2012 Jeep Wrangler temperature

Asked by Spiryd779 Jul 27, 2020 at 01:12 PM about the 2012 Jeep Wrangler Sahara 4WD

Question type: Maintenance & Repair

Hello all.
I was on a road trip for work from Delaware to
Texas. Jeep was running fine until I hit the
mountains of West Virginia. Under load my
temp gauge starts to climb but when I come
back down into about 2000 rpm the temp
gauge comes back down. Stopped in
Kentucky replaced the thermostat and had the
radiator flushed. Continued my drive and
same issue was happening. Got to Texas and
replaced my water pump. Issue is still going
on I keep pulling over and looking for leaks
and their is none. I also keep letting the
engine cool and checking the coolant level
and it is still full. Any ideas on what my issue
could be. I have one of those no spill funnels
so I can try to burp my system again. The first
time I did I feel like I let it idle for to long
because once I turned the car off it started to
boil over out of the funnel and I started the
process again for a shorter period of time. Any
ideas would help. Thank u

Are you pulling a heavy load? Maybe a camper or a trailer? If so the vehicle may be overloaded and the cooling system is working beyond it's capacity. It is also helpful to reduce your speed when climbing steep grades. It's also not uncommon for the temperature gauge to climb past the 220°F mark in the summertime when pulling a load up a steep grade. If you see the gauge approaching the 240°F mark under these conditions you have something going on. Hope that helps! Jim

Jim. I wasn’t pulling any load. I do have a honey comb grill and a winch in the front bumper. U think because I came from Delaware and to a lot hotter environment it’s normal? Could I throw in a racing thermostat that opens at 185 instead of the 205?

The grille and winch could definitely be a factor. With a reduced airflow through the grille and, of course, through the radiator the engine will heat up in a hotter environment. Especially under the load of going up hills. Normal thermostat temperature is 195°F for your Jeep. Hope that helps! Jim
