Replying to: maxx4me (Mar 04, 2007 12:34 pm) Do you mean you lose two quarts of oil in 6000 miles? That's one quart per 3000 which is good from what I've always thought. You don't say how many mile are on the car and if you know the whole history from new or it you bought it used. If you mean the orange coolant is brownish with gunk in it, that may mean the Dexcool coolant has never been changed or someone added green stuff to it. The Dexcool will turn dark and form goop when overheated or run low with air in the radiator (even though the overflow reseroir is full) the air mixes with DexCool while running hot and causes deterioration. If your crankcase has coolant that has gotten into it, the oil looks milky and like chocolate milk is in it. I'm not hearing that to be what you're saying. But the car needs a professional, trustable person checking it.

How's the tranny fluid (if it's an AT I mean).

Replying to: Mr_Shiftright (Mar 04, 2007 1:03 pm) The description of the goopy precipitate sounds like descriptions of other Dexcool stories and the Fords had a similar description years back. One factor is mixing with air in a system that's not been purged. A seep around the radiator cap allowing air into the radiator instead of recalling coolant from the reservoir allows that air. Mix with hot DexCool and they describe it as crud in the reservoir.

Replying to: Mr_Shiftright (Mar 04, 2007 1:10 pm) I change mine every two years. Fill and drain a couple of times with distilled water. And refill with DexCool. I suspect the car above has never been drained and cleaned in 4 years. I hope it's just needing a flush and cleaning chemical for them to be okay. If air's been in the radiator while running hot the mixing with air makes the precipitates or sludge form. That was the Ford problem and I believe some Century/Regals had a crook in the radiator cap making them hard to fill and purge completely. That was one cause my dealer service manager told me. |

Replying to: imidazol97 (Mar 04, 2007 1:16 pm) I absolutely have no external leaks, and I have not noticed any smoke bellowing from the exhaust. Given the fact that the radiator was drained a little over a year ago, and is now a merky tobacco color, what happened, and more importantly, what is the damage potential to the engine?

I have a 2002 jeep liberty. My key is stuck in the ignition after stopping. the steering wheel does not seem to be locked. The only way I can get it out is turn the engine back on and turn off or step hard on the brake. This does not happen every time. Thanks

We are looking into buying a 99 Chevy Suburban. The guy who owns it, has size 20 tires/rims on it. He told us he had the transmission adjusted for these. Does this make sense? I would appreciate an info on the subject. Thanks.
