Our 2000 gmc 2500 7.4 engine the antifreeze runs between the valve cover and the intake cannot find where fluide come from, check hose fitting, help
hello, i had a 1997 chevy dually, had same problem, the way gm changed their clamps for hoses, now the clamps sorta hold their self, there made of plastic, and they slip into each other, they are like male and female connections, they slip into each other, i would check all radatior hoses, heater core hoses, i had 6.5 turbo diesel, great motor, only thing is the clamps for heater hoses was plastic, just like on the rocker arms, on the 6.5 they have a nylon plug that holds rocker arms in place, keeps them moving from side to side, they have to be changed at least, 150,000, mine broke off, had to replace 2 pistons, pushrod came out went into motor and broke the skirts off two pistons, very expensive, i would check all clamps with the plastic male to female, ends, maybe that will help, also check thurmostat cover, been known to leak a little too.
