Hi Scotty! I have a 2016 jeep unlimited sport. I’ve been having some heating issues. It started when my engine light came on. I had it scanned and said it was a temperature issue. So we change the thermostat to a cheap O’Reilly’s thermostat and I am now waiting on a Mopar thermostat. Which should be here tomorrow.. so I decided to get an oil changed after we change the thermostat. We took my jeep to the dealership and they changed my oil and also let me know my oil engine cooler was cracked and showed us. My brother thought it was a better idea instead of the plastic oil cooler to put an aluminum one there. We put the aluminum one on and I have still had engine cooling problems. My coolant is running at 222° all the way up into 230° With the fan constantly running I sound like an airplane coming through. So I took it to the Jeep dealership again, and I had them run a diagnostic and they said everything looked good. We burped the oil coolant and it did change for a couple weeks and it’s back even worse. Not sure if the thermostat is opening. Do you have any ideas? We noticed the fan belt clicking with that be the water pump? I am clueless on this and so tired out. I wish you lived close! Please help! This is getting costly and I’m over this.
Scotty only answers questions one time and doesn't revisit them.
I’m thinking this is a good temperature but not positive
It's good. 230 is definitely on the high side. Ideally, your temps should run from 190 to 220, with 220 the upper limit. Jeeps are known to run a bit hot.
Well you have some kind of problem. Watch my video how to fix an overheating car engine Scotty. It's on YouTube. It could be the head gasket starting to blow that shows you how to test everything
Thanks Scotty! Just got my Mopar thermostat and got rid of the o’Reilly brand. My coolant is now staying between 199°-208°. Do you happen to know what the engine coolant temperature should be? I’m thinking this is a good temperature but not positive it’s better than 230°.
