This. Anything meeting a CAT EC-1 spec should work in nearly anything and will provide the best corrosion protection - But the cooling systems should be thoroughly flushed before switching.

To perform a complete flush prior to switching to EC-1, the cooling system should be drained and refilled with its total capacity 3 times - that's gonna take a lot of time and water, but if you're willing, my hat goes off to you!


I did see this today:


Not a bad price considering. If it'll work in the G20, 300ZX and the Jeep, that'll be good for me. The Matrix, I can go with an Asian coolant.

So I guess if I go that route, I'll do one at a time. First the G20, then the Jeep and then the 300ZX. Flush and fill with distilled water 3x each vehicle?

That or Peak Global was going to be my recommendation. Regardless I would give each vehicle a very thorough flush prior to introducing a new fluid
 
Yes I would use the Peak stuff in everything except the Matrix which you should use the proper Asian coolant
