So which is the one that rots out cooling systems in the wrong car??

i belive the red stuff isnt the stuff were surpose to use in out 4k, there only used in systems with alloy radiators (i think)

 

4k allways green

Ah- and a Type B coolant??

 

I'm using the first one, the green concentrate, and looking at whats left in the bottle it must be very concentrated in the car!

Interesting point.

Where running a rear mounted aluminium radiator on a KE30 with a 3k.

What type should we be using ?

If it is any help, I use ultra cool.

basic rule of thumb: green does everything, red does only aluminium radiators. check each manufacturer's specific guidelines before using. red apparently lasts a lot longer. I don't think any of them last as long as they make out to be without having some sort of drama like water pumps or gaskets leaking.
