So I've got a completely stock 1999 Deville with 90k miles.... looks and runs great (minus the "security error" problem I'm facing right now).











And heres my newest addition..... the 2000 DTS! One owner, just turned 30k miles....MINT!!! Complete woodgrain, gold, and leather package.... an all around solid and AWSOME car!!! I've put a custom dash bezel in with the Pioneer AVIC Z1 w/ Navigation, Complete KICKER Audio System, and the Vogue tire package!

 

Nice, very nice.

 

unkut,

Make sure you have that coolant flushed on that 2000 Deville if it hasn't already been done. The life expectancy for the Dexcool is 5 years or 150,000 miles. I would hate to see you run into any coooling system problems with that beauty. I havea2001 Deville with 29,800 miles and had Mr Goodwrench change mine at 25,000 this past summer. That was the 5 year point for me. I don't take chances with all the horror stories I hear out there about water pumps and blown head gaskets. Good luck. I lovemy Deville.

Thanks for reminding me of this! I just called the dealer I purchased it from and it was completely maintenanced before sold. This included all the filters, oil, and fluids. (Sigh).... so atleast some relief there, haha!

 

Just my 2 cents worth, that DEX cool claim of 150,000 miles is a stretch not only for a Cadillac but for any GM. My 100,000 mile Suburban is in the shop now with manifold gasket leak.My mechanic says clean and flush every 2 years regardless of the claim.

That mightbe overdoing it for me. That would work out to a coolant flush every 9,000 miles on my car.

Yes, assumes the car is driven an average 12,000 to 15,000 miles per year. In any case coolant is cheaper than a top end engine tear down and gasket replacement.

 

Well I only drive the DTS 7-10K miles a year. But now that we've brought this up, haha, the "Check Coolant" came up in the infoarea today.....

Isn't that strange that it happened after we brought it up? Did you buy the car fromA Cadillac dealer? Check the resevoir and if it's low let them know. Keep us informed. I'm sure the Caddy dealer will take care of it (if it was a Caddy dealer)

according to GM Engineers, the coolant's life has little to do with mileage
and a lot to do with time. the protection simply wears off in about two years.
after that, it is back to oxydizing metal & SEALS.

GM Engineering also discourages FLUSHING, specially with CLEANERS
that cannot never be totally removed. Flusha and clean is only adviced when the
coolant system has been severly compromised and the sytem is full of muck.

the recommendation is simply.
- change coolant every two years,
- open the drains, and let out as much as possible then refill
per specs.
- use distilled water for the mix and not hard tap water.
that is it .. pure, simple and inexpensive.


IF you think i'm blowing smoke, go and read this:

IMO, forget the 150,000 miles, forget the 5 years, forget the Dexcool ..
there seems to be a TSB, regarding "Dexcool", and repairs for overheat.
Flush, fill, new thermostat as well as CLASS ACTION LAWSUITS.
many owners of GM cars are switching OFF the Dexcoool..
