I've got a 2003 Grand Am w/65k miles on it , well maintained. Started
losing coolant about a month ago , noticed some emulsified oil in
valve cover...nothing leaking to the outside.Pontiac says this is
normal(?). I've done enough research to know I'm looking at intake
gaskets , and possibly head gaskets. Does anybody have experience or
input on flushing this shit out of my engine , and replacing it with
regular old Zerex? What are the chances of GM replacing the gaskets
for free..even though it's out of warranty? It's pretty obvious
they've ( GM ) got a big problem they're not correcting.The prospect
of an 800-$1000 repair bill on something I just paid off has me
questioning customer loyalty. Any input greatly appreciated.
Who knows?? Maybe in some cases they do. According to Ian, it is not
that uncommon in Canada, and dealership goodwill may play a big part.
I also agree with Ian that Dexcool is not likely the cause of the gasket
I have never gotten off my soapbox that it is perhaps not the best
formulation available, although it has been several years since I actively
tested OAT technology in a laboratory setting.
At the time, we found the OAT technology to be somewhat lacking in
performance, but we bought the commercial package and sold it to our
clients anyway - at their request - because it was environmentally
Don't bother flushing out the dexcool, the problem is with the
gaskets. Why don't you call a dealership and find out if they
will "good will" the repair? We do goodwill repairs on vehicles
like yours all the time.
If you happen to have gone to one dealership a number of times,
that would be the one to try first. If you've never spent a nickle of
"customer pay" repair money...you may not get anywhere.
OK. I understand that the problem is with the gaskets , and flushing
won't fix that....my take is that the dex cool is eating the
gaskets.What I was trying to head off was a repeat failure after the
repairs are made by replacing the fluid with something else.As for the
dealer , the need to I've got an appointment for them to look at it ,
but don't really want to pay their labor rate. (I'd be happy to let
them fix it for free though.... :)
Dex Cool does not eat gaskets. The underlying problem with these engines
and the gaskets commonly used in them is that the manifold floats and the
gaskets do not stand up to the temperature related movements between the
manifold and the heads. Dex Cool presents some other problems of its own
and it's worth your time to read up on what is on the net about it, but it
does not ruin gaskets.
I can assure you that the problem is with the gaskets, not with
the dexcool. I'm not a huge fan of the extended coolant flushing
interval, but other then that, dexcool is ok.
The new intake gaskets have been redesigned. They seem to
work better so far.
I also can assure you it isn't the Dexcool. My elderly parents have
a 95 Century that had the old style green coolant in it from day one
and at 12 years and 80k mi it is ready for its second intake gasket
job. Speaking of redesigned gaskets are the current ones from GM
similar to the Fel Pro Permadry (metal frame) or is GM still using
the plastic frame gaskets with the metal buttons in them? This
would be for a 95 3100 VIN M.
Hey, I might like that! An American GrandMaster, I like
the sound of that!
No, nothing like that....nobody would bother if that
was the case. Unless you are talking about the "tie-breakers"
and the actual hands on competitions. I've never bothered
attempting those. One of the sharp electrical guys in our shop
went all the way last year and won a trip to some exotic locale.
Then all the techs that had won sat around, told the company
reps that "no, we don't want CSI scores factored into our
Grandmaster testing and results".......what happens, this year
CSI is a factor. Bastards!! (grin)
Did you think about calling a dealership and asking them? They will often
repair the problem. You have to call your local dealership and ask. As for
the price, I just had the gaskets changed on my '01 Montana (212,000KM's on
the odo). Cost was $1100 Canadian. And, like Ian said. Don't bother flushing
the Dexcool out. If it's your gaskets that need to be replaced, flushing the
system isn't going to do anything.
chuckle....snort.........customer loyalty???........uaw loyalty yes........chuckle............it shouldnt be more than 500 bucks for
shops that do a few. i charge 400 plus an oil change. and they can change
their own oil if they want...most shops are just sticking it to the
customer at 750 up.its a 4 hour job if you know what wrenchs are
for......but again, thanks for the laugh....loyalty, i love it.....kjun
