I can not find the capacity. I put in a new water pump and need to refill.

1 gallon, half and half

Simply fill until it reaches the top of the filler neck... run the engine to burp the system, then top it off. Also top off the reserve tank.

About a gallon. I usually have an empty laying around. I dump the old in it and then I have a good idea if there is an air bubble or not by putting about the same amount back in.
