How many of you are still using dexcool
Guys I'm wondering about mine now. Did a swap into a 66 Nova. My catch can is from Jegs and it doesn't have a tube that goes into the catch can. And the catch can has a small hole (like 1/16" diameter in it). Reading this about the air entry, it sounds like I have the wrong catch can. Should I change it? Or is mine fine?

I wouldn't run Dexcool. I converted over to Zerex G-05/distilled water on my fleet a decade ago. NAPA stocks it and it's not expensive. It was the coolant designed by BASF for Mercedes. Look it up and decide for yourself. It's a compromise, but seems to work. I'm still running all my brass radiators and heater cores.

This is exactly what I'm trying to find out............. what is the DESIGNED system? My overflow/catch can is fed from the top, doesn't have a tube going to the bottom, and has a tiny vent hole in the top of it. From reading about the air issues, I'm assuming my catch can is incorrect?

Went to Wally World last night to pick up antifreeze to change out two of my vehicles before winter. They don't even stock the green stuff anymore, only the "good for all colors" stuff.
Availability might be as good a reason as any to switch to the HOAT stuff.
You know, even though I switched to an aluminum radiator I still have the 70's vintage heater core.
That article dzus linked is pretty good yet totally confusing. Maybe G-05 is the answer.
Looks to me like the green stuff does everything it needed to do. Doesn't eat plastic or gaskets, protects water pumps, works with brass radiators and heater cores, doesn't gunk up, is aluminum friendly. Only down side is not extended life (who cares) and there is some controversy about silicates. Also possibly availability.
Damn, when did flipping antifreeze get so complicated?

I used the Toyota red coolant, like it bacause if it leaks it leaves a a trail makes it easier to find leaks, haven't had any problems, its a 30k mile coolant, and since I'm a tech at toyota its free. never seen any toyota's with brown gunk unless someone decides he wants to see what happens when you mix toyota red coolant with the universal green stuff.
