DexCool: anyone else have problems?

[62wagon]

I'm in the process of swapping out the intake manifolds gasket on my '96 Tahoe because of a misfire in the #3 cylinder. From the people I've talked to, it's a common issue with the Tahoes and suburbans. Everyone I've talked to hates dex cool, and after laying across my engine bay for 4 hours and not being done yet, I agree with them.

Ralph, be sure when you replace the gaskets that you use the newest GM part number of 89017465. This replaces the old gasket with part 12529094. The difference is the new gaskets are still plastic with the o-rings and now have a washer at each bolt hole made into them to prevent overtorqueing. At the dealership I work at, we have not seen any problems out of the new gaskets. Hope this helps and is not too late.
