Probably the back of the head. Use an LED flashlight and a mirror. Shine the light on the mirror and direct it on the back of the head and try looking in the mirror at the same time. A dental mirror is too small. The one I have is 1 x 2" on a telescoping rod with a flex head. I got it in the bargain bin at Harbor Freight.

Freeze plug size?

Just wondering if anyone can tell me what size freeze plug I need to replace the one on the back of the head? 2001 XJ classic.

Not sure of actual diameter size but can order them specific for engine. These are brass for the 4.0 https://www.summitracing.com/parts/r...jeep/year/2000
I can measure one if necessary.
