i have a 322 nail head and it wont stop overheating. i have checked the timing and it seems to be fine. i even pulled the thermostat and it still overheats. i also put a big electric fan on and in the summer it still overheats. this is a newly machined motor. i have heard it could be a bubble but i dont really know how to go about dealing with that. anyone have any suggestions or ideas. thanks
the radiator is not new but it has been rodded and cleaned profesionally. i have not seen any flat hoses, they all seem to be fine. it is in the original car it came out of a 56 buick century waggon.
I looked at your photos and it looks like yer runnin the flex hoses with the spring in um.. I have seen **** get hung up in the springs. with the cap off can you see flow? If not I have also seen impellers fall off waterpumps. Also I guess yer runnin the stock Guage? if so is it working? I guess it is spitting up watter not just reading high?
was the water jackets of the block cleared of ALL debrees and rust? There could be a vacuum leak, running lean. Is your byp*** hose letting too much water in and its not allowing it to circulate through the radiator. hope this helps good luck!
good tip on the flex hose. i also should check the water pump just to rule it out if nothing else. i am going off stock gage and it is spitting all over anyway but a new one couldnt hurt. thanks for the help the dude. also the block was fully cleaned, water jackets incuded. i never thought about va***e leak and i have heard nailheads are great a va***e leaks. i will also check the byp*** hose and running mixture thanks mengestwincustoms.
If you used RTV or some type or sealant in place of a gasket in the water pump area, too much could have been applied allowing it to then break off inside and clog the radiator?
