Getting kinda hot....

**Boostf3d_TSi** · 05-26-2016

So driving home from picking up my car with my truck and trailer, the truck started to get fairly hot. Not necessarily while pulling but when I got stuck sitting in traffic. It got into the 230s before I could pull off and turn it off. Kinda seemed like tstat not opening correctly or something. I know a motor driven fan isn't going to push a ton of air at 600rpm but still. When I got going again on the interstate it went down to and stayed between 197 and 204. But anything slower than 50mph or so such as in town it stayed 201 to 206. Which seems a lil high to me while idling and slower speeds. Coolant level looks fine. Temp outside is in the 80s, so it's not like it's Arizona weather.

What can I do? I don't wanna have to worry about getting caught in traffic and it overheating again.

Makes sure first that there is no blockage/dirt/bugs in the fins of all the coolers up front. Check the fan clutch to make sure it isn't going bad. I'd start with those.

FYI

You have 2 TPS sensors. One failsafes the other. They have some control of the fan clutch as well. But if one isn't working, the fan suffers. You can keep changing the clutch, but it won't work without the TPS. Sometimes there is a soft code and sometimes there isn't. If you can get it on a scanner, you may find some telltale indications.

I would contact @Geno's Garage and replace the TPS assembly.

We've solved your problem countless times by replacing that. This is a little known fact. I found it buried in the FSM a few years ago when I had your problem.

The Edge cts shows a code p0480 I think, "cooling fan 1 control circuit open".

What do yall think of that?

I know it's not the issue but I think I'm going to change the tstat and get a coolant flush to start with. What temp tstat is recommended, 190?

But then what do yall suggest?

190

0480 can be a bad fan clutch or disconnected. But if all that is in tact, then it's the TPS as I told you about
