N14 oil cooler

so the little thing that turns the water off and on is replaceable without replacing the whole part....that's good to know the 1 on my freightliner dump wouldn't turn and it just snapped off ..leaked a little til I put some sealer on it until I got to a salvage yard to replace the whole thing..

 

All coolant needs to be tested and the aditive package replenished over time.
The valve is easy to change you have to drill it out, I used a 5/16 lag screw, and drilled it to 1/4 inch, Then used a slide hammer. Once in a while it would strip out and I would then use a 3/8.
Just a thought!

 

I have coolant going into oil need help what can it be
