Re: recommended coolant - dex-cool?

["therealdmcvegas" <DMCVegas@xxxx>]

That's interesting news. But, just to clarify, are we talking about 
official Dex-Cool made by GM, or are we talking about Dex-Cool 
compatable coolants such as Prestonstone 5/150 that is orange 
colored? I'd also be curious about a little back ground on the 
cars themselves that used the coolant. There could also be 
variables in both the purity of the water used, age/condition of the 
previous coolant, etc... I've only heard of one other vehicle using 
Dex-Cool that has had corrosion problems, but it was a factory 
problem of silica within the engine block, and nothing related to 
the coolant itself.

I don't run official Dex-Cool in my car, I use the Prestone 5/150. I 
do agree that running regular green coolant shouldn't be any 
problem, because we would assume that everyone here does 
infact change their coolant every 2 years anyhow. The only part of 
my cooling system that is original is the engine, the metal pipes, 
and the heater. So If figure that the extra protection that the 5/150 
has to offer is worth it for my parts just in case... If nothing else, 
there is one big advantage to the coolant: Because of the orange 
color, you can quickly identify coolant leaks on the ground to see 
if they are from your car. When I went for my first smog check, the 
tech thought that my car had overheated in line because of a 
sizable puddle of green coolant. No worries for me since my 
coolant is orange.
