“Coolant used in my 1998 Tahoe causes early corrosion of parts in the cooling system. Even following the recommended flushing, I am finding myself facing a rather large service bill to fix a leak caused by the type of coolant used. The dealer I purchased the car from (new) admitted that they do have this problem with early corrosion, yet Chevrolet is not covering any of the repair cost.”

“I have a 1998 Tahoe (purchase new from edmark Chevrolet in nampa, idaho) with a 350 vortec with 42,000 miles. I have just been told that I am leaking engine coolant from the intake manifold near the rear firewall. A very reputable mechanic says this is very common for this engine and will cost around $400-$500 to fix. While I have owned the car for 6 years I am am upset that a $34,000 car with only 42,00 miles has a problem which is deemed to be common . If it is common, and I suspect it is, why doesn't GM post a bulletin and offer to repair the problem. …”
