Where is the thermostat located on this truck? Any special points to change? Thanks

 

the thermostat is in the lower radiator hose. i would recommend replacing with a 180 degree thermostat. I did in mine when i had it and it made a difference. There is one available from NAPA. i don't have the number of the thermostat with me, but if you look in the FAQ thread, there is a listing in there. it's the same for the 3.7 as for the 4.7

 

I would hesitate to just toss a 180* thermostat in there. In some cases it's beneficial and in some cases it causes problems.

If you are bone stock you don't need a richer air/fuel ratio. Also if you live in a cool climate and don't do a lot of highway driving you could create oil sludge issues with a cooler thermostat.

Now if you have modified the vehicle, resulting in advanced timing and need to pour more fuel in the mix, then a cooler thermostat might just be the ticket...

 

Thanks

 

Would it be beneficial to get a new thermostat housing gasket?

 

on my 2011, the gasket is built into the housing by an o-ring. it never leaked even with multiple removal and installations.

Not sure if your 04 is built the same way, even though it's the same engine.

 

According to rock auto the 2011 takes the same gasket, FELPRO #35692

Was only asking cause im about to replace both hoses and thermostat. For $1.70 im just gonna do it. Thanks!

 

Yeah, I'd replace the gasket any time I replace a thermostat...
