I would say I think it is time for a engine coolant flush & then re-fill with Dex-Cool.

Afterwards, always keep the Dex-Cool alittle above the full cold line.
I heard this can happen, if the Dex-Cool is low in the resovoir tank; causing you to oxidize/mixing air in the coolant (or something like that) making the Dex-Cool go bad faster than normal.

See this thread: DEX-COOL information (http://www.grandamgt.com/forum/showthread.php?s=&threadid=8718&highlight=dexcool)


If you are buying the Dex-Cool yourself; get Havoline DEX-COOL Extended Life Anti-Freeze/Coolant (http://library.cbest.chevron.com/lubes/compprd9.nsf/c88c682625e06af6882568db00737ce8/ab30f4d48c33f01a88256b53007f1f4c/), it is cheaper than GM Dex-cool.

Did your cap break in half? Mine has always been one piece.

What mileage are you at?? ...I am thinking that you will be doing a chemical flush of your coolant

Dex-cool is complete garbage. Every car I've ever had with it has had problems with breakdown. On the other hand, the green stuff isn't a very good choice either.

I'm running Toyota longlife coolant. No breakdown, always clean. Something to think about.

The Toyota coolant is red. If you get the coolant from Japan, it's pink. US spec coolant is tinted more red. It's also a longlife coolant. I don't know the website for it. I changed cause I've seen it in action and work with Toyotas.

A few parts on my car are Toyota parts. Superior to GM in every way. Toyota makes wiper blade inserts rather than having to purchase a whole new assembly. Wipes FAR better than stock GM or any aftermarket. FYI the Toyota V6 engine oil filter fits our car perfect. However, I still use the stock AC Delco filters.

You can still buy wiper refills without getting the assembly from most auto part shops.

This Toyota coolant sounds like interesting stuff, ill be looking into it, but is there a way to be sure that there isnt anything there that is unsafe for a Pontiac(or other GM vehicle), that would be safe for the Toyota's? I doubt there is anything wrong with using it in our engines. It just sounds like its Toyota's better version of where GM tried to make dexcool, I like it.

I cant tell if its from the flash or not... but I hope its not a milky/caramel colored gunk, better hope you dont have a LIM leak. If it looks really dark, i'd say its common in our cars. I got that problem, everyone seems to say its normal with Dex-crap.

I also got the same problem with the stupid cap. Gotta use a screwdriver to pry the damn thing off everytime, even when i snap the 2 back together.

When those caps come off in 2 peices it is broken. Seems kinda cheaply made to me.
