    Flushing problem FZR with R&D cooling upgrade kit

    Hi everyone.
    I will try to explain ... my problem,

    I did install R&D cooling upgrade kit: engine + intercooler.

    I did 3 new holes on the transom.

    2 hose are connected to the pump
    1 hose to the nozze.

    it's ok.

    but...
    on the trailer, when I try to flush my motor,
    with the oem flushing route,
    the water go directly out, in the new hole, and the motor became very hot in few second.

    do I have to install non return valve on the 3 new hose?

    thanks and sorry for my english...

    Ale

    if you reroute to much water to other parts like intercooler or oil cooler its going to happen, remember that the engine has a thermostat and its the highest point where the hot water comes out of the engine, being in the hose ,does not have the same pressure and volume as when its coming from the pump. so most of the water is going back out through your new route and not reaching the head at the volume needed to cool down the engine.

    Yes, thats the problem.
    when on trailer,
    the water I push into the oem flushing circuit, going back out through my new route.
    how can I flush my engine and my intercooler?
    I will try to install no return valve on the 3 new hoses.
    is it correct?

    I installed a ball valve before the 3 way fitting to stop this when I installed my RIVA I/C.
