I have 1999 K1500 with 57K miles.
I noticed a leaking of antifreeze from the front and drivers side rear section
of the intake manifold.
I have read here about the problems with Dexcool and am wondering if anyone
here has had any luck on getting assistance from Chevy on fixing this problem.
If not, what kinda of price should I be looking at to get the intake gasket
Any help I can get before going to the dealer or local mechanic would be
Ian, do you recommend the oil change before or after the engine is started
post gasket replacement?
I continue to have a small leak somewhere on the passenger's side. I only
see about a tablespoon of Dexcool on my drip pan. I did a coolant change a
while back including removing the block drains, but I can't find any drips.
I've put my Yukon up on ramps and gone underneath to no avail. I used a
mirror to look at the rear of the intake manifold but it's hard to see with
the distributor sitting there. It seems I only find the coolant after I let
it sit for weeks, and by then the drips from the engine have dried up. If
it's the intake I don't have a problem getting it fixed, but I need to be
sure. I fixed the leaky quick connect on the heater hose to manifold
connection (what a cheesy POS that is).
