Anyone know the location of the heater bleed screw on a late model 360? Have searched the engine bay but can't find anything, could it be in the dash? That doesn't seem practice. No heater since a coolant leak I think it's airlocked. Haynes Manual shows one but can't find it.

There wasn't one on my 87 360. It should self bleed, maybe blocked with sediment. Disconnect the pipes to the engine and reverse flush with a hose.
