I got a very strange coolant problem .

I was on the dyno and noticed that both top and bottom rad hoses colapse with rpm. Thing is , nothing is comeing out the tail pipe ( cracked head) . I tryed to get it flushed BUT , the heater core is clogged . So we bypassed that for now. Everything is BRAND NEW from air filter to tail pipe. One thing wqe considered is maube the wrong pump came in the right box. As the part numbers on the box are right .

Next we figured that the system had air in it. So I opened the rad and proceded to let'r run. Well after a bit. Coolant stated shooting over the fender in a big arc . It didn;t let up at all. So I stopped that . I tried it twice .

Can a pump with the wrong rotation do something likethis ? Fans work , etc . I had a 180 degree T-stat in it. I took it out to get it into storage. As the coolant alwaqys boils over into the overflow .

Car is in storage right now , so I would like to arm myself with stuff to think about for next season before I put the turbo on it .

Thanx alot Thirdgen.org

 

i have seen bad radiator caps do that

 

I had the collapsing radiator hose problem once. The problem was a hair line crack of the plastic along the upper hose outlet of the radiator which allowed air into the system, creating a vacuum. Not sure if that's the same problem you're experiencing but, you might look for a radiator leak and eliminate that from your checklist.

 

thanx guys. No leaks . All new hoses and whatnot along with water pump . I am wondering if it was the wrong part in the rigth box kinda thing.

 

any other suggestions ? Noth rad hoses are being sucked **** . Ths is something I nver heard of before.

 

try filling up to top cold seal it back up start car when gets warm look in hose going to over fill tank look for bubbles. any there then head gasket
