coolant system pressurized

[screamin_banshee_2003]

hi guyz

 

I am facing problems with my cooling system. I think the piston either in the up or down stroke is pressurizing the cooling system. I changed the o-rings(cool head gaskets) with two diffrent mechanics and it didn't work out.

Installed a used trinity stage 4 head and that didn't work also.

 

Basicly my problem is that coolant is getting pumped out from the overflow tube beside the radiator.

 

My shee would remove all the coolant in the coolant system in 5 minutes. Water is just getting pumped out of the overflow tube. The more i rev it the more the amount of water geting pumped.

 

Is there other gasket other than the orings that could be worn and causing the problem.

Could it be the rad cap

Or maybe there is a hole in my transfers in which air fuel mix is getting inside the water jackets.

Any theories or solution would be appreciated.

 

I would clarify anythin that is not clear.

I just want to ride the shee

 

Thanx in advance

Did you inspect the domes and head maybe there is a crack in it one of them,I have seen it happen very small hairline is all it takes.Are you burning it also ? It is poossible to go through waterjacket when porting transfers highly unlikely but possible+

I've noticed here lately that alot of "mechanics" have no business touching a Banshee.

 

You have to be careful with those o-rings, and make sure they don't get out of the grooves and get pinched. I usually put a thin layer of grease or vasoline on them to keep them in the grooves. Try replacing the radiator cap. They're cheap. It should be able to hold 16psi. You can get them at auto part stores. Find out exactly how much pressure is building up in the cooling system. You can buy testers, that look like a radiator cap with a guage hooked to it. I would take the cylinders off, to inspect them. If you don't have the TORS crap, it takes all of 30 minutes to get the top end off. Then, take the cylinders up to a machine shop to have them cleaned and MagnaFluxed. That is what they use to check for small cracks and leaks.
