[ABH]

A bunch of 1976 Cadillac convertable owners launched a class action suit when GM started making drop tops again.

This dex suit will do just as well. Every car in my family uses it without a problem. If it was as bad as these people imply it would not be used. Unless you think GM, Ford, VW, et al LIKE to pay warranty costs.

It will end up as a case of the nut behind the wheel more than likely.

Jsut change Dexcool like you would the green stuff?

So I buy a high mileage coolant so I can change it like a regular coolant?

This thread will keep arguing and arguing till no end.

I honestly don't care what the GM engineers thought. GM is a business, in the world of business it doesn't mean the best product is being put out. For all we know the head of GM at the time, got a kickback from the number one suppliers of dexcool to switch over to it. It happens all the time.

If you guys like dexcool have fun with it. I am just saying my experiences with it for the most part are don't keep it in your car half as long as they say to keep it in your car.


BTw my 85 Camaro had the green stuff and when I pulled the original waterpump off at 120,000(nearly 40,000 miles longer, and the car was 16 years old at the time) The back of the waterpump was still shiny too...

My 94, that I sold has like 140,000 miles on it still on the original water pump running green stuff for years.

And you had to replace the waterpump on your '98 which is newer then any of those cars, and you still say dexcool is "good for the waterpump"


hehe I think that statement just told me to get a 180* stat, and do a green stuff conversion on my 2000 [img]graemlins/rofl.gif[/img]

This isn't an individual problem, lots of people have expereinced it.

How often do factory warranties last till about 60-100,000 miles...

dexcool doesn't cause problems right away, they cause them further down the road.

Right- Notice that GM was one of the first to switch, and everyone else followed suit. So if Dexcool is crap, then all of the other auto manufacturers non-silicated coolant is also crap? I worked for Volkswagen for a year and a half, and the only time I ever saw coolant sludge was when someone mixed the coolant types. PERIOD. VW's non-silicated coolant is the exact same stuff as Dexcool.

Oddly enough why aren't other brands having the same problem as dexcool?.... I don't think people are arguing the concept, just that particular brand.

For some reason when i got my car i did a cooling system flush and put DExacool you replace the green stuff...New motor is getting Green stuff, heard nothing but bad stuff about DEx cool and its more $$

Not true. There have been similar problems, especially with the early Fords that got the red coolant.

i had to replace my water pump because it cracked due to heavy racing..... the inside was shiny....as same as my new one was.....my radiator cap still shines and so does the inside of my radiator....i race the shlt out of my car, and its just fine..... i dont drive like a wuss so things break... if you say otherwise u dont drive hard enough.... any ways this suit is pretty much bs....ppl have this problem due to ignorance at the jiffy lube puttin wrong coolant in....once u put the wrong stuff in its over...


O and btw i change mine as often as green because i take care of my car.....do you run ur oil till the sticker date....or over cuz "its says it can" plus changing its not just for the coolant it also cleans ur block out and such

True that, same goes for some people who uses synthetic. I've got 145,000 on my car and my coolant looks fine, though the reservoir ran dry one time, lol, so there was a tad of dried orange residue on the dipstick.
I got a little paranoid after see some peeps posting problems and I think I'm going to drain and fill my radiator next weekend, run it for a week, then drain and fill again. Not sure how much % of the old will get replaced by new with this DIY procedure. Maybe I should drain and fill every weekend for a month and prolly 85-90% will get replaced eventually LoL


For the people who flush it out with the Flush Kit. How do you know how much coolant to add in there since it's all water afterwards??? it's not like it's 50% capacity in the Motor and 50% in the radiator....if that was the case then put the concentrate in the radiator and you got a 50/50 mixture....
What's even more confusing is if you have premixed coolant!!! lol

[chas]

if drain at the radiator and the knock sensors that should be sufficient. that should get more than 1/2 the existing fluid. if you change your dexcool at 2 year intervals then you dont need a complete flush.

i dont like premixed since i dont like to buy water. if you use a flush kit just flush the engine as normal but for the first fill up just use water. note how much has gone into the system. check manual for total capacity. figure out how much dexcool you should had added in the refill stage. flush again. you really only need to do this once. once you know how much a typical flush needs to have added back it shouldnt change much. usually the refill amount is how much you can drain with the radiator and knock sensors (so you could just always measure that).

or just buy a hydrometer (i imagine that since radiator fluid's primary ingredient is glycol that green and red should measure the same).

i had a bunch of reddish brown crap on my coolant dipstick when i checked it today but i've never had an overheating problem. my car runs between 185-200 at its hottest in july-august. but im gonna flush it tomorrow, not looking forward to it.

[wantmorepower]

I have switched to green. Why? Orange turd build-up on everything from radiator to hoses. That may be "OK" as far as GM is concerned but not for me. I have never seen regular "non-dex" coolant sludge up lines like dexcool.

BTW... My GF's 2002 grand prix is beginning to get sludge build-up in her radiator and all over the rad. cap as well. I will be switching her to green stuff on the next oil change.

[UsMuScL398]

Wow ive never ever had a problem mines so clean i have no idea what yall have done to ur cars.....my grandparents drive a gm so do alot of my friends and never have they had that problem

[navyblue2000]

Okay, time to lock this one up...

this argument is gonna go nowhere, email me if you don't like what I'm doing.

for the record though (coming from your know it all mod jk)...
I switched coolant at ~25k miles. When I say switched, I mean switched the mixture.
factory comes ~50/50 dexcool. 100% dex is BAD. 100% water is bad...freezes up, plus iron likes to rust. However a happy combo of the two (i found for me to be 75/25) makes perfect harmony. I didn't have a sludgy buildup from 25k-68k AT ALL, and the car cooled like a dream.
