2002 Jeep Grand Cherokee Overland coolant loss

Old fart with a wrench
The word I got was they started using the "TUPY" head during the 2002 production run, so I imagine they used up the existing stock of heads.
If you shine a strong flashlight down the oil filler cap hole, you should see a "TUPY" molded into the metal if you have one.

Question about the heads...
I have a 2002 Grand cherokee laredo. Mines had the same coolant loss with no appearent leaks. Mechanic said replace radiator cap. Did that now still same thing. Did they roll over using the 0331 heads in the 2002's to get rid of them? Or is there a certain date of manufacturer they stopped using them?

Once the pressure test is done you can change your oil and use a UV light everywhere.
