Raised moter (D/side ) one in. Cooler loose. Seems to be interference with removal. Motor mount, exhaust man. steering column ? What do I need to do?

See if this helps:

Per the Ford service tech manual, to remove/install the oil cooler you have to unbolt the engine isolator on the driver's side of the engine. The two bolts are located on the underside of the crossmember, and are a pain to get out. But once those bolts are out, lift the engine with a hoist 1-2 inches and slide a block of wood under the isolator/crossmember (so the engine can't fall). Then just unbolt the oil cooler and maneuver it out the back side of the engine compartment.

Thanks. I just didn't have the motor raised high enough. Be sure to clean the header mating surfaces really good before mounting. Gaskets are thin and WILL leak if not free of old gasket residue.

Good job!

Thanks.
My 92 f250 7.3L w/mechanical injection pump, mechanical fuel pump has a hard time starting. It acts like it's lost prime. I crank for about five seconds at least and the it fires up. It runs fine after that. I replaced the return line O rings so no leaks there. I think it's losing fuel pressure when the engine is off. Where to start looking? I have the 92 Ford manual on disk.
Thanks

It sounds like a worn fuel pump (diaphram goes), which is no longer developing sufficient fuel pressure at cranking speed. Should be easy to test with a fuel pressure gauge. I only recommend genuine Motorcraft fuel pumps, should it need replacing. Also, install a new Motorcraft fuel filter, if it hasn't been changed in the past 12 months. Easy jobs. If the problem persists, focus on the fuel injection pump. If it's the original injection pump, it may be worn too.

I figured it could be the fuel pump. The injection pump isn't that old. Had it changed when it pumped about five gallons of diesel into the crankcase. Every O ring in the fuel system was leaking. (Thank you EPA for low sulphur diesel). I've been adding ATF to the fuel at every fill up since.
What about the shutdown solenoid ? Could that be a problem too?

It's possible, I guess, but they are very reliable. Since it starts after cranking for 5 seconds or so, I would not suspect the shutdown solenoid.

I see some leakage at the fuel pump. Will change it and see if that does it.
Thanks for the advise and the fast responses.
I also have a f350 w/4wd dually auto trans. Want to change the fluid. Type? Mercon SD?

Depending on the year, I would drop and clean the pan and magnet, replace the filter, drain the torque converter (look for and remove the cover plate and drain bolt), and refill with Amsoil Torque-Drive ATF. This is a top-of-the-line Mercon ATF fluid for diesel applications. I only run full synthetic heavy duty engine oil and transmission fluids in the diesels I service. Remember to also change the fluid in the transfer case.
