Evans waterless coolant.

Hi Spike, I've heard of it. and reviews of it in MG owner and Practical classics magazines have suggested that it does what it says on the tin, but...

It means, as far as I can see, that if you have a leak, split hose, any little thing you can't top it up with water which is a bit of a problem if you're on holiday or on a trip and loosing a pint a day.   And, of course, it's rather expensive.   I came to the conclusion that I was better off using clean water, good anti freeze and changing it every three years.

But that's only my opinion, others might well disagree.

I've just read the discourse on PH. I think I'll stick with good old H2O, I'm not sure our cooling systems were designed with flammable liquids in mind.

Furthermore, I declare that I have no first hand experience of this product.

My overview is it is an undoubtedly a good product but not one necessarily essential considering the cost of application. I accept and understand claims made that, it makes for better cooling and has better non corrosive properties. These are the two qualities I can identify with most.

By my understanding of all other claimed advantages are insignificant as they offer superiority in the extremes of cooling failure. Currently, given adequate cooling on engines in the conventional system is sufficient in the UK climate, terrain, driving conditions and driving purpose. Naturally, maintaining regular schedule for renewal of conventional coolants as per manufacturers instructions is important.

My considerations may differ if conditions and application were changed, like driving in mountainous, tropical regions hauling heavy loads. I see other advantages mainly for Diesel fleet haulers. 

Conversion to the waterless cooling (wl/c) requires for complete drainage of the cooling system even by means of jacking the vehicle to raise or lower for drainage and even low pressure air line use.

A preparation fluid is then added to the cooling system to absorb all water and moisture from the cooling system, running the engine so the hygroscopic (moisture absorbing) mixture can do its deed. After further drainage, it is a matter of replenishing with one of the four types of wl/c's suitable for your vehicle.

Leaving a side labour charges the cost breakdown for the product is as follows:

Preparation fluid - 5 Lts, £35 Only enough Preparation fluid is needed to be able to run the system up to temperature for around 20-25 minutes, normally recommended is three quarters full.
Evans Classic Cool 180 ...£29.94 rimmerbros.c. 
Evans Power Cool 180°..£64.95 eBay

These products are available in 2 litre and 5 litre containers.

5 litres waterless coolant RRP is £64.95

2 litres Prep Fluid RRP is £15.99

5 litres Prep Fluid RRP is £39.95  (Nathan Evans Cooling UK)

I had put some questions to Nathan Evans Cooling UK which they kindly answered back; amongst which was the one not seen to be asked in their FAQs section regarding effects on silicone hose use with wl/c.

Their reply, "Our products have been tested extensively and have ASTM accreditation in the U.S. Samco are currently running their own tests against silicone hoses and all looks great so far. We have only done this so that we have references here in the UK. We have converted thousands of vehicles with silicone hoses and nothing detrimental has or will occur with these components".

Note the G-Wagen cooling system for the W460s and W463 upto 300GE/D (not including the more latter models like 320CDI, 400 CDI and 500s) takes around 11.5 Litres, so the prices shown have to be doubled. Is spending over £215 plus VAT going to be worth it?

I do not know but one of our club members was to have a meeting in becoming a distributor of this product; not knowing if he has signed up or not but contact Kevinstuttgart on www.stuttgartgarage.co.uk based in South Wales.
