I'm trying to drain the coolant to change temperature sensor, sender and thermostat. I have unscrewed the petcock almost an inch and only getting drops of coolant. It won't unscrew anymore. Any suggestions?

Remove the lower hose and let it gush out there.

It has to drain down some.

Look at where they are on a 4.6, they’re at the highest point in the cooling system, just higher than the full/cold mark on the reservoir. There will be some coolant in the upper hose but as long as you tilt it up very little if any coolant will spill out, and none will erupt out from the crossover. I’ve done both before

Those are both the same pulley; you don't have to buy the whole tensioner.

I was surprised they sold it that way, personally.
