Did you check the heater hoses? I'm having the same smell on my 21 with the 3.6. In my situation, the heater hose O-ring is not sealing at the connection. Wiggle the hose and check for coolant. I ordered new heater hose assy so once I replace it, I'm hoping the smell is gone.

Can AlfaObd or Jscan make corrections to the engine and idle hours to a 21 1500 with the 3.6 etorque ? I'm about to do the speedometer swap and not sure if those can be adjusted. I know they do the mileage.

I have a 21 1500 with the 3.6 Pentastar. I know these are prown to the coolant leak smell. I noticed that there is a leak from the heater hose connection. I traced it to the quick disconnect. Can that quick disconnect be bought separately or do I need the entire heater hose. Can't find the...

Not sure if this applies to the Hemi, but I'm having the same issue and "coolant" smell on my 21 Bighorn with the 3.6. What I found out is that this connection is bad. As soon as I wiggle it, it will leak. Going to replace it but, can't seem to find the part or part number. Can anyone help...

Problem solved... A big thanks to Jimmy07. When I reassembled the door/body harness, the connecters were not seated all the way, thus making a bad connection and throwing all the codes.

So I finished installing the passive lock system and the install was easy and functionality works. The only issue I'm running into now is the truck threw up 2 CEL, one for a P0073 code, ambient air temp, I thought I cleared it with a scanner, but it came back. The other message is the Start/Stop...

I need to replace the thermostat housing on my 2021 1500 with the 3.6 Etorque. Plenty of online videos for the 3.6, but can't find anything for the 3.6 with Etorque. Has anyone on here done it and how difficult will it be. Does the MGU need to be removed as that is the only thing that really...

Also, that sensor is buried under the intake. Is there an easy way to check the sensor, other than taking apart the intake manifold?

Richard320 and c3k both have good points. To c3's point, the AC is running when the CEL triggers. Does the fan automatically turn on full speed when the AC is turned on regardless of the temp? The dealership recently replaced the oil cooling housing under warranty, but did not tell me until the...

Looking for advice on what to troubleshoot. My 2021 1500 with the 3.6 will sometimes throw a P0128 code (low coolant temp). I run my scanner to clear it and it goes away. After doing this a few times I have noticed a few things on when that code returns and It only comes on when I am running my...

Never mind. I just noticed that the Diesel cluster tach goes to 5K RPM and my gas goes to 7K.

I'm looking into swapping out my 3.5 inch cluster to the 7 inch on my 21 DT 1500 with the 3.6 Pentastar. I've located a cluster, but it is from a 2021 with the 3.0 diesel, VIN#1C6SRFKM3MN530500, will the diesel cluster work on my gas vehicle?

Does any one know if this harness that’s sold by Mopar, is the harness that plugs into the door handles and the wire loom to the door body for adding the passive door lock?

I have a new bezel with the correct controls coming so I'm going to try that first. But now my concern is that there is still an issue with the controls even after I put in the OG radio and controls. I'm wondering if Alfaobd can fix that... I just Don't know what command that would be.

What would that setting be in Alfaobd? The strange thing is that I put the original unit back in and now I'm still having the same issue with the AC system. So the radio has to match the HVAC system the vehicle had?

I just upgraded my 21 1500 DT from 5 inch to the 8.4 screen. I purchased a used 8.4 full stack, but the unit came out of a 21 Laramie with the Auto temp AC controls and heated seats and steering wheel. My 21 1500 had the 5 inch with single zone system. I installed the unit and it was pretty much...

Interesting.... The link shows 2 options... The vLinker MC BT3.0 cannot be delivered to CA, but the VLinker MC+ BLE4.0 can be shipped to CA.... Wondering if it makes a difference?

Awesome! Thanks for the quick reply and recommendations!

Hello, all. New to Forum. I'm looking into Alphaobd to make and change options to my 2021 1500 DT crew cab. Reading through the threads,I'm a little confused on what physical hardware is needed. I know I need the app and an android device and the OBDlink MX+. Where I'm not sure, is what I need...
