New Serpentine Belt Material

[TonyMazz]

Greetings -

I have recently purchased an 04' tahoe and 05' Equinox both of which I love....but check this out....

I asked a GM-Tech on another forum about when to change the serpentine belt in my equinox as I have to (get this) lift the motor mount in order to change it...so I was figuring on say about 50K like my blazer that'd I'd be into that....here is what he wrote back......

"All current GM vehicles designed and manufactured in North America were assembled with serpentine belts that are made with an EPDM material and should last the life of the vehicle. It is extremely rare to observe any cracks in EPDM belts and it is not expected that they will require maintenance before 10 years or 240,000 km (150,000 mi) of use."

Pretty amazing eh ???

So probably any 04, 05 Blazers would fall into that category too right ?

Anyway FYI...

I like DexCool as now the new vehicles don't even have a radiator cap so no contaminants, crappy caps come into play......cap is now on the puke tank.

All you have to do with DexCool is properlly maintain it.....

..and I will probably get another Tahoe within 7 years anyway....or a step up to a Denali or something....who knows...

You are talking about the pressurized resevoir, right?

That is the same setup that is on my Impala. Less than a year after having it "professionally" flushed (this is why I now recommend doing flushes yourself) My dexcool sludged up and plugged the vents on that cap. The pressure built up so high that it blew the intake gasket, busted the heater core, blew the seals in the water pump and busted the resevoir. I just wanted to make sure that you know not to be too secure with your new setup.

I hope that this doesn't turn into a thread about dexcool, because they often get out of hand and cause problems.

Got any pictures of your new rides?

I don't know for sure, but I would guess the end of 2003 for the 04 year models. The TSB is from May 2004 it says all "current GM vehicles".
