[Healeys] Evans Waterless Coolant

[Earl Kagna]

Bruce:

My experience with Evans coolant:  We decided to install it after the engine was completely rebuilt in conjunction with a full restoration.  (BJ8).  We felt that it was an opportune time to do it was with a completely dry cooling system..  So naturally what happened within the first 200 miles – a failed lower rad hose – brand new, and a kevlar one at that.  Not the coolant’s fault, but it illustrated an important objection to the stuff – the cost of replacing the amount that was lost, approx. half, which I did.

Ran it until a couple of months ago when we had to get into the engine again to make some ‘corrections’, so about 4 years total.  I decided to go back to regular antifreeze / water coolant.  (I used the less toxic polypropylene stuff).  The Evans has to be thoroughly cleaned out of the system with a good proper flush when doing this.

The engine ran fine with the Evans in it – no overheating problems, no bad smells, no difficulties.  The big advantage is that it simply won’t boil, even if it gets very hot.  In my opinion, he best thing that can be done for a big Healey cooling system is to use a more efficient radiator core – either re-core an original radiator, or get a new aluminum radiator – I’m told that the Wizard works very well by people who know Healeys.

My advice – stay with regular coolant, the Evans simply isn’t worth it.
