Evans Waterless Coolant


Water – great for drinking but not ideal for engine cooling!

First used in engines some 100 years ago, water-based coolants are universally acknowledged to have inherent physical and chemical limitations that affect long-term reliability, increase maintenance costs and often restrict engine performance.

Like many innovative products that decide the ‘norm’ isn’t necessarily the best way of doing things, Evans Waterless Coolant is possibly a product you’re not familiar with. For those who don’t watch Wheeler Dealers on Discovery channel, it was featured a couple of series ago during their Triumph TR6 overhaul. Ed China is clearly a fan:

In a nutshell, then?

In a nutshell, Evans Waterless Coolant is a revolutionary product when it comes to cooling systems. Rather than mix a coolant with water to fill your car’s cooling system, Evans Waterless Coolant is a product you apply neat to the cooling system, just as you would oil to the engine. There is no water in the product, at all, and if you convert the car correctly, no more water in your cooling system. “But water works, water cools the engine down and has done for a century!” We hear you say. “Why reinvent the wheel?”

Well, just because something is common practice, it doesn’t make it the best solution:

  • Water boils at 100 degrees C, close to the operating temp of most engines. If your engine creeps up to between 100 and 110 degrees C in traffic one day, you’re going to have a bad time. Evans Waterless Coolant has a boiling point of 180 degrees C, far higher than your engine will reach. You could drive around at 120 degrees C, all day long.
  • Water contains oxygen. This means corrosion. Evans Waterless Coolant contains no water, so no corrosion. It doesn’t remove existing corrosion, or restore rusted metal (because no coolant does), but it does remove the origin of the corrosion completely, meaning from the minute you install it, no more corrosion will appear (provided you’ve converted the car correctly).
  • Because the boiling point of Evans Coolant is so much higher than the temperature a engine will run at, the coolant is far more stable at the regular normal running temps than water-based coolants, which, at around 90 degrees C, are becoming all angry and volatile. This is what causes the cooling system to pressurise, and your coolant hoses to swell slightly. With Evans Coolant, the liquid is completely stable at 100 degrees C, meaning your hoses are still soft, your gaskets have no strain on them, you’re far less likely to spring a leak somewhere, and you’re fully able to do this:

(The above test was carried out with the car at full operating temperature, at full throttle on a power run on our rolling road dyno. It demonstrates the lack of pressure, and therefore the absence of water in the cooling system. We do not recommend trying this at home, even if you do have a rolling road dyno in your living room) 
  • The freezing point of water (as we all know) is 0 degrees C. This can be stretched using antifreezes and coolants down to around -20 degrees C, but the disadvantage to this is that the antifreezes can lose their inhibitors after 2-5 years (depending on grade), so you slowly return to that ‘zero’ figure. The freezing point of Evans Waterless Coolant, is -40 degrees C. That’s permanent.
  • What’s also permanent, is the coolant itself. Antifreeze needs changing every 2-5 years, whereas Evans Waterless Coolant will last the lifetime of the engine, provided it isn’t contaminated with water or chemicals. You could run a car for three years using Evans Waterless Coolant, and having decided to sell that particular car, drain it and then convert your new car to accept that same fluid! So while it may cost more than regular antifreeze initially, that cost is usually dissolved within 3-5 major services.

So what does it cost?

There are two ways of converting your car to run Evans Waterless Coolant. This first is to convert your car yourself, at home. The second is to bring it to an approved conversion centre, such as ourselves who can convert it for you.

The prices are as follows (fully inclusive of VAT @ 20%):

You can convert your pride & joy yourself. We are able to supply you instructions, and the product specification and quantity you need. For all conversions, you will need the correct quantity of both prep fluid (unless you have prep fluid you have used and kept previously) and coolant. The amount of coolant required depends entirely on your car’s cooling system capacity. We have databases with most cars’ specifications listed – please contact us for further details.

Prep fluid 2L: £15.99  

Prep fluid 5L: £39.95  

Waterless Coolant (all specifications) 2L: £29.95

Waterless Coolant (all specifications) 5L: £64.95  

All prices include VAT at 20%. We are delighted to offer an additional 5% discount to all current TVR Car Club members, and members of the armed-forces.

We are also able to convert your vehicle to waterless coolant for you. Simply price-up the coolant required for your vehicle from the details above (we do have some specifications to hand covering most cars, if you’re not sure) and allow £59.99 labour (incl. VAT) for the conversion cost. We also offer a 10% off of the above costs of the coolant for any vehicles we convert.
