Subject: Re: Waterless Coolant
Just to resurrect this thread once again about waterless coolants and the like ...
There have also been other comments elsewhere on this Forum.
Maybe it is worth reading and noting Jonathan Oppenheimer comments in the February Newsletter (just received) about his experiences with "4 Life Coolant". I do not know the product specifically or the circumstances in which it was used but it would appear to be one of the so called "waterless coolant" varieties.
In my humble opinion do NOT use these products in our old fashioned engines or be prepared for trouble.
If you do use them be prepared for localised overheating of which you will not be aware. This can cause pistons to seize and other problems.
Your temperature gauge (if accurate) only tells you the temperature in the header tank and not elsewhere in the engine.
I was assured by a very well qualified modern automotive cooling engineer (working for a large well know car company) that nothing is better than ordinary water for cooling - although maybe add a little antifreeze/corrosion protection.
Any alternatives views,experiences or comments welcome !

I have a 14/60 HC, and there is no cooling fan. I propose to fit an electric fan to assist the cooling, and should be grateful for advice as to what make/model/type to fit. I am a little impecunious and need to spend as little as possible.

If you have had your radiator re-cored and the block has been cleaned of all sludge it is almost certain you will not need a fan. In fact the majority of 14/60 and 2 Litre cars do not have one fitted. The Lagonda radiator with water pump is very efficient. The normal running temperature is 70C. My car sits at a steady 70C unless it is a very hot day or I am stuck in traffic and even then it does not boil.
As for waterless coolant, I would never touch the stuff, too many issues have arisen with different vintage engines that are well documented

Hi Steve

Just to add to Mark's wise words, check whether you have a thermostat. If you don't have one you will need to fit one. The thermostat diverts the coolant from the bypass which is at the side of the radiator, and opens the flow to down the honeycomb.

Also check that the water pump impeller is going round. It is riveted to the shaft and I have known for these to dissolve.

You may need to descale the radiator using Fernox DS3 .
