Changed out a leaky PS pump in a 2001 Durango 4.7 last weekend. I've since spent parts of our evenings trying to burp the system of its air and I'm still getting foam in the reservoir. I am not using a vacuum system, instead trying the lock-to-lock, top-off-the-reservoir method. But I've probably gone lock to lock now about 120-150 times. I'm still getting the fluid level to drop a bit in the reservoir so it feels like I'm making progress. Yet, every time I start it, the pump soon starts making a sort of sizzling sound and the reservoir then fills up with foam.
I'm about to tear it apart and start again, thinking I've got air getting into the system at some point. But I'm nearly certain I did everything right and that it's all buttoned up tight. But man, I'm pushing wit's end here. I don't want to be on the verge of being finished and then tear into it again and have to start all over. I also don't want to be constantly bleeding air that I'm introducing into the system every time I start it up.
Going on a week now and I'm searching high and low for any input/guidance/advice. I did this myself to save money and out of principle I'm going to finish it. (By gawd.)
AM I still burping air from the swap? Or do I have a leak? Thanks a lot.
