Evans waterless coolant

[Jonathan Kay]

On manufacturers using it as original coolant:

1 This would have enormous marketing value. Some members of my family used to own Decosol, and getting their products used as part of original equipment was a major objective. Some of you will have bought new cars with packets thrown in.

2 Manufacturers have the capacity to study some of the claimed effects such as reduced local overheating and reduced corrosion.

3 The only example of promotion by a major manufacturer that I can recall for Evans Waterless Coolant was Honda with sone offroad vehicles. That will be in the archives somewhere. IIRC there was the usual lack of evidence. 

4 "Some manufacturers are using Evans like coolants: Mazda is using a long life coolant, able to stand 200.000 km or 11 years for the MX5 NC (FL22 engine). This coolant can't be mixed with another one (like Evans)."

Thanks. I'll have a look.

Mazda FL22 long life coolant is based on ethylene glycol and is supplied premixed as "55% coolant, 45% water".

I'd guess that any difference from traditional coolants is in the inhibitors rather than the bulk coolant.
