Hey everyone. Ive been following this page for a while and have recieved much help from other posts but its come down to me having to personaly ask for some help. I bought my 1984 z28 with a 5.7 chevy 350 motor in it. It had a blown head gasket and i replaced all gaskets since then. My problem now is that from the lower radiator hose after about 10 minutes of idle on the car, it begins to for lack of a better word, boil or squirt out. Its on the lower radiator hose where it meets the water pump. Let me clear it out for everyone, ive removed the hose, its good condition. No obsttuctions or kinks. The clamp is also working and is tight so i have no idea why this is happening. I add a few pics so you can see what i mean by the coolant squirting out. Anyone know whY this could be happening? Ive only come up with one idea. That maybe the radiator is a bit rusted inside and there isnt as much flow as there should be. Any help would be appreciated! Thanks!

 

ok, it is not your hose (i would think) but there is a small hole on the under side of the water pump that leaks when the seal goes bad ... try looking under there ... but my guess is you need a new pump ... if it is a lot more water than come out of that hole, could it be coming from the lower rad neck (where the hose goes on) if so, you should be able to get that fixed for little money ... sorry, just cant see what the pic is of well enough to tell

 

Thanks for the quick reply! I dont think it could be the hose because it gushes water all around the hhose edge, as if the clamp was loose but it isnt. Its not coming from the radiator, definitely from the pump side.
