Hey everyone!
Just joined, so I am introducing myself, names Trevor. I've got a 99 LC 100, gas 4.7, Emu on 35s. Fully locked. It is old, but it doesn't make me cry about desert pinstriping. Had it for 5 or 6 years now, always on here looking for data, but was never able to join for some reason. I tried again based on my recent experience redoing the starter motor, which was a pain, that second bolt in the back on the driver's side was killer. Anyway, I was putting it back together and leaned on the coolant pipe running through the valley, it leaked some coolant, I inspected the oring and it had a flat outer edge, time to replace. I spent the next 3 weeks trying to find the right oring. Dealer got it wrong, Amazon got it wrong. Eventually I ordered a whole bag of 50 from McMaster Carr, now I have spares if anyone needs one
. That said, in all of my research finding the correct oring was a pain, I wanted to share the results of my research. For the 1999 4.7 at least, it is a 19mm ID x 2.5 mm cs x 24mm OD, make sure that you get it in EPDM, silicon and NBR (nitrile) don't play nice with coolant. So far so good. I'll keep you posted if it fails.
Anyway, thanks for having me.
