How To 180 Degree Thermostat (Write Up w/ Pics)
Parts you will need:
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)
Comparison of the Old and New
Same Motorad as the Jet, Just Much Cheaper:
Tools you will need:
1 ratchet (i used a flexible)
1 6" wobble extension
Gloves if wanted
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:
Comparison of the Old And New Again:
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.
Took me 15 min. to change out the thermostat and I didn't time it after that to warm it up and make sure everything was good. Very easy mod!
A big thanks to this mod goes to OLDHOTROD who provided the part numbers needed to do this write up!:smileup:
Well done. The 180 stat is a nice little mod.
Thanks I got this, b pillar tape removed, lower grill removed, and did some looking around at that y pipe.
Nice work but why did you decide to do it? Years ago it was fairly common; some people changed them back and forth seasonally but I thought it was a bad idea now with computerized engine management.
^Oh and the main reason manufacturers run ~200 deg thermostats is because more heat helps with emissions.
Everything he said, I live in Alabama and it does not get very cold. I have done a lot of research on this and couldn't stomach paying 60 for a thermostat so when I was given a part number I bit the bullet and did this write up while in the process.
^ good write up :smileup:
thanks, I try to do write up or give tips on all mods I do
So the Duralast is in fact the exact same Motorad that Jet charges $35 for?
