Ok. Understood. But for this thread, I figured the topic of Dexcool would bring me away from any association with the 89 as it stands, but apparently not. And since this is in General and is not a mechanical topic I didn't think it was as important to clarify the year.

Ok, I'm just going to shut up about this. Point taken.

As previously mentioned...I need an answer. This thread has gotten WAY off topic. I appreciate the help guys.

I see no reason why normal green stuff would be bad. But after those pictures thats going to be one hell of a chore flushing that system clean.

Have you read Techinof yet? Search Techinfo on DEX.

looks like some spicy refried beans to me! lol that sucks

Umm, as far as initial water-only flushes, just drain it really good, and use a LOT of duct tape to attach a garden hose to the top hose, and another to the bottom. Lead the bottom one to your bathtub(only if you're on sewer, not septic, and never dump to storm drains!!!)and let her fly. Have someone watch the tub end, and when it runs clear, you're ready for chemical flush. You might also want to reverse the flow through the radiator once or twice, to flush out anything that might be to big to go through to passages.

WOW, yea i'd ditch that car if you can. Some serious overheating problems have occured in that cars life to curtle coolant like that. My car had 130K before the original Dex was flushed and my work trucks also have original Dex and over 140K. None of them have even a spec of that crap in them.

I would send those pics to GM.

other threads have said that prestone dex-compatible and prestone "mixes with all" have the same chemical formula, the only real difference is dex-compatible is dyed orange so it looks like dex, and costs about $2 more per gallon.

they do have the same chemical formula, i've checked. i'd go off of that info. i guess either would work.

Will Dex-compatible Prestone do the same thing or eat gaskets?
