Parts book shows no bolts.

 

Thanks Ron. Looks like I'll have to call the dealer for this one. I'll order the other parts online for cheapest repair price. Appreciate your help as always.

 

I just pulled up to see where yall's was on a 3.8L. Looks like that thing sits vertical in an easily accessible location; much more convenient than on the 3.6L. That being the case, I'd definitely go with the "if it ain't broke don't fix it" cuz it looks like a 5 min job if it ever does start throwing code on you.

 

I def want to at least order the correct parts for the lowest price and if/when it does happen have them ready to go. I'm due for a coolant flush soon also, so if that gets done, I might as well change these parts out at the same time.

 

Why. If your sensor works then it has 100% chance of working. If you buy a brand new one you aren't getting a 100% chance. And unlike an internal part I may change for preventative maintenance...the sensor is right or in the open and easy to change. Takes 10 minutes. The old one you have will likely be plastic from the factory. The new ones from Mopar will be brass. Its easiest to take off the throttle body 4 bolts and clean it while it's off.

I own a shop alus I own an 08 Rubicon, and have changed many. People seem to want to change the sensor when the thermostat fails. To me it's foolish to take out a sensor that's reading correctly. At least the 3.8 is easier than the 3.6 sensor down on the block.

 

I was planning on leaving the sensor alone but changing the thermostat and housing. Is this what you are referencing?

 

Yeah. I was talking about the sensor.

If just changing the thermostat or housing i pull the throttle body and clean it up too. One could change the thermostat without pulling the throttle body maybe. But it's probably just as fast to pull it for better access. Plus you can clean up the butterfly with some throttle body cleaner

 

I clean the TB often. It makes a huge difference. I'll report back.
