    On the TR-6 Wheeler Dealers episode this week, the cooling system was flushed and refilled with Evans NPG+. Has anyone had experience with this stuff?

    I know alot of turbo diesel guys that use it. Great stuff. Not sure if I would run it in my MCS and my reasoning is the MINI is a BMW and will have cooling issues.

    :cornut: There was a whole thread on 'Waterless Cooling' here on MA several years ago. I can't find it but I remember it. Maybe 'Metalman', our tech guru can find it.:Thumbsup:

    OK then, thanks Nathan, you can send this thread out with the next load to the dumpster if you wish. I'll discuss this issue with my independent shop guy next time I'm in and see does he want to bother.

    Alright I'll let the cat out of the bag and actually admit I sell NPG+ here at work. I have never sold it to a BMW or MINI customer. It's always a diesel truck or musclecar or big turbo'd JDM guy that buys NPG+. I wanted to put it in my MCS but my experience with BMWs is that they have coolant leaks. Which I've had with this car. So I didn't swap it over. But from what I've heard from customers and friends that use it, it's awesome. The motor runs cooler.

    I've been running it in my track VW for about 7 years and I had loweer ECT temps by 7-10 degrees - I monitored through the engine management system (not factory ECU). I have been running it in my R53 MCS for the past 5 years - and have no complaints.

    I watched that episode of WD last night too, and that was the first I'd ever heard of that stuff.

    The part that was interesting to me was the part about getting every drop of water out of the system before you put the other stuff in, and the length's he went thru to do that. He said that could take as much as a week of filling and refilling the system. Wow.

    But that was pretty cool when he took the radiator cap off under full temp and there was no pressure release.

    So, what is this stuff exactly, and if you decided to go back to water/glycol mix, what steps would you have to take?

    Did that episode have any influence upon your preconcieved notions about the TR-6? The Lucas fuel pump fail got a laugh out of me (My very first car was a '64 TR Spitfire).
    (Maybe we can get some further value out of this thread)

    NPG+ Waterless Coolant Installation Instructions

    1. Remove radiator drain plug or lower radiator hose at the radiator nipple. Drain fluid into catch pan.

    2. Remove engine block drain plug. Drain fluid into catch pan.

    3. Remove thermostat. This will allow coolant in the upper engine to drain.

    4. Disconnect at least one end of each coolant hose that you can access, and allow coolant to drain.

    5. Remove one of the heater hoses that runs through the firewall to the heater core. Allow the fluid to drain.

    If you have compressed air (or a tube that you can slide over the nipple, to blow through), gently blow
    through the water pipe and heater core (use low pressure–20psi or less). You must have the heater controls
    set to full hot. On electrically controlled models, the key must be in the “RUN” position.

    6. Install the thermostat housing (without the thermostat, if possible). Don’t worry about using a new gasket,
    at this point. Replace all drain plugs and all hoses that were removed or disconnected.

    7. Fill the system with water and run the engine. Keep heater set to full hot. If the thermostat is in place, run
    the engine until full operating temperature is reached. You can leave the radiator/reservoir cap off during
    this step. This will keep the system from building pressure as the coolant warms up.

    8. Allow engine and coolant to cool a bit and repeat Steps 1 through 4.

    9. Reconnect all hoses. Install all drain plugs. Install thermostat with new gasket or o-ring.

    10. Fill cooling system with NPG+. Start engine and follow standard cooling system bleeding process as outlined in the appropriate repair manual.

    These are the NPG+ Instructions my work wrote up.

    Thanks for the detailed write-up.

    Lost me at #3 though. Reminds me a little of the instructions on how to cook a carp on a board. After all the instructions are followed, you throw away the carp and eat the board.

    Probably referring to an old BMW. Like a 2002 or e30.

    Yeah, removing the t-stat on a MINI is not fun, and it's even more complex on 2nd gen cars .....I think I'd go ahead and buy that flush stuff from them and use that.

    So I assume you just add more NPG to make up any losses?

    They don't say what it is, I wouldn't put anything in my car unless I knew what is in it!

    Q. What is Evans Waterless Coolant made of?
    A. Evans Waterless Coolant is a patented non-toxic liquid comprising of blended heat transfer fluids and a proprietary inhibitor package

    That just screams "snake oil" to me!

    Do you know what is in the oil you use, how about the coolant?

    There is enough info on the product out there that should satisfy any skeptic on it's use, I just don't have enough experience on the MINI to satisfy me.

    Yes, I have a very good idea of what's in my motor oil and coolant.

    They're not saying what's in their stuff, there isn't enough info for me.

    This skeptic is far from satisfied.

    It's still snake oil, as far as I'm concerned.

    Honest skepticism plus too many mechanical hoops to jump thru is rapidly making this a dead issue for a growing group of critical MINI owners, especially this one.
