Waterless Coolant; Has anyone tried this?

I came across a video on Youtube swearing on Evans Waterless coolant for older cars, has anyone tried this in a '3b?

The water in my 54 radiator is coming out yellow so I'm tempted to try this stuff.

Has anyone else tried it?

Was it any good?

What would we have to change the thermostat to and radiator cap to?

All opinions welcome!

Spacecrab,
I'd never heard of this stuff until you posted it. I'm not sure how it would work with an older engine. I've read the information on the website and it seems that, at least specifically for diesels, you have to change out the thermostat and the auxiliary fan sensors to allow the engine to run at a higher temp.

I'm no scientist so I'm not sure about this. I know a lot of variables go into making an engine run efficiently but I'd be skeptical of running my engine at a “normal” increase in temperature.

Right off the bat, it seems this is designed for hard working equipment, i.e. heavy diesels, racing, aircraft, etc. I did find a statement where it is not designed for daily drivers or cold weather operations. It did specify it doesn’t corrode or suffer from electrolysis - that's good.

I notice there is a list of conversion centers. Perhaps it would help to call and ask specific questions on older engines and see how their warranty would work with older equipment that’s no longer manufactured.

Another thing I notice is the price.

Corrosion and electrolysis effects can be avoided if you use distilled water and change your coolant every two years.

Hi Rus,

It does seem their main market is big diesel rigs and high performance but the one which interested me was the Vintage Cool 180

They claim it lasts the lifetime of the engine,... but I have to admit that "normal increase" in temperature sounds strange.

Well, this stuff does sound interesting. But 65 british pounds converts for me to $105 for 5 quarts. I guess guys like Jay Leno can afford that.

They have a product called "Classic" for engines made in the 50' and 60's. It is not cheap plus you have to flush the system with their special additive (38GBP) to get rid of water. No electrolysis on the metal parts is nice, but the price...and you need more than two jugs!

I cant give detailed specifics or tech. info, but..

Many years ago, my mechanic had a couple of rather elderly vehicles (more or less daily drives) that surprised me by how quiet they ran.
You could barely hear any mechanical noise from the engines, even when the bonnet was open.

He told me he was using an industrial "heat exchanger oil" instead of regular coolant- and had for 30+ years.
He had learnt about this stuff with big industrial engines when he did his apprenticeship in the 1940's/50's.
Later he did "unofficial research with light vehicles" using the stuff when working for General Motors Holden at the Lang Lang proving grounds (Australia)

IIRC he had to either bore out the thermostat or replace it with a restrictor of some sort, and reduce the number of blades on the water pump impeller.

No, I couldnt find the courage to grind the impellor blades out of my V6 ford capri's water pump!

I thought about it- but didnt have the need to fiddle with the cooling system as the previous owner had fitted a custom radiator which was much more effective than the original.

However- when working in a large hotel, I discovered our in-house commercial laundry used large quantities of a similar special heat exchanging oil in the machinery.

I wondered at the time if it was the same stuff.

IIRC, my mechanic reckoned it was better if used in machinery that ran over long periods of time- like generator sets, large waterpumps and possibly diesel powered loco's?

might e worth calling a company that supplies these types of oil- and asking them for info regarding its uses.
