How To 180 Degree Thermostat 2010 Dodge RAM 1500(Write Up w/ Pics)

part #4128 (alternate part #15128) 180 degree thermostat from autozone $14.99

1 gallon of coolant coolant $10.99

=$25.98 plus tax.

I had a 20% percent discount and ended up spending $20.78 plus tax!:smileup:

Depending on how many miles are on your truck, you may need to get a new gasket for the thermostat, the only problem is they do not sell just the gasket at any parts house i have check so u might have to buy the factory gasket and rob the gasket off of it. (part #41603 if you need it)

Procedure:
1. Let the engine be cool! Do NOT rush and burn yourself!
2. Loosen the clips that hold the upper radiator hose to the fan housing and loosely pry up, this will give you more room to work with once it's loose:

3.Locate the thermostat

4. Remove the two 13mm bolts:

5. Move the upper radiator house to the side (keep clear of the belt and anything else as not to get coolant on it)

6. Pull out the old 203 degree Thermostat:

7. Remove the gasket off the old thermostat and place on the 180 degree thermostat

8. Place new thermostat in housing, Note: it is a little tedious to get the gasket to completely go down but just go slow and work it around in small increments.

9. Place the 2 13mm bolts back in, fill up with coolant and your job is done.
