you think it's the collant?

how much should i get if i need a whole system flush??

travis401

iTrader: (1)

sounds like the tstat may have gotten stuck closed until it heated up to 220 then opened.

olveracm

Yeah the thing it that it's new.. I don't know how or what I'm gonna do a whole coolant flush tomorow and change the coolant tempature switch tomorrow.

travis401

iTrader: (1)

new parts can be bad too...

deadbird

+10

olveracm

Alright well it was the coolant.. I did the flush and it worked just fine..
It didn't over heat on the street and on the freeway.. It seemed to work.. but it was running cool. which is fine cause before it was running really hot!
