    My 2008 Commander 4.7 Flex overheated. Figured out that T hose connection going to the heater core basically was falling apart and was leaking. Replaced the old one with a new T connecter. I drove around my neighborhood trying to get it up to temp to make sure it was good to go. When the temp...

    Hey everyone, I was driving the other day and noticed the temp gauge was rather high. I stopped and checked the coolant and the reservoir was dry, so I filled it up. I didn't know burping the system was a thing, so I just kept driving. Then, yesterday I was on the freeway and all of a sudden...

    I’m new here so I really don’t know how this works. Hope I’m doing it right. My commander is overheating when at an idle both fans are working. It does have a small pinhole by the top hose on the driver side. It makes a whistling noise when the temp gets high and pressure builds up. It has small...

    We have a 2006 Commander V8 4.7 with almost 200,000 miles. The more work we have done, the more the worse it gets. The mechanics we have taken to say they can't figure it out, but I don't know if I believe that. I think they just didn't try hard because they knew we had spent most of our money...

At the same time I noticed that I did not have any hot air blowing from my vents. After I babyed her to a parts store, I checked the fluid in the reservoir. It...

    Hey guys can someone reassure me if that's what it's called? I cannot find any info on it and if anyone has had a leak coming from there before. I have a coolant leak that isn't coming from the water pump, but behind where a tube seems to go into the water pump. It also seems like someone...

    I'm going to be tackling a driver side head gasket replacement tomorrow. 2007 Overland the motor is a rebuilt 2008 Hemi with 20k. Is there anything special I should be aware of?

    I just received diagnostic code P0128 while driving home. From my search I understand it is an issue with the thermostat or coolant. Which makes sense as the following has played out in the last few days: 4 days ago I noticed my coolant level was about a half inch below the minimum line on the...
