Getting ready to to replace the radiator in my 2005 Cavalier LS (automatic) and it runs DexCool.
-- 2.2 EcoTec.

Are there any better alternatives, additives or mixtures that might help out / work better than just straight DexCool?

I've heard Royal Ice is pretty good, but correct me if I'm wrong on that one.

Just use the cheapest store brand Longlife coolant you can find. Its OAT based like the original stuff.


yup

DexCool is great in vehicles it was designed for. My '99 has had it since day one. The issue with Dexcool is mixing incompatible coolants with it or not keeping up on fluid changes. Dexcool works when you follow directions. Some of the universal coolants like Prestone will say it's compatible with Dexcool. It may or may not be. I'll leave that discussion to the car owner and mfg.

Work better in what way?

I'd stick with a more widely used DexCool antifreeze you can buy off the shelf that meets or exceeds GM requirements exclude Prestone.

No All Makes All Models

No Compatible with Dexool

From my understanding, GM has changed the chemistry since the original "DeathCool" days.

Dex is an excellent coolant, lots of makes using it or very similar formulas. No reason to avoid it anymore.

The phrase "move on and get over it" comes to mind regarding the Dex hysteria...

I just replaced the waterpump and all the hoses on my avalanche. Flushed the cooling system completely. I went with off the shelf prestone long life. I can get it almost anywhere so i won't have to worry about mixing anything.

I agree. I had a 2005 Saturn Ion with the same 2.2 Ecotec. I used an AMAM (it was either Prestone of PEAK) when I bought the car in 2011 and the current owner still has that fill with no issues.
Allegedly, the AMAM coolants are 'dexclones' (same formula without paying GM the license fee) but some people claim they are slightly different....I'd like to know the truth about this? At any rate, they're close enough in formula that you should have no issue using one.

Also remember that Dex-Cool is for sealed systems.

Systems with open flap overflow catch bottles are a NO GO for Dex-Cool.

I've replaced old Dex with new Dex (found a bunch of unopened gallons of concentrate at the home of an ex-employee of a defunct Chevy dealership. Clean system and distilled water has the Dex sparkling to this day.

When I replaced the IM gasket and rad in my 02 s10,I flushed and filled w Supertech all makes. Zero issues. Replaced entire cooling system in my escalade, flushed and filled w OEM dexcool. Works fine. I would stick w dexcool or even all makes, brand u like best or on sale. Even store brand will work. Most likely the last time you replace the coolant anyway

Problem with Dexcool was GM went to a different type of gaskets at the same time they switched to DexCool...

If you hate DexCool, and still want a long life antifreeze, try Zerex G-05.

It's a HOAT, hybrid organic, verses a OAT for DexCool

Napa carries it...

Even our newest 3500 service van has an open overflow tank, not sealed.

All our Silverados use a sealed tank with a pressure cap.

Neither have had any issues with coolant, this despite the fact that the vans have a heat exchanger plumbed into the heater circuit that adds a virtual guarantee of air in the system.

Think about that. Take as long as you like...
