There are two drains - one at the bottom of the radiator and one on the side of the block near the dip stick hole.
The radiator drain opens but the one off the block is really stuck. I’m worried about making matters worse by forcing it.
So I warmed up the engine slightly and then opened the radiator port and managed to drain out about 3 gallons. Trouble is that according to Bentley total capacity is about 5 gals. I did have the heater set to hot.
Am I missing something?
