Default How to Change your Thermostat [Video]

Hey guys,

So I made a video to show people how to change the thermostat on our PT Cruisers.
How to Change a Thermostat in a PT Cruiser - YouTube

Let me know what you think.

Very good. For future reference, the bolts for the thermostat housing take 110 in-lbs if your using a torque wrench.

Nice video....
A couple points to note:

Metric wrenches would be the proper tools for a PT Cruiser. Although you can if carefully used in a pinch the ones mentioned in the video.

There is a drain plug at the lower tank of most all radiators that can be used to drain just enough coolant to do this procedure. You will get less coolant over your working area which will ease in looking for leaks when the job is completed.

Most MOPAR thermostats come with a "giggle valve" in the mounting plate. As indicated by the factory service manual. It is to allow air to escape from the top of the cooling system, aiding filling, and avoiding steam pockets. A good idea if the replacement thermostat used does not have one drill a 1/16" hole near the outer diameter of the thermostat which will work with the same effect.

The radiator cap should be replaced at the time of changing a thermostat.


A short test drive should be done to allow the complete power plant to heat to operating temperature and the thermostat to cycle a couple of times.
Then when engine temperature allow the checking of coolant levels and the bleeding of the system.


The 45209 Stant used in the video is a 195 degree thermostat which is an excellent quality replacement thermostat.

Two things I'd add to the video are , you want to lay a straight edge across the bottom of the plastic thermostat housing to check that the mating surface is flat. I've found that the brass inserts are a bit higher than the middle of the housing. I use a fine file or a piece of glass with fine sand paper as a good surface to take off the high area.
When installing the bolts, lay a piece of paper towel or thin cloth across the socket opening, then push the bolt head into the socket making it a snug fit. This will hold the bolt until you get it started and you will not have to try to reach down and hold the bolt in the socket with your fingers.

Changing my thermostat to a 180 because I find the fan is always coming on even in the Winter.
Also changing over to to G-06 HOAT antifreeze.
