Does anyone know what thermostat is stock on the 4.0 (2002) Yesterday was the first day that its been warm here all year, and it was running at about 210 ... seemed high, but like i said, it hasnt been hot out in months. [addsig]
jterp:
2002 Jeep Wrangler "TJ" 4.0 I-6 factory suggested thermostat is 195 degrees.
You can purchase these at your local parts store.
Note: The gauge reading is not always exact, so you might be running anywhere from 200 to 220. I have found it not uncommon for Jeeps to run at that temperature during warmer months without problems.
Good Luck.
