Vehicle make/model 2001 GMC Sonoma
Mileage = 61000
Engine size = 4.3L V6
dash lights = none
codes = none
work done prior = none
work done to repair = none
tech = MW
question = My '01 Sonoma V6 is leaking coolant. I have looked and I
cannot find where the leak is coming from. It appears to be leaking down
the back of the engine. Any suggestions on where to look?
MW:
A common area of coolant leak on the back of the 4.3L engine is the lower intake manifold
gaskets. From under the truck you can follow the trail of coolant up to where the lower
intake manifold meets the cylinder head. Coolant residue may be visible and the starter as
well.
You can also lay on top of the engine (not running)and look as far back as you can to
determine if infact that is where the leak is coming from. Best way is to have the cooling
system pressure tested by a professional.
