    Waterless Coolant.

    I have always used Evans Waterless Coolant in my Stag after rebuilding engine 6 yrs ago, no problems, but temperature control is a bit sensitive. No engine fan.

    But reading Grampian Stags report on Waterless, it does not seem to be of any benefit, in fact perhaps no benefits particularly through radiator cooling.

    I have a Evans Craig EWP, EJWard Header tank,(inherited) and new super alloy radiator and electric fan controlled by EWP. (And Secret Spoiler!)

    Thinking of trying back to water (with a/freeze)

    Anybody else with experience of Waterless?

    As always there are 2 schools of thought on this.

    There's the ancedotal singular response "well I've used it for 5 years and had no problems response " and then the...Engines can run 45-60°C hotter (at the cylinder heads) with Waterless products. ...Damn just what I want with a Stag...not at all ! response.
    Many Rolling roads where cars performance is optimised will not accept cars with Evans waterless because although the car seems to be ok when run up and the temp gauge may say the engine temp is ok, the engine itself says it isn't, exhibitting pinking or showing signs of distress which says to experienced rolling road operators "It's about to blow"with major components compromised...head or block.
    Think about it, rolling roads whose very existence depends upon saying "yes we''ll tune or set up your car" and will accept Isetta Goggomobiles and Triumph Herald 13/60 as being suitable and robust enough cars to expose to a work out on a rolling road will say "NO" if your car has Evans in it, there's gotta be a real question mark there.
    Why are you thinking of going back to water ? the information described here from Grampian and other sources has been available for nearly 10 years, you now obviously seem unhappy with the Evans but with no real symptoms other than it's "a liitle temperature sensitive". Water and Blue antifreeze is my chosen cooling agent (not even OAT antifreeze) and I have no doubt it's the best overall cooling system for my car that I've been exposed to. However, your car, your choice.

      Davis Craig do not recommend using waterless coolant with their pumps as it is too viscous. Clearly you have not had a problem for 6 years and you are now out of warranty with the pump. But it may have caused some damage hence your temperature control issues?

      But apart from the rediculous price for waterless coolant, it is also highly flammable and should you have a leak, you may not get an early warning as it would not initially show as there would be no steam.

      As Micky says, there are always several schools of thought on these aftermarket "improvements". It's worked so far for you so it is up to you. But blue anti freeze is a lot cheaper, does the job efficiently and should prolong the life of your EWP.

        Davies Craig's advice is equally appropriate to the pump on the Stag. We all know that the jackshaft drive is not as robust as it might be, so increasing the load on the gears by increasing the viscosity of the coolant sounds a bad move to me. I also know owners who have had to (expensively) dump the waterless stuff as their cars overheated badly in hot driving conditions in France. Reverting to conventional antifreeze on the spot immediately cured the problem.

          Evans waterless coolant is great, for the profitability of the manufacturers & sellers. After that not great at all.
          There are 2 secrets to staying on top :- 1. Don't give everything away.

            Well, i decided to remove the Waterless and refill with Antifreeze mix. (flushed out well)

            Result...runs much cooler and not so quick to over heat when stopped in traffic. Used to increase in temperature quickly when stopped, now can stop on tickover for 20 mins and no problem. Used the waterless for about 6 yrs, wont go back to it now!

              Thanks for sharing this. All too often someone will justify using a product because "it cost a lot, so must be better". It takes an honest man to admit that maybe the expensive option isn't quite what it is hyped up to be.

                I think this is the first case of a Stag being switched back to water that I have heard of.

                I have come across this on the TR register forum and seem to remember similar results occurring.

                Thanks again for sharing this.

                  Strange but true....never thought i would do this before i read Grampian Stags assesment . Their findings seem logical.

                  The coolant i took out look good as new. Anybody want some second hand Evans?

                  It is a good product for maybe some other cars suit it better. Probably mine with EWP controlling the Electric fan not the ideal setup.

                    IMHO, this stuff is a solution looking for a problem. It does not conduct heat as well as water, it flows worse than water and puts high loads on pumps and pump drives, it is flammable, (hence banned from drag and race tracks) and will let your engine get up to stupidly high temperatures if there is a cooling fault because there is no tell-tale, aka "steam".

                    All this was discussed on US forums quite a while before the stuff became available here. But I am the first to acknowledge that not everyone reads everything, and so it continues to be marketed and sold.
                    Header tanks - you can't beat a bit of bling.
