    I would always run with coolant may help clean it up over a period of time ?

    Always use antifreeze as it's also a corrosion inhibitor. Antifreeze also keeps any rust moving so it doesn't settle in the rad and block it. 50/50 mix will aid cooling as well.

    Give it a few good flushes with Rad flusher then do as Kev says.

    When I've had this in the past, I've connected the hose pipe up to the engine and forced water through in the opposite direction it would normally go.
    A lot of the crud will get dislodged. You should then use the appropriate type of coolant as mentioned above.

    Just for information, I think you'll find 'coolant' is a bit of a misnomer (I looked into all this a while back when I had a bike that was very marginal on cooling). The very best for heat dissipation is plain old pure water (with the possible exception of 'water wetter' to break the surface tension down, but a couple of drops of soap would do the same thing). Adding 'coolant' actually decreases the cooling effect (although only slightly), but does help with anti-corrosion (and could be said to help lube the pump as well). Coolant (ie anti-freeze), does give the necessary protection from icing, and also increases the boiling point (although if you've got boiling problems you really need to locate and fix the problem at source).

    That's my background Odgie , 15 years in the car radiator trade ,and antifreeze definitely drops running temperature , even conducted tests with hand held laser thermometer to back up incar gauge.It makes at least 5C and up to 10c difference over plain water.

    Now whether that would be the case on an unpressurised system I don't know, never had the call to check it out

    Water wetter makes a 10-15C drop though never tried the 2 together. I try to make sure the rad is speced to cool well without aids.


    Boiling is a relative term ,I prefer' overheating' as different cars have different requirements and modern cars run at very high temps that we wouldn't be happy with in older motors.

    If you check back in tech section ( seach 'overheating' ) on the NSRA site you'll see a thread by Klunk where we worked together to impove the cooling on his Rover and he shows what difference each step made in his application.

    IIRC pure water is better than pure antifreeze, but mixed together 50/50 the heat capacity and cooling effect of mix is way better.

    Biggest mistake I ever made was to drain-off the water on a laid-up car through winter so it wouldn't feeze-up. The core plugs just rusted-out so the next time I used it thay just burst through. The amount of rust scale in the block created later issues
