Replace both thermistats I order oem

 

Roger that, I want to get oem but don't have time. When you did it did you change your fluid or just drain the necessary amount?

 

I used the carquest brand when I did mine, mostly because advance auto also had the housing gaskets in stock too. You'll want the housing gasket, felpro 35826 and the water pipe o-ring, felpro es-72872. The water pipe oring is a two pack but you only need one. Haven't had any issues so far.

 

Thanks for the heads up So do you have to remove the whole housing to do both thermostats?

 

The thermostats each come with their own gaskets already attached and the larger (in size) 173 deg stat goes into the outlet housing. So the two stats and the two felpro gaskets I mentioned make up all the seals you'll need to do the job.

 

I just went back up and now see you list the part numbers. Thank you! I’m going to try to procure those today and knock this thing out tonight after letting the car cool for a few hours with the hood open. I’ll take some pics and try to do a mini write up in the next week or so.

 

Thanks I have not heard of 2 thermostats before and was hunting for it 😁

 

so i have a 2012 2.0 cvt2 with a manufacture date of 10/11. there seems to be different thermostats after april 2012. does anyone have any insight on this? called the stealership & they said i need 2 of the 55111017ad. seems strange to have 2 of the same temp?

tia!

 

All parts sites I've ever looked at list two different parts for the 2.0L and 2.4L (and probably the Dodge Caliber 1.8L as well since it is the same GEMA based engine). The mopar part numbers are: 55111017AD for the 203 deg. secondary stat and 55111016AE for the 173 deg. main stat. Besides being different temperatures, they are also different in size, diameter and appearance. The part number they state would not be big enough to seal the main outlet.

I should add that the only change I'm aware of where the thermostats are concerned are actually with the housing itself. They changed the heater hose sizes on 2009 and newer models, so if you have a 07-08 and are going to replace the entire housing, you need to also buy the 09 and up heater hoses.
