    Heat Exchanger Pump Washer Set Up

    I am going to be taking the open loop of my ski in the next few weeks and fitting a heat exchanger set up. Question is do I now go back to the OEM washer in the pump outlet for the intercooler and exhaust cooling or do I keep the larger open loop washer in there?

    Yes, go back to your complete setup before you went open loop...

    Don't forget, when you put the coolant back in, you will have to "burp" the system a few times, by squeezing the hose that goes from the head to the thermo sveral times to move the coolant back and forth. This will get most of the air bubbles out....Fill the coolant bottle, when it levels off, BURP the hose...Depending on where you mount the HX, you will only need about 1 gallon of coolant....Then top it off after a run.

    Saw several guys mount the HX like I did on mine in this picture.
    I didn't really think of the air caught inside the HX. But after a run and some jumping I guess most of it would come out?

    Air on coolant side no it's a sealed pressurized system you can bounce that like a ball as long as you don't spring a leak. If your getting air in your coolant side your not holding pressure. The bleed your referring to is a pressure relief if you don't have that you will swell that intercooler like a balloon.

    That is mounted wrong.....the fittings need to point UP to vent any air in the system....I suggest finding a new place to mount it...
