    Putting a thermostat in the Riva open loop kit...I have some ideas. Opinions welcome.

    My ski is a fully built Ď17 300px/142 wheel. Last year was an absolute headache trying to get my ski to run a consistent temperature. The water is much cooler up north and I donít feel like dealing with that this year. Here is what Iíve come up with on how to utilize a thermostat and run the open loop system. All hoses will be 3/4Ē. The water goes through the back of the intercooler directly off the pump and in the front of my cooler(fizzle) the top will go through the normal routing to the engine and the bottom port will dump out the back and be used as a pressure relief until the thermostat opens up. Iíll be running a control valve in between the line drawn in red.

    The thermostat has 3 small holes drilled in it so it will always be flowing something with a majority of the water going out of the intercooler until the Tstat opens up. I will be running a 3/4Ē barbed flow valve to vary the amount of water coming out of the secondary dump on the intercooler. It would be open more in the colder weather and less in the summer months.

    With the way Iím hoping to set it up, the ski will have to idle until completely warm to prevent over pressure of the system.


    Thoughts/revisions?

    I also live in CT and used this routing successfully with a green pump restrictor.

    Explain. Did you add another hole to the front cover?
