I need some advice. WIth 40,000 miles on my 2002 3.1 engine. Ive started to
lose anti freeze. It's not a slow leak as I find a puddle every morning
I spoke to a mechanic, that used to work on GM cars and he said its the
Intake Valve Gasket. which will run me about $800. A lot of money for me.
Now the question. Why is GM still putting on poorly designed gaskets that
break in almost every car they sell. Can they be held responsible and
replace the gasket or at least be responsible for some part of the labor
Has anyone else dealt with this and what was the outcome?
If you are within the warranty period, they will probably help you. If you
but raise enough stink, they might help you.
Your problem could be the intake gasket but you have to have it diagnosed
to be sure.
Hope you enjoy your next GM.
These things seem to have a nearly 100% failure rate up through at least
the 2002 model year. I'm not sure if and when a real "fix" was ever
developed by GM. The 3.1/3.4l engines get these failures all the time.
Ours went at about 40k miles, which luckily was still in the extended
Ignoring it is a bad option as the antifreeze often contaminates the
motor oil. When the contamination gets bad enough it can take out the
GM has shown nearly zero interest in taking responsibility for this
design weakness once you are out of warranty.
Did this mechanic of yours actually look at the car? You can't diagnose a
problem without inspecting it. There could be many reasons why your car is
leaking coolant. Take it to a shop and get it checked out. If it does turn
out to be an intake gasket, call up GM and see what they will do for you.
They recently told me they couldn't do anything with my 2001 Montana, but it
has well over 200,000km's on it. With only 40,000 miles on yours, they may
help. But, like I said, get it checked out and don't worry about something
until you know for sure what to worry about.
