Well with all that was going on this fall with my Fathers health I think i made a costly mistake. I was out in the barn both my egines are on stands waiting for rebuilds. When I pulled them I pulled the block plugs and the manifold hoses off and drained the motors what I thought was complete....well I left the rear hose on the oil coolers.....the water pused the back caps right off slick as a whistel. Can they be put back together or are they shot? They dont look like they were braised maybe just pressed together?????anyone?

They can usually be solder right back on, no problem

Make sure to test them before running your engines. It's possible they were damaged internally.

I hope so......

Well I can go a step further. I did the same thing, then replaced the cooler and reversed the oil lines
20 hours later the knock in the engine started

Dyno,
I did the same thing one year... I just soldered it back on.. but you can take it to a local radiator shop and have them solder and psi test it.. I am sure they could handle it. I would think 40psi on the water side and 90psi on the oil side would tell you if it is still good. I later took the steering part off and soldered the cap from the cooler on to the small section (two section cooler) and replaced the big part with a bigger part and kept the small part for the steering.. still using it today!
Hope that helps
Dick

Go to your room!

dyno,

What do your coolers look like? I have some HP500 oil/powersteering coolers that mount to the rear bellhousing with intake on the bottom starboard/outlet on top port I'm taking off my motors. Let me know if you need these.

Chris yours may be an upgrade what do you want for them?

I believe I paid around $400 each a few years ago. I have no thermostatic controls and Sterling thinks they are too big ... I was probably running too cold. I want to make sure they will work for you and if so, I will give you a really good deal, my friend. CAll me @ 419-882-1680 or I will try you later after I get up this afternoon. Night shift sucks!
