    Default Oil Cooler with Thermasat

    Have any of you guys used a oil cooler with a thermostat? I got one and after installing the t-stat it scared the heck out of me. I have #12 lines from block to filer head, then to proposed cooler per Teague direction and then my oil cooler has 3/4" inlets for oil. Anyways it looks like the cooler is so restrictive it would be counter productive. So hopefully someone knows about these thing and makes me feel better. Thanks

    I know it has to be somewhat restrictive so it has enough time to pull the heat

    Default Not needed...

    From my experience you don't need a thermostat to build oil temperature.. Maybe in a diesel truck in super cold climate, but once you start building Rs in a boat the oil temp comes up very quickly. Are you worried your oil is running too cold?? I tell pleasure boaters to be sure and warm the engine, and oil, before stomping on the throttle...

    I am super worried about too hot of oil, mine gets insane hot ( over 270 ) but when I shopped for a cooler for my new engine this guy sold me on the one I got because he said too cold of oil is just as bad. I should have got a normal cooler but here I am now and I power-coated it so I cant even return it. I called them ( Mr. Cool ) and he swears the opening is big enough but I really cant see how.

    Default oil temperatures

    Organic oil does not start to break down until 284 degrees Fahrenheit. I've ran Mobil 1 up to 340 Fahrenheit for a couple hours sustained and it was fine.

    Are you worried about the flow of oil or the flow of water?

    I've got a hydraulic Oil cooler off a Tamrock Axera rock drill and going to put it on the boat this year.
    It looks similar size as yours.
    I was going to use a mercuiser thermostat and housing to regulate the temp tho.
    I'm still haven't figured how to retrofit a overflow bottle.

    The oil that was ran through the one I got ran at a constant 104 degrees fahrenheit without any thermostat at about 10bar water pressure and had a overtemp cutout at 190, which only happened if you only had below 5 bar water pressure after a few hours of heavy use.

    Apparently they work well in a boat.

    My original boat was only running 3/4 right through from pump to exhaust.
