[V8] Radiator Hose Question

[Ingo Rautenberg]

Nathan,

I don't like it.  It sounds to me like you are developing excess pressure in
the cooling system and that can be only due to the following things:

1.  Excessive crankcase pressure due to cyl. head gasket leaking pressurized
air into the cooling system

2.  Defective coolant expansion pressure cap

3.  Clogged radiator

I hope it's just the cap.

Ingo

PS --  Where is your upper radiator hose failing?  Maybe you can integrate
some plumbing pipe/fittings as a temporary measure before you destroy the
next one.
