I followed the priming instructions in the service manual (turning lock to lock) and there aren't any more air bubbles coming out. It took about a quart to refill the PS system. What makes no sense is that the manual says the system takes 1 1/8 quarts and I've now added a new, somewhat larger cooler. Unless there is some retained fluid from the drain, I don't know why I only fit 1 quart. Annoying...
