So what did you do with your truck today?

The adjustable ones will have a jam nut in the rod about 1.5" from where it connects to the pedal arm.

Put the air bags back on my rear axle, painted the axle hubs so they dont look so rusty, then put the camper on the truck.

Now that's stable baby

So I bought this oil cooler a little while ago that I told you all about. I was nervous about installing it on blind faith so I built this rig. It is 1/8 × 3 inch plate. (I would us 1/4 if I did it again).

Then I used some fel-pro gasket material and traced some gasket to use on this tester

Worked out the hole placement and taped in a schader valve

then also thread in a pressure guage.

this is the final product. I am only pressuring the coolant side but any loss of pressure to a leaky oil side would have presented itself by the guage. Looking good so far.

We use similar jigs at work to test oil coolers, usually we pump em up to 90psi, if they hold they good!

we pump em up to 90psi

I was a little leary of putting that much pressure on it since I really did know what it's limits were I ended up at 60 psi and it held that for an hour so hopefully all good. I soaped it up good and no bubbles so on the motor it goes

That should be plenty. Engine coolant psi is supposed to be 13 psi I think, maybe 14 I don’t remember for sure. 7 psi rad caps exist too, so 60 psi on the coolant side should be more than the oil side will ever really have, these engines have pretty low oil pressure in the greater scheme of things…

Also take into consideration what the oil pressure when cold and at rated speed is, its pretty high, thats why the test pressure is high.
60psi with no leaks for an hour I'm willing to bet it is fine too.

I’m initially trying a 32lb radiator cap on project stress test

Interesting… due to the smaller car radiator? Try to keep the pressure higher to keep the boiling point higher?

Are you required to run straight water or something?

Yes straight water and I looped the system no radiator. You got it on higher boiling point.

I’ll post some pics tomorrow.

@DougBoy66 & @Nero & some you others look at my thread I posted back in 2018 Oil Cooler Rebuild Boo-Boo, About starting with post #11 I show a test plate I built and later where I got the directions.

May I ask how well you can go with that camper on there? I have an E350 ambulance 2 years newer and non turbo.....

It handles like a dream. With just an ambunalce body I imagine yours would weigh less

Interesting. Mine has some body roll and slap when cornering, but I am also interested in how your acceleration and performance on hills is.
