[QUOTE="Anybodyhome, post: 447145, member: 19161"] 1 of 2 probable culprits: Temp sensor and thermostat. 1. T-stat. There are a bunch of cheaper versions out there in the $25-40 range, but the MOPAR replacement, with housing, is around $53. 2. Temp sensor: Again, cheaper versions in the $16-24 range, but the MOPAR replacement will run you about $38. I have to believe it's one of these unless the fan somehow got screwed up when you replaced it. Check the fuses and wiring on the new fan. Has it ever run at any speed except high? If it runs at both low & hi speeds, the fan is not the issue. And one more thing- if the t-stat was stuck in the open position, you'd see the temp gauge all over the map, from low to high, with the higher temps occurring when the Jeep is standing still.
