freeze/expansion plug

Postby jdaivs1 » Mon Mar 21, 2022 4:23 pm

Anyone have a parts number for the plugs that go into the head near the injectors? There is five of them if I am seeing correctly. Most places I went to don't even have a listing for a 5.9 Cummins head freeze plug. The one that did had one that was too big and one that was to small. I think one was approx. .880 and the other was .703. I need something closer to .810. I guess I just need to order them from Cummins.

Pretty sure they are 52mm, that's why they are hard to find locally.

Just enough power to break everything behind the crankshaft.
