Default Coolant

Hi,

I did a search but found nothing as I don't want to bug by posting repeats.

So, anyone use Evans coolant (formerly Meca) in there S4?

I had it in my Scirroco once but I blew that motor with NOS so I never really tested it.

Whats that?

The Meca stuff is a complete replacement and has a higher boiling oint so heat transfer is more consistant.

But since you mention it, i will read up on G12 red stuff.

Default Havoline Extended Life Coolant (DEXCOOL) orange stuff meets G-12 requirements per their technical

data sheets. I think the G-12 spec calls for a phosphate and silicate free coolant; which the Havoline meets. I've used this coolant in several non-GM cars due its superior chemistry and have had good results.

Default I have wondered about that, used to use it in a 13-B, propylene glycol . . .

due to the difference in viscosity you had to use a different water pump and a 0 pressure radiator cap
