    MSX 150 Cooling System

    Is anyone familiar with the closed loop, anti-freeze, side of the engine? I am trying to drain and flush it and add new. Where are the drains located? A service manual would be handy, but after searching for an hour or so I have failed to locate one. Thanks.

    I parted out my 150 not to long ago and I dont rember seeing any drains I also took a look at the parts I still have and could not find one. I will look through the service manual I have and see if there is a suggested way to flush the system.

    77jonboy, would it be possible to get a copy of your service manual? I have been looking high and low and cannot find a pdf.

    Just in case I cant email it this is what the manual said:

    Engine Coolant Change Procedure
    1. Remove the hose that connects the coolant expansion
    tank the water pump cover. The engine coolant will
    drain into the engine compartment bilge.
    2. Re--attach the hose. Open the two hull bilge plugs.
    Place two containers directly under the bilge plugs.
    3. Carefully lift the front of the boat to about 15 degrees
    up. Allow all of the coolant to exit the engine
    compartment.
    4. Flush the bilge with clean water, and secure bilge
    plugs.
    5. Obtain new engine coolant, and slowly fill the
    expansion tank to theMAX mark. Allow the system to
    purge the air out of the circuits. (Level will go down
    over short period of time.)
    6. Repeat process two to three times. Never fill level
    above MAX mark.
    NOTE: The coolant level will drop after the first several operation cycles

    A messy process at best.

    I would/have suck the coolant out of the expansion tank with a vac oil extractor. tilt the ski up to help drain as much coolant out of the oil cooler at the front and keep sucking. You will need to fill up with plain water and dilute what is left and suck it out again. It is impossible to drain all the coolant out of the heat exchanger where it is placed (unless you can get the ski vertical). Leaving traces of coolant is not a problem if you are puttting the same back in but it is advisable to flush well if you are changing brands.

    Cheers

    Mission accomplished, coolant changed. Thanks to 77jonboy. Overall somewhat messy, but not bad. I simply disconnected some intercooler hoses and pushed it out of the way, pulled the air intake off the turbo inlet and presto, decent access. This was nowhere as bad a changing sparkplugs on a Yamaha R1.
