thats good to know- i have put it in the dart and seems fine.

Prestone good price at the moment at Costco only £11.00 for 4 lts

Had 2 lots of Prestone in the new engine and it seems to go rusty real fast - its now brown opaque rather than bright yellow.
I do have Ally heads now - so wondering if if got the hump with that somewhere down the line.
Rad /block was flushed etc prior to install.

Whats the current thinking team ? I've got a 'cleaning flush' I am going to run through anyway - but wondered what people are using now.

did you use concentrate or the prestone coolant mix

Never used anything other than blue or green, I don’t suppose it will be around for ever though.

Pre-mix. Fleuro yellow.

Prestone concentrate from Costco for me too.
Use it on my defender as well.

the glycol based one? that's what i use too if so
neil.

Used Prestone for the last few years, always my preferred option, never had an issue. Had occasion to use other stuff or top up with water at the track etc, but drained and replaced when back at home.
