What coolant are you guys using?

[Tony1968]

I have 3 vehicles with dex cool in them and they run just fine with zero issues. They are an 07 STS, 07 Sky, and my last is the oldest a 1965 Buick Wildcat with factory engine. The PO used dex cool after they pulled and flushed the block and and heater core along with having the radiator re-cored. And that old sled runs cool as a cucumber in 95+ degree heat in town or on the interstate.

So I've not had any issues with it, and all my other cars run Old School Green antifreeze, the 79 Scout, 85 Bonneville, and 95 F150.

Nice collection of rides 👌 👍

Thanks, but that's only the runner/drivers I've got 11 vehicles in total. 😁 when you catch the bug you get it hard.

I went with Dex cool 😎 Zerex brand if it matters. Plus a dose of Redlines water wetter. Still filling slowly through top radiator hose. Had to pull intake manifold 3 times due to a leak at rear passenger steam vent fitting. Darn Lsxr manifold needs slight shave at that corner. Nothing like having to take a file to your very expensive intake. I'm pretty sure I can RR manifold blindfolded
This was based on things said here and elsewhere and your positive results Mr 500/600

I always wonder when someone asks a question and gets 30 conflicting answers, what direction they actually take. Looks like you’ll either have a positive experience or your engine will suffer a horrid sludge filled death. I’ll bet on the prior no matter what you use. And the Water Wetter surfactant is a good choice. Just my opinion though.

Green global coolant in everything I have to open up. Makes it easy for the next time. In case you haven't heard of it, the global coolant mixes with all types. Regular old green, orange dexcool, yellow Ford coolant, etc...

Didn't know that...

I believe most of the green coolant sold now is actually the global coolant. Look closely on the front of the container. They will say mixes with all types of coolant.

In the garage I got 2 gallons of conventional green antifreeze from O'Reilly's that is listed for pre '95 GM & pre 2000 Ford & Chrysler.

I have a mix of CAT ELC and Fleetguard ELC. It's pretty purple and good for like 400k miles in a big diesel.
