BE VERY CAREFUL with the thermostat housing bolts...they like to break off in the intake...and dont forget to burp the cooling system really good when you're done!

lolololol made me laugh

Sure...it's really easy if ya got a set of ramps or somewhere where you can park the nose of the truck up on an incline. the idea is to get the radiator sitting higher than the engine and heater core.

Get the truck up on an incline, let it cool down...open the radiator cap and pull it off. Turn the truck on and let the tstat cycle open and closed a couple times...any air in the system will find its way out the water neck on the radiator...you might have to add a little more coolant after it burps as the level might go down.

Here's a guide for the 4th gens, but step 6 is how to burp it, and it's pretty much the same thing.

EDIT: I like SmokedRam's better though!

thanks guys, Ill be sure to do that after I install it.

damn I have alot on the checklist to do...

thermostate
bleed brakes
fix o2 sensor issues
replace grommets that dont fit installed by a moron apparently

-_- more time in the day is required

 

[wermbang]

when I did my thermostat it wasnt that bad

 

[the codes]

so you didn't have to remove to much?

I'd say it's closer to 180...160 being the mark after 130.

Probably about right if you're running a 180 stat. Does the temp go up slightly in stop and go driving in these gdss awful temps we're having? I wish my ram ran that cool Got up to the "2" in 210 today with a 180 stat. But it was 105 degrees at 5 pm.

Overheating from an open t-stat usually occurs at higher steady speed driving because the coolant doesn't have time to stay in the radiator long enough to cool.

Mileage wise you probably won't notice much of a change with a hotter stat. What you might notice with the SCT you run is a bit more pinging at WOT even with a mild tune. Running engines to the point of meltdown is wonderful for emissions burn off.

Guys who move thier IATs into CAI tubes or buy those stupid ebay "resistor boxes" will likely kill mileage quicker.

 

[the codes]

no it doesnt fluctuate to much, it moved a little closer to 210 after a while
driving but not a ton. maybe it runs cooler b/c of the Hughes FI gap?? and my stat isn't failing..?

I'd say your stat is fine.

Now if it oveheats while driving for a long period at a steady speed, or "spikes" while warming up and then goes back to normal, that might be an issue.

well I drove it during winter/spring and the only time it would get past 130-140 was on my hour long trip to where I was going to school. idk if that's bad or good...

How is your gas mileage? Is it terrible? Because that seems low for operating temp, that's my only concern.

 

[the codes]

when it was 130-140ish (guesstimating) during the winter/spring I was getting 14.5 mpg with 85% highway miles. that's pretty good as far as I know for 2nd gens. about 10-12 now with mostly city.

[Trupiano]

Well that's not too bad at all.

 

[Okiespaniel]

130 ish is bit low. I would think that would set off a CEL.

You don't have one of those "fail safe" stats do you?

 

[the codes]

its the same one that came with the truck off the dealership lot.

and the only CEL codes I have are all stupid o2 sensor codes.

 

[Trupiano]

Has it ran this low the entire time? Like from the time you bought it?

Maybe the problem is linked. Maybe your truck is sensing the colder coolant and engine temp from the open thermostat and adding fuel to compensate, resulting in a carbon buildup on your O2 sensors and causing them to fail... Hmmmm.

Someone else mentioned this...

X2...the PCM is just gonna adjust your air/fuel ratio and make it could start to burn rich...enough of burning rich = valve problems, catalytic converter problems...etc over time. That's only if you're running too cool for the engine to go into open loop.

Just spitballin here...
