Fat Ryan Posted May 1, 2005 Report Share Posted May 1, 2005 i noticed that my coolant light blinked on a couple times. it wasnt on for more than a second though. i checked my coolant, and it wasnt low, but it was thick and sludgy. so i bought some dex-cool and im waiting for some spare time to do a flush. think that'll help? does the light come on when the coolant is only dirty?

1990lumina Posted May 2, 2005 Report Share Posted May 2, 2005 Yeah switching over to DEXCOOL will be to much of a hassle...just flush and use the green stuff Quote Link to comment Share on other sites More sharing options...
Fat Ryan Posted May 2, 2005 Author Report Share Posted May 2, 2005 y is it a hassle? isnt it just flush and fill? Quote Link to comment Share on other sites More sharing options...
1990lumina Posted May 2, 2005 Report Share Posted May 2, 2005 From what I understand, you only use DEXCOOL if the vehicle came from the factory with it...because the seals and stuff are different...but cehicles that didn't come with it don't have the correct seals and gaskets to be compatible with DEXCOOL....plus, you have to be sure to get ALL of the old stuff out of the whole system because any contamination will destroy the different properties of each coolant....so I guess it is just as easy to put the old green stuff back in - Jeff L.

Are you sure the sludge is from the coolant? Does it look anything like oil is getting into the cooling system? Quote Link to comment Share on other sites More sharing options...
cutlsp Posted May 2, 2005 Report Share Posted May 2, 2005 be prepared to change your headgaskets Quote Link to comment Share on other sites More sharing options...
95 3-4 Posted May 2, 2005 Report Share Posted May 2, 2005 Dex Cool turns muddy and sludgy it is crap, It should be flushed out of everything and refilled with a good green. and changed every 2 years No fluid should be in a car for 150k or 5 years like GM recomends with Dex-Cool, coolant maintance must be meticulous on alloy engines or hello headgaskets or hello intake For the coolant light i would flush and fill with nice clean coolant and hopefully it goes out, if not replace sensor in upper left side of rad tank.

DiscoStudd Posted May 2, 2005 Report Share Posted May 2, 2005 Are you talking about the Blazer here? The late 90's Blazers with the 4.3 were notorious for sludging up due to the Dex-Cool. I'm sure if you did a Google, you'd uncover a wealth of info on the subject... Quote Link to comment Share on other sites More sharing options...
Fat Ryan Posted May 2, 2005 Author Report Share Posted May 2, 2005 this is my 2.8 Grand Prix, not my blazer. but you got me worried now. the coolant in the GP doesnt look like its got oil in it. it just looks really rusty. Quote Link to comment Share on other sites More sharing options...
cutlsp Posted May 2, 2005 Report Share Posted May 2, 2005 mine in my white cutlass did too i went and kept filling the system with water and running it for a bit to flush it out. then when all i got coming out of the system was clean water i did a 50/50 mix of the green stuff and water. my car is due for it again this year too its a good idea to do it every year or 2 depends on how much you drive the car :?

GnatGoSplat Posted May 2, 2005 Report Share Posted May 2, 2005 I put Dex-cool in my 89 w/2.8L 40,000 miles ago. Not a problem so far. No sludge, it's clear, bright orange. It couldn't do any worse than the greene Prestone I had in it before... Prestone ate the head gaskets like candy. Only time I've ever seen Dex-cool that wasn't clear, bright orange, was in a Blazer. Any time I've put it in one of my own cars, it's stayed bright clear and orange. Quote Link to comment Share on other sites More sharing options...

GnatGoSplat Posted May 2, 2005 Report Share Posted May 2, 2005 Well, come to think of it, it wasn't a Blazer, it was a 4x4 S-10 pickup of the same body style as your Blazer. Pretty much the same thing I guess! I could be wrong, but I've read all the sludgy crap in them is from some stop-leak pellets GM factory-filled them with. Flush it and refill it, it should be fine. Dex-cool is really not the evil, horrible stuff people have made it out to be. Some people even blame intake gasket leaks on Dex-cool, but ALL GM intake manifold gaskets of the rubber & plastic design from 91 to 10/16/98 will leak.

supreme_style21 Posted May 3, 2005 Report Share Posted May 3, 2005 lol I like how you give 30 minutes before you start to get impatient. It just sounds like old cruddy coolant. Flush 'er out and fill 'er up with green. I don't understand spending more for Dex when they both do the same thing. Quote Link to comment Share on other sites More sharing options...

Everyone who has it thinks that it'll last for 745,000 miles. It doesn't. It lasts just as long as the standard green. And when people run it for 150,000 miles without a refreshing flush, problems quickly erupt. Coolant becomes acidic once it begins to break down. Acidic liquids along with higher mileage cork and rubbers gaskets doesn't equal friendly territory. Quote Link to comment Share on other sites More sharing options...
