i have just put new water pump headgasket timing belt etc on my car
it now runs and fine when idleing but when accelerating
there is a lot of pressure coming out of the bottle
under heavy acceleration it blew of the radiator hose that i hadnt tightened properly .

i had to bypass the heater matrix yesterday due to it bursting
could this be the main cause ?

its a 1998 escort gti ?
any ideas before i smash it up with a hammer lol
cheers kev
