Thread: I Need Help!

Heres whats wrong and hopefully someone will have an answer.
My 97 gtp has been getting air pockets in the cooling system, causing it to blow the coolant into the overflow and over heat. There is a few wet spots ive noticed on the side of the block, under the s/c snout in the area where the lower intake gaskets are. My car does not smoke, there is no coolant in the oil, but its getting air in the coolant. Not long after it gets up to temperature the gauge just keeps going and itll overheat but by that time ive already shut the car back off.. Does this sound like intake gaskets or head gaskets. Please help

I'm putting my money on coolant elbow.

could be a rusted out water pump and the wet spots are from the pump leaking. if its full of coolant and over heating.

grab the water pump pulley (leave the belt on) with both hands, left and right side, ( engine off ) and push and pull each side, back and fourth, if the pulley moves side to side, the pump is dead.

Water pump is an easy and cheep fix too. I think its like $35 bucks at oriellys for a new one.

That would suck air into the cooling system??
Ive had this car forever but everyday it just blows my mind on whats wrong with it.. Id rather just spend the gas in my 85 chevy with built small block then jack with this car

Water pump was just replaced not long ago, it didnt solve the problem

Then I would check your coolant elbow.

you have a 97 so your lower coolant elbow is case on the alt bracket, follow the directions in the how to to the T or the timing cover can break. chances are the lower O ring blow out on the cast elbow. you take the new O ring off the new pair of dorman elbows.

if your leaking coolant it will of course have air, but if its pushing it out only to the over flow tank the rad cap could be worn out, or a head gasket is blown.

if your over heating real fast when its full of coolant id lean towards a head gasket for sure.

Coolant elbow is easy to change and it likely your leak.

A bad rad cap will allow air back inside the cooling system.

I'm on cooling elbow for the leak and you should know that when pressure pushes out coolant, that something has to replace it..even if it's air. Air however compresses easier than liquid, so it's very doubtful that something is pushing coolant to the overflow.
My feeling is start with coolant elbow, have your cap pressure tested and before you start.. pull the cap, top it off and let it get up to temp.. if you see flow..the pump is fine.

Scotty.. aluminum has a tough time rusting out.
