    Coolant system routing after deleteing Water to Oil cooler?

    Guest-only advertisement. Register or Log In now!
    I deleted my water to oil cooler and replaced it with a thermostatic adapter plate for the sake of simplicity and more cooling. My stock hoses were leaking coolant a bit too.
    My question is how do smaller hoses coming off the thermostat housing and the return line get routed while retaining proper routing for the expansion tank?
    do they get capped ect?

    I just used a plastic elbow to connect both of the oil cooler coolant lines. I didn't want to mess with the flow at all.

    Just attach the 2 coolant hoses together with a straight union barb fitting right where they would have attached to the oil cooler.

    If you cannot do great things, do small things in a great way.

    I wanted to delete all those lines, so i decided to cap the coolant feed line above the oil cooler.
    Im putting a new expansion tank where stock air box is and running the overflow lines from the back of the engine and on the upper rad hose to it.
    Then im running a line from the small port on the tstat housing to the new tank.
    Should retain stock coolant routing design, just in a different spot. Stay tuned for more pics so others doing the same thing know exactly what im talking about.

    It works great. I put in a Setrab oil cooler where my passenger side mount intercooler used to be with -8 lines running to it that i made myself with summit fittings. I got a cheap amazon bubble style coolant expansion tank and put it where my air box is. No leaks and i removed about a thousand feet of coolant hoses.
    The routing is super easy to delete the oil to water cooler.
    The smaller of the two lines comming off the tstat housing goes to the large port on a coolant expansion tank wherever you decide to place it.
    The small line coming off the upper radiator hose and the small line coming off the drivers side cylinder head coolant passage goes to a three way tee and then to the small port on a coolant expansion tank.
    There is a small port right above your AC compressor that will need to be plugged.
    Thats it
    Thanks for reminding me, i will get some pics.
