anyone useing waterlees coolant?

[Black VXR]

just wondered if any of you are using waterless coolant and if so, where did you buy it and what do you think about the product please?

I used it several times in other motors.

IMO in most applications water/coolant is cheaper and works just as well. In very extreme situations waterless coolant can have some advantages. Such as the reduced localised boiling ect. Not just in the heads as I've cured an issue of a hot spot in rad due to a very close turbo housing previously. Or in a 3SGTE turbo MR2 they commonly gurgle a bit after a hard thrash in the cylinder heads didn't happen with waterless.

When I used it in my kit car with a supercharged 4AGE the motor was always lets say calm after hard thrashes. no tinking or settling like I could get on water/coolant with heat soak.

Plus it's non-toxic, runs at lower pressures and less harmful to tarmac if spilt I believe.

I tend not to use it when tinkering with my latest project until it's a more stable state as accident spillage gets expensive

I have been thinking of using this product in my car, its does read very well and runs at virtually zero pressure, which is very good, if you was to spring a leak for any reason you don't suddenly expel the coolant which could prove expensive, which is a good safety factor, but as yet not tried it.

I looked at it , insurance don't like it and it catches fire plus cost , I'm not getting it now lol

How interesting - catches fire - I will check with my insurance co before I do this then

I thought normal anti freeze could be dangerous

The waterless coolant is non toxic but is very flammable.

Wow not good having a flammable substance cooling an engine with parts reaching 500 dec c

Waste of money & time had no real advantages over normal coolant but has plenty if disadvantages

I had this stuff in my Cavalier Turbo and to be honest it was brilliant...until you either got a leak or for some reason needed a top up/refill, possibly the most expensive and time consuming mess around I've ever encountered.
