Well, I'm stumped. Last week my upper raidator hose bursted so I replaced it and got a thermostat. Yesterday the u shaped hose bursted on the back of the head right above the intake mani. I'm stumped where is all this pressure coming from? Could I need a new raidator cap? Or I think it is the head gasket. I'm about to winter the car anyway because I've have enough.

I have a b20

 

could be you have old cracked hoses. did u replace your hoses when you did the swap or did you re-use old hoses?

 

I didnt do the swap. A buddy of mine did. But it is the 2nd hose that broke in a week. I don't think it would be the condition of the hoses. The hoses all looked fine except for the huge gash in them from it bursting.

 

sounds to me like you have something plugged like your radiator or something causing it to build up pressure and blow your hoses off. I would recommend getting it flow tested. I highly doubt that your head gasket is bad tho. Good luck

 

Well, I do have a bad headgasket. I know this for a fact. But coudl combustion build up in the coolant lines for the bad headgasket causing pressure in the hoses?

 

i dont think that would cause lines to blow but sounds like sth is clogged in the cooling system.

 

Sounds like bad hoses. If it happens again with the new hoses you'll know for sure. I've never seen the system get that pressurized though.
Flush the system.

 

A properly functioning radiator cap will allow excess pressure to bypass it and dump coolant into the overflow recovery bottle. Coolant, gasses from a leaking headgasket (not good, of course), etc, all should cause the cap to bypass before rupturing cooling system plumbing. Replace the radiator cap.
