Radiator is back in place, still hoses to hook up. Removed the oil cooler adapter and steel lines, the adapter retaining bolt was only finger tight. Explains how dirty the engine is back there.

Big question for you folks, were the trans cooler tubes originally all metal? One is metal, the other had a piece of hose clamped to the tubing right behind the radiator. Both ends of that tube had flares, but no nuts so I'm thinking somebody cut out a section and flared the cut ends to give a better seal on the hose. A new steel line from the radiator to the cut end, and a compression fitting to join the two should do it. The cooler pressure is low enough, a compression fitting should be fine.

Pulled the heater hoses and capped the engine fittings for now. The coach has the lines running back to the water heater, not sure if I'll bother with those since the seller said the hot water heater is disconnected as it leaked. Doubt that many new heaters have a coolant fed preheater. Repaired some 12v ignition wiring, tried to make some sense out of the vacuum hoses. That's going to be a job for later, the ones that are left are all connected, empty connectors are capped off.

Still have to replace the air pressure switch, it sat right where the bolts go to hold the radiator saddle and didn't look healthy. The placement of the switch is really odd, can't imagine why the mounting bracket is welded in place when there's no room to rotate the switch to thread it into the fitting. The plan is to use a 90° fitting to swing it to the driver's side.

All in all, a productive day. Still couldn't run the engine for long, but did put it in gear and feel the trans engage. With luck, next week it moves under it's own power.

Thanks again for everybody's input!
