So I was working on a 2006 Dodge Caravan and Revane said it would fit my car. When I removed the case I carefully checked the fit and while that might have worked, it didn't have adjustment lugs like the stock thermostat or the Car Quest thermostat I put in instead. There were two very obvious alignment nibs on the case. This thermostat just seemed to want to float in the recessed rim of the case. When I put the case on for the first time, hand tightened the screws and looked at the hole in the tube, it turned out that the thermostat was not seated properly in the recess. I took it off and just went to a parts store and got a Car Quest thermostat cap that fit perfectly (it had alignment cutouts. I don't know if it's really the wrong thermostat or just a bad design but I didn't) to use I wasn't sure if it would work properly.
