Engine/Transmission (1998.5 - 2002) coolant leak

[MKreiberg]

So there is coolant on the master cylinder and the cowl seal and connection assembly just to the left of the master cyl (passenger side - facing the truck) This is basically directly above the intake cover...



No apparent leaking at idle. I'm thinking head gasket... (too much boost?)



Give the studs a torque?



Stay out of the throttle for a while to see if it actually is something else?

head gasket...



got it warm on the way home, and didn't build boost over 15psi... not a drop.







Will a retorque do anything at this point?

Prolly not...

OR, or, or... it could be the damn thermostat housing leaking and getting picked up by the fan.





Which it sure seems to be, especially after r&r and getting it nice and hot and beating on it a bit :-laf with no further signs of leakage...

Could be the upper radiator hose also. I would look around, pressurize the cooling system and check for leaks. With coolant on the master cyl I'd look for a leak towards the front of the truck, being blown back.
