not really disbelief, but id like to see 1, a grand prix with 300k on the original motor, and 2, 300k on an original waterpump. longest ive seen a gm pump last is 110k
As for the water pumps lasting only to 110k, you use the green stuff and have answered your own question. The silicates in green coolant eventually wear out the seal on the water pump. Dexcool does not do this.
no one ever said believe trial lawers, but there have been a lot of reported troubles with dexcool. its not the worst, but i dont think its great either.

Nothing is perfect. Cars with the green stuff that aren't maintained properly have problems too. If people open the hood more than once a year and CHECK the coolant, Dexcool will never give them any problems. We have a choice of the green stuff or Dexcool. If that is the choice, Dexcool is clearly superior.

Dave pretty much explained the Dexcool issues.
Dexcool turning into "mud" is not at all caused by mixing the green with Dexcool..There are actual GM bulletins out for their trucks due to faulty radiator caps that would leak pressure, causing the gelling problem. I saw many many trucks, vans with the muddy conditions..Some were horrendous needing adiators, heater cores and waterpumps replaced.. Along with a serious flushing of the block. ( I worked at a GM dealer for 7 years)
Most of the cars were fine, and never experienced problems. And the most common factor was noted by Dave as low coolant and loss of pressure from the caps. There was a part # replacement for those caps in question on the trucks..
Personally I like the green stuff better, but proper maintenance will keep the Dexcool from messing up your coolant system.
Some people here need to chill out and listen before mouthing off like a know it all. it gets old seeing this on these boards lately.
