I am thinking about flushing out the radiator on my '97. Is it safe to use one of those flush fluids (like prestone flush/radiator clean). My resevoir(sp?) has some sludge looking stuff around the top area and I would like to cllean it out. I have read that a simple garden hose works well to fluse it out, but I dont know how an additive would react to a radiator with plastic tanks on it like ours. Will it hurt or harm the system?  |

For doing a cooling system flush, plain water works fine. I have been flushing cooling systems for a long time, and never used any additives. ________________ GM!!! BRING BACK OLDS!!!  |

I agree, especially because dex-cool is very picky about what it mixes with. It likes to turn into jello.

Plain water is good for the flushing part. Once you get to diluting the coolant, use distilled water. It's only a buck a gallon and you can get it in most drug stores where their gallon water jugs are.

???question about this radiator flush. Being a GM owner of other GM vehicle and HATING the stupid DEX-COOL fluid which is like ACID and GM knows this, i've been told if you drain EVERY drop of the orange stuff out, you can replace it with regular green anti-freeze. Is this true?  |

You can do that. But be sure to flush the system comple- tely (about 15 to 20 minutes) to get all of the Dex Cool out. ________________ GM!!! BRING BACK OLDS!!! |

If a system is designed for DexCool, I would use DexCool, but only because my cooling system has been problem free

There's really no trouble with OAT, you just can't keep it in there for 10 years and expect it to be fine.

i got my car and noticed being a 95 and not a 96 or above, it, thank god, does not take DEX-COOL antifreeze. I have had 3 GM vehicles with almost $1000 repair bills each due to DEXCOOL being like ACID to your engine. Upper intake and many engine/radiator parts are eaten up by this nasty stuff. Even the GM dealership tech says that GM knows the DEXCOOL is junk but its a moneymaker for them. It gets the car by for the length of the worthless warranty, then right after that, people start flocking in to GM dealerships for major dexcool repair problems which keep the dealership service departments so well kept up! They even showed me a 2004 Impala with 2 dexcool leaks at 38,000 miles! I'm glad my Aurora doesn't have dexcool. They're is a REASON why NO other car makers use anything like dexcool. Why switch a good thing?
