90 3.1 coolant bleed

[Bengal0815]

My father,uncle, and myself just spent 3 days swapping a 3.1 with 100,000 into a car that had 270,000. Starts and sounds smooth but my father and I are having 2 problems. The first is that the chilton book refers to the manual for the "proper" way to bleed the coolant. It must be referring to a later model manual becasue i've read the 1990 manual cover to cover with no luck. I was wondering if anyone knew the "proper" way to bleed the system. Also the starter is staying engaged even after the ignition is turned off and the key removed. We pulled the starter again and took it apart with no apparent problems. Our next guess is the ignition swtich but if anyone has any other theories they would be greatly appreciated. Can't wait to get this baby on the road!

For the coolant bleed: Fill your radiator and your coolant reservoir. open the bleed screws and let the car reach operating temp. when your bleed screws shoot a solid stream of coolant (not bubbling), the air should be out of the system. your bleed screws should be: one near the thermostat housing and one in the heater line leading to the heater core.

the starter thing sounds like when I swapped a 350 into my Toronado. I know you said you already dismantled the starter, but examine the drive gear pinion. Mine did the same thing and it turns out that I had missed a few shims on my starter housing, and upon examining the starter I found a small groove worn into the shaft that was actually keeping the starter teeth engaged in the flywheel and it was also keeping the solenoid energized, I had to unhook the battery to make the starter stop spinning.
