Coolant

    Dex Cool is just a general term. Several companies make a Dex Cool product.. i.e. Prestone and others. It is orange and considered extended life.

    When it first came out it wasn't compatible with some other coolants without thickening. Now days it pretty much works with the average coolant, but I still don't mix coolants. You can top off if the reservoir bottle is low with distilled water if you want.

    Hello Roger,
    I want to thank you, you solved my problem.
    I happened upon one of your posts regarding the oil thermostat, you indicated that you were not a fan. My oil temp was running 240F, I removed the thermostat and the temp dropped a solid 20F.

    you probably had air trapped in the system.
    To avoid this fill it very slowly, allowing the air to escape around the trickle of coolant going in.
    Then do a short engine run and refill the system
    you can also squeeze the hoses to burp any air out but air may be trapped in the cooler as well.
