Well, one time it did overheat but I had just put coolant in it so I opened the radiator and let it run to bubble out the air and then I just put more in it and it fixed it.

Have you looked recently? Disappearing coolant and low oil pressure is very bad.

Yesterday was the first time I drove it since that incident. Thing is though, the radiator cap is on a 90 degree angle so I can't look in there to see

Check the reservoir on the passenger side of the engine bay. Square yellow cap that flips up, next to the fuse box.

Read this page for more information: https://www.cherokeeforum.com/f2/00-01-xj-cracked-cylinder-head-overview-118922/

Check your oil and verify the pressure with a mechanical gauge.

Very good, you learned basic high school fluid dynamics. Do you want a gold star?

When the oil pump is pushed to create more flow, there is greater resistance against that flow because bearings and clearances do not get larger. The relationship is not linear. As a result, the pressure increases.

CCKen has some great info on this over on NAXJA: http://www.naxja.org/forum/showpost.php?p=245993828

Pair that up with cruiser54's Mostly Renix Tips

Your location says PA. So probably not lol.

Air hammer definitely helps. I used a 10- or 20-ton press. The bushings are contained in metal sleeves, which rust to the metal eyes lol.

A press is probably the best option lol. With heat and pb blaster, some swear words and blood

If my radiator cap has an elbow, and the reservoir remains full, how can I be sure it's loosing coolant other then the obvious; it overheating?
