Those tin cans with toilet plungers went around saying "resistance is Few-Tile".

It took almost 4 months for anybody to notice.

 

Thanks for the info and the pics. At first I thought I had the wrong place identified!

 

Great thread.....with 36K on the odometer our's still has the dreaded Dex-cool and maybe we should do a thorough flush and use something else before troubles arise. Appreciate seeing everyone's input!

 

WHY ????? Your vehicle was made for DexCool and came with Dexcool. Everyone, except a few, here uses Dexcool.

You're probably worried about the Dexcool and problems of 10 years ago. Not the same conditions, product or vehicles. Don't worry about it unless you have a transient leak which causes problems and keep it topped off.

Oh, and it has been talked about frequently on this forum. If you use the Search field you'll find many posts with references and discussion.

 

"DREADED"?????? You mean like "has dreadlocks"?

DexCool has a 5 year lifespan, which is longer than most of the others.

Where in this "Great thread" did you find a criticism of DexCool making you think you should change it to something else?

 

DexCool* is not a problem, lack of maintenance at correct specified intervals IS..

 

dex used to attack plastic and rubber, mostly in gaskets and hoses.
sadly, its a lack of trust for me.
anyone who leaves coolant of any kind in their system for more than 4 years is bound to wind up with problems, regardless of brand.
For me, I chose not to trust dex for more than 18 months. Its in my 09 SS and is new(new flush in 3/14) but it will be out when I hit 60k

"lack of maintenance" will cause more damage to components than any product on the market.

 

So grateful for this forum sometimes. I just got this issue yesterday and had it fixed in no time today. Thank you Op for the great instructions and everyone for the feedback. Saved me a ton of time and money

 

IDK bout the aftermarket t-stats. Got one at Autozone, failed within 4 months. This time I got the GM dealer t-stat. Double the price @ 50 bucks and we will see how long it lasts. Definitely looks a tad better built and made in Mexico where my car was made, lol.

 

Just today while debating a exhaust manifold gasket job I spied a puddle of DexCool on the transmission below the t-stat housing. I decided that was an invitation to forget the gasket job, so I pulled the t-stat out and found that the large rubber gasket (the one that is detachable) was not secured to the t-stat. I know that it was at one time,

Anyway reinstalled it with a new gasket.
