okay let me make some things clear......this is what i have

86 Camaro Z28, 305 v8 5.0 TPI

NEW 3 Core Radiator
NEW 16pds Radiator Cap - Pressure Release
NEW Water Pump
NEW Thermostat (185 or 195)

Bypassed the Heater Core
Flushed the whole system with that Prestone Flush Out Kit
Checked Oil
Dumped some of this Car Cooler i saw on 2 Guy Car Garage

I think its called the Aim Dam........thats fine.......

sooooo after all this IT'S STILL OVERHEATING!!!!! Bubblin in the overflow BIG TIME......not some lil bubble bubble its a rumble....anti-freeze comin out tha cap......

What me and a few other people were thinking was that their possibly is a block in the engine......maybe there was corrosion in there n it fell over and its blocking the passage.....

My question is is there a way to pressurize the motor to get a good strong stream of water thru the motor in order to possibly get whatever the blockage in the motor is out of it??

I need help desperately, if someone can tell me how to get the blockage out that would be absolutely great.....its my only car and ive been smoochin rides offa people in fear that ima blow the engine..... <--------says it all

 

was also wonderin out of curiousity........

is it possible to take off all that fuel injection crap, take off the intake and put an intake and 4 barrel carb on the 86 motor??

 

Are you sure BOTH of your cooling fans are coming on when they are supposed to. Had similar problem last summer, could hear the fan so I thought all was good. Turns out one of them had a bad connection and was never coming on.

 

Take the cap off the car when it's nice and cold and crank her up. If the coolant starts bubbling in the first few minutes you have a blown head gasket.

 

if its bubbling alot like u said,it might have an air pocket in the cooling system somewhere. try this...

-drain the coolant out of the motor itself
-take off the thermostat housing and pour in the coolant that way
-install the thermostat housing back on and top off the radiator.
-start it up and run it

i had that in my car when i did my TPI to carb. swap,and man what a headache that was. of course only do what i just listen after you know both fans (or A fan if u only have 1) are coming on.

good luck

P.S. -oh yea,its caled an Air Dam...not a Aim Dam

 

i only have 1 fan........kicks on around 220

what do you mean by bubbling exactly?

if i had a blown head gasket then wudnt i hear a knock? cuz thats what we heard on my moms motor.....

 

Sometimes a blown head gasket will let coolant get in the oil and tear up bearings.....other times it just lets pressure from the engine's compression into the cooling system. This produces air bubbles which hurt the engine's cooling ability, causing it to overheat.

Run it with the cap off and just look at the coolant in the radiator. If you see a steady flow of bubbles that's a pretty reliable sign that you have a bad head gasket. Hopefully not, but it's something you need to check since everything else seems to be good.

 

check and make sure all your hoses are in good shape...mine was overheating for a couple weeks and i replaced the water pump, thermostat housing, and a couple other things....it turned out to be the hose running from the throttle body to the manifold was clogged...replaced that and it runs at 160-190 now

 

yeah im looking into getting that hose shud be in on thursday. take it from there

 

First ,make sure your radiator cap is sealing,,,squeeze the upper hose, if it blows bubbles in the overflow it's NOT, or you can check and see if the upper hose becomes rock hard, as it should after warm up, if not the cap's NOT sealing.....If it doesn't seal, it will boil at a lower temp..
Second, make sure you have the correct water pump, serpentine/non-serpentine spin in opposite directions..see if coolant is circulating by leaving the cap off until the t-stat opens and see if the fow is right.
Third, get a low temp fan switch, and lower t-stat like 160*-180*.

Remember aprox 210* is normal for a factory smallblock, for emission purposes...
