I guess I should know, but don’t…..What is the proper grounding method for the aluminum radiator if one does not have steel lines going from the radiator to the transmission?

John,
I'm surprised no one has mentioned that the radiator is grounded to the engine via the transmission oil cooler lines

I'd take a piece of grounding strap, hook one end to the frame bolts and the other to one of the cooling adaptors, or any place on the radiator with a fitting you can stick it under.
And this sends me back to the new used coach to check. Miguel fitted the aluminum radiator, so I'm sure it's grounded. But it dioesn't hurt to look and confirm.

Johnny,
The radiator should be grounded to the engine / transmission NOT the frame.

Jerry,
I would suggest stripping the insulation off a piece of wire 1 1/2" and sticking it under between the large hose and aluminum
radiator tube at the bottom of the aluminum radiator. Tighten the screw clamp. Tie wrap that wire to the hose as it runs to the
water pump. Crimp a connector to the end of that wire and connect it to one of the water pump retaining bolts. Fire up the engine
and make sure it there aren't any leaks.
Regards,
Rob M.

I usually agree with Rob. Not this time.
Given that the chassis and engine block are currently connect with a heavy strap, they are at the same potential. Consequently, using the radiator frame as a ground will work quite well. Sticking a wire under a hose is, to me, a recipe for early failure of the hose as well as a potential leak, due to unequal pressure on the hose. If you're determined to do this, however, use the top hose - some coolant will remain in the system even if a leak appears. A leak at the lower hose outlet, being the lowest place in the system, will drain it entirely.
n.b. If your coach doesn't have a good ground run between the frame and the engine/transmission, put one. A lack of a good connection will result in strange stray currents, some of which have the potential to Break Things.
