I have replaced the radiator. Water pump. Thermostat. And my car still keeps over heating. It doesnt do it when i delute the antifreeze alot like 20/80 but i cant do that cause it geta cold here and i dont want to rust out my motor. What do you guys think it is?

 

Is the air damn in place ?

My car overheats at a idle standing still in about 50 seconds i can feel the coolants running threw tje top hose. I dont know why it heats up so fast. If i cant figure it out i might as well drop a real sbc in it and get a 350

 

U might have air in the cooling system also .. to remove air u need to jack up the front of the car as high as u can and let the motor run with the rad cap off .. also u can pump/squeeze the top rad hose while doing this to help

Edit: did u replace the radiator cap? Does the system pressurize ? After it gets up to temp u shouldn't b able to squeeze the radiator hose hardly at all because of the pressure on inside of hose

It makes sense. But would an air bubble really make the whole thing overheat? Ill try it put later though

 

Depends how big the air bubble is ... is our cooling fan coming on ?

Sure is

 

I recently bought a replacement 305 for my TA and undone the drain plug on the block and it was blocked with sediment and sludge. (98k miles) well worth a check, may just need cleaning out and a damn good flushing.

 

Yea my whole car has been acting up way to much for only 85k

 

Holy **** you guys never fail! It was the air bubble. A air bubble about as much as a gallon of antifreeze

 

Hahaha ... that will b 35$ i accept paypal ,credit, debit, cash, or grass Lol JK JK
