The 'E' Type Forum

This seems a good product, and has obvious benefits for the E type, (corroding header tanks etc) has anyone tried it?

There was a thread on Jag-Lovers a month or so ago. Have a read and then decide if it's still as good as you think it is.

I did also consider changing but decided not to after reading the Jag-Lovers threads:

This from Mike Frank of Coolcat http://www.coolcatcorp.com/

"1) Pure glycol has a lower specific temperature than water. This means that you may run hotter. The engine may tolerate it, maybe not.

2) In freezing temperature, it's jelly. In very cold temps, it crystalizes. Doesn't expand like water, so you won't crack your block, but the engine will actually run hot until the coolant reliquifies. For modern cars, Evans makes special pump impellers and thermostats to overcome this problem.

3) The biggest issue for me is that it's flammable. Funny how they never mention that. Given that the leak prone transfer pipes run through the inside of the E-Type bulkhead, this is more danger than I care for.

David : I read that but frankly had no idea what the point was which he was making. I do not know what the Evans compound is, but I am quite sure it is not ethylene glycol because there would be no basis for a patent on that ( and the same presumably applies to propylene glycol, which has been used in central heating systems for decades ) . I also think that what he meant was "specific heat" : "Specific temperature" sounds like a meaningless concept to me

It should indeed be 'specific heat' rather than 'specific temperature'. I have no personal experience of Evans Coolant so cannot offer an opinion on its effects but I am not sure I am particularly interested in something that has a life span of 25 years - I doubt I will want to drive an E-Type at that point!

I see reading this months classic car magazine that Quentin Wilson is extolling the virtues of waterless coolant in his early 3.8 FHC. I was wondering about this I know a few Aston restorers are starting to use it and wondered whether the view had changed on this since the last time it was debated. I am sticking with my original cooling system set up with the exception of a new made Marston alloy radiator as mine had been replaced later in its life and a Cool Cats radiator "otter" switch. Could this coolant be worth it?

I ruled it out on cost alone. You first need to fill the car with their special 'preparation' water scavenging fluid (?40 gallon) then refill with the special coolant at ?65/gallon. So about ?300 to do the job and a 24 step process. But with Ed China from Wheeler Dealers and Quentin Wilson doing their paid 'advertorial' who am I to argue.

If it's recommended by Quentin Wilson it tells you all you need to know. I shall stick to normal coolants . Let's face it, 32,000 Merlins ( in Lancasters alone, let alone Halifax, Spitfire, Hurricane, Mosquito etc ) flew Lord knows how many hours on Ethylene Glycol ! ( but then Bomber Harris didn't have Wheeler Dealers or Wilson to advise him )

I've just looked at the latest edition of the club magazine and Evans waterless coolant appears to be endorsed by JD, Eagle, CKL and others in their advert. Are they all wrong or have I misunderstood something?

They don't 'endorse' it, they sell it at a margin.

My advice would be to call Andy at Hutsons.

Then avoid it like the plague.

A good water cooling system needs no help from chemicals.

Buy a new radiator and a good flush........

I should make up your own mind about the correctness or otherwise of endorsements. Personally, I would only rely on endorsements by traders who I have had experience of and whom I know to be reputable

I had a candid conversation with one of their resellers whom I know well and their view was:

1. Yes, it works very well as a coolant
2. No one who has used it has complained about its performance
3. If the engine/radiator has been contaminated with conventional coolant it requires a fill of the Evans 'preparation' fluid before their coolant can be used. This is not made very clear in their advertising but the reseller does do so
4. They are happy to endorse it for the above reasons (along with the fact they make a good profit on it!)

Customers tend to be well heeled types who just expect their classic cars to work rather than knowledgeable enthusiasts for whom maintenance is part of the joy of ownership.

Stuff such as this always seems to me like a solution for an imaginary problem--or a real problem that can be solved with a proper radiator flush or re-core.

Ok chaps. It's a no from me then! I have a new Fosseway Radiator ( no connection with this company ) on its way to me, a new otter switch and a newly rebuilt and flushed engine. I am going to take my chances with Jaguars original set hope that it should sufficient. There is one engine builder I rate more than any other in Classic land and to my knowledge he does not sell or recommend this. That doesn't mean that he has a negative view of it, I genuinely don't know but will ask him. I just think its a bit of a gimmick that is a bit costly and laborious to try out.

I have the same dilemma myself, but the more I think about it the more I have decided to stick with the traditional antifreeze. My concerns are naturally the cost involved (including the extra water repellent to flush out any water from the system first) and the need to always carry some in the boot. Water does not mix with it and so what if the radiator springs a leak when out and about? On the Jaglovers site people have also found that it turns to jelly at very low temperatures so the engine runs hotter than it should until the jelly liquefies.

I'll stick with the tried and tested. I know Jay Leno has it in all of his cars, I know others strongly recommend it, but I'm used to carrying a litre bottle behind the driver's seat against the tunnel for the last 30 years.

Thanks. I have decided to go exactly as standard. It's worked fine for me in any number of vehicles so given the cost and inconvenience I am sticking with H2O!

Is
Porsche,
Ferrari,
Bentley,
Rolls-Royce
or any other producer of expensive vars using the "wonder-liquid". Maybe the ingenieurs (NOT car mechanics or other simple handworking guys) of theses companies can tell very exactly why not.

Found this today, very interesting....
