About to change my freeze/core plugs as part of an overhaul. Had a leaking rear one.
My question, has anyone changed those little threaded core plugs before? Along with their freeze plugs? Should they be replaced along with all freeze plugs? I’m thinking not necessary but I should mention my cooling system was very neglected by PO, I’ve since changed everything minus the heater core.
Also Jeep has been In Texas it’s whole life so never had salty roads to worry about. Just some previous idiots neglect.
Thanks y’all!
(Also I assume the rear one has oil behind it? So mostly talking about the ones on side of the block however I am also gonna do my RMS so while engine has no oil may change cam plug)
