Default thermostat change

Anyone have a how to on the t-stat change? Looking to do mine because I think my coolant is not coming to temp. I drive 30k to work every day and the heater just blows warm when I am there and should be hot right? The guage only shows at a quater for heat also.

I've changed mine. It's easier than it looks. You do have to remove the drivers side tire and go through the wheel well. The gasket is built into the t-stat which makes it easy. I used a 1/4" drive ratchet and socket and a couple long extensions. I also used a universal. There is a trick to it, I had to put tape on the universal to make it stiff because you have to go in at an angle to access the top bolt. The stock one didn't have any rtv on it so I didn't use any, just took the old one off and put the new one on.

Don't forget to drain the coolant first before all that. :D

How much coolant is going to come out of it? Is there a way where I can save it and put it back in or should I just get all new stuff?

new fresh coolant is always best as you can contaminate it draining it. Unless you are real careful about it.

I would re-use the existing coolant. Use a clean drain pan (new if possible). You may loose a little bit in the recovery process, so top off with pre-mixed Decool after running the system for a while (letting the air burp out).

Total Cooling System Capacity:

* 10.6 quarts
* 10.0 L
