I've read on a couple of websites that the newer Dexcool was reformulated....which makes sense...being that GM's continuing to use the "Dexcool" brand after the revelation of the old formula's problems, I think it's safe to conclude that they would alter it to make it safe to the cooling systems/gaskets.
been there done that, i had an 01 , 3.1 same situation, its the upper and lower intake gaskets, its a common problem with these gm models, its blamed on the dexcool antifreeze, u cant mix it with other antifreeze, there is a class action suiet going on now about the dexcool.. i replaced the gaskets but it had already been too hot...had to replace engine.....and used only dexcool, running excellent..
There has been a very lively discussion going on about "Red" or Dexcool
it is not mud. Most 94 and later GM'S come out with Dexcool antifreeze. If it hasn't been changed it will kinda look like mud. My recomendation would be to flush the whole cooling system and replace with regular or universal antifreeze.
ignore that last answer, only use green antifreeze if your system has been converted over, you use factory gm coolant called dexcool, it is orange.I do recommend converting your system over to green because nomatter what gm says, I've ran onto a lot of problem with dexcool, dexcool gums up so bad over time. Just tell your machanic you want your system switched to green, he will do an intense job of flushing out entire coolant system if he is a good machanic.AnswerGreen 50/50 anti-freeze
My mechanics routinely make this change from Dexcool to "regular" antifreeze upon customer request. They say they've never had an intake manifold gasket failure with the green antifreeze as has been common when Dexcool was used. A GM dealership parts manager I know told me it's fine to go to green antifreeze as long as the orange "gunk" has been flushed out. He went as far as to "suggest" the company "might know" Dexcool has problems, but they can never admit it. ;) Just remember to change every 2 years now. It is perfectly safe to do this however the vehicle will be damaged. Dex-Cool is a specially formulated anti-freeze for some vehicles and must be used to replace antifreeze to protect the engine and radiator. The question is why are you replacing it after only 5 years. I have a 1987 Mazda RX7 (my second car) with the original antifreeze. Unless something has broken you should never "flush" your radiator for any reason. Dex-Cool has been shown to corrode the plastic gaskets that were used in the Venture for some years. Hence, after some time, the manifold gasket will rupture and necessiate a costly repair.
Yes. The extended release version of Opana has been reformulated to make them tamper resistant,crush resistant (to prevent users from snorting them)and has a gel matrix that will prevent users from mixing with water in preparation for injection. The instant release Opana 5 and 10 mg aren't reformulated or tamper resistant.
GM has it for you. I believe they make it in Mexico, where your caddillac was made. hummer,etc. Gm has been in Mexico since 1935. So im sure they have plenty of dexcool handy.
The correct coolant is DEXCOOL it has an orange color to it. If your coolant is green the coolant has been changed. It has been found out that DEXCOOL was bad for Aluminum heads and gaskets. Best to switch to the green coolant.
The original coolant would have been "DexCool". The cooling system should be flushed and coolant replaced every 5 years or 100K miles if you use DexCool.
Most 2000 GM cars were filled with the RED Dexcool coolant. Using the standard green fluid after the Dexcool has been used can lead to clogged coolant passages and destroy the engine.
originially Dexcool which is orange color. if its been replaced with glycol, its green.
Be sure that you have adequate antifreeze in your car, the temperature has been dropping sharply.
