What temp does your 4.0 run at?

186 off the ultra gauge +/- 3*

 

Pretty much.

 

181 - 185 ish haven't had data from the summer yet.

According to my raspberry pi project!

 

Remind me never to stand close to you. You my friend have shit luck!

 

"Buy a Toyota", they said........"it'll last your entire college career and more", they said.

 

Go get a Chevy lol

 

184-193

 

Lol ewwww, no. lol. Anything but that.

 

On my 08 v6, this is basically the temperatures I see. I think I've seen 195° at most, so I can't say what temperature would be in the red. 100° is where the gauge starts to register.

 

Yeah, after this experience, I no longer trust the gauge on the cluster....for me, the needle doesn't move from 180-210.....too great of a range with no movement for me. When it gets above 210, it moves quickly.

 

UG puts me at 186* running flat hwy w/ no load & 195* up hill hauling 1000+ lbs.
Not too sure how accurate UG number are tho.

 

My ultra gauge always says 181-186°F. We’ll see what happens this summer.

 

My Tacoma hangs out around 184° it was overheating for a short period after an offroading adventure when the original radiator got plugged with mud, first thing you should check if you're overheating! I figured I was due for a new rad anyway and replaced it, no problems after. I almost never see it get to the 190°s, maybe in crazy Florida heat and humidity if I get stuck in traffic.

Even before I replaced the radiator it still hung out near 184°. I may have the 170° thermostat, or possibly my other mods help a bit.

 

My temps have been varying with Florida’s wierd weather. Believe 80 degrees air temp and A/c full blast at 70mph I’m around 188.6. Above 85 degrees same everything else, I’m around 190.4-192.2 at or below 75mph. If I hit a hill it’ll peak to about 194-195.8 and hen drop right back down to about 190.4-192.2. Last week though we have an hot ass day and temps were in the 93-95 area and felt like 101! I was steady at 194.0 degrees and 195.8 on a hill or working the truck but it would drop down almost immediately or within a. Few seconds. Hope this helps anyone out. I’m pretty anal about my engine temps after a off-roading event where mud clogged my radiator :/

 

Alright guys it’s starting to warm up out there, what you guys getting for temps? Tranny and coolant?

 

My scan gauge is avg 185-190 which is nominal

 

City driving? What’s your ambient air temp? It’s dipping into the 90’s here in Miami with almost 100% humidity and I’m around 192.2-195.8

 

192.2 pretty consistently

 

City and a little highway. I’m in Houston Texas and it’s about 91* today. But it’s stayed at that temp consistently. Only time I’ve ever seen it be 192-193 is when I’m on a long drive out of town in the summer heat

* Also mid grade fuel, dcsb prerunner, on 315/75r16

 

My average houston temperature for my 2015 DC TRD-OR 4X4 Auto with 265/75/16s has been 186 (scanguage 2). goes up to about 196 when I’ve got my boot in it. I also usually run 87 octane
