Normal Engine/trans temps

Under normal driving I’ve noticed my engine running about 210, seems hot when walking by it after driving. It seems to just get this temp and stay there most the time. Just did a 100mi each way tow pulling about 8000lbs and same thing. Sitting at 210.

 

Trans was running around 180 most the time hitting 190+ on the grade.

 

I feel like the engine is running too hot but can’t find any specs for this. Should I take it in or is it something I should just mention at my next oil change.

 

I have the 5.3L (L84) with the 8 speed. Got an oil change at the dealer about a month ago.

 

Thanks.

Normal temp range for coolant is 207-220 degrees now. The cluster won't move off of 210 much but the real temp on a scan tool will climb/fall 10-15 degrees all the time.

According to what I've been reading on here that is normal given the gauge on the dash isn't super accurate. It's when the temp doesn't go down is the problem. My 1500 LD started rising above 210 on the dash a few months ago anytime I have my little 5x8 utility hooked up. Pulled it all last year with no fluctuations but now it jumps up and down like a kid with a sugar rush.

Might be time for new thermostat.

That's what I was leaning towards because if I don't have the trailer hooked up it stays right at 210 and doesn't rise at all. And it's not like I'm pulling 8k lbs or anything, the trailer and mower together is under 2k lbs. I use to pull the exact trailer and mower with my 03 frontier and never had any temperature fluctuations. And it was a v6 lol.

A new thermostat will do the same thing, if you get the stock temp thermostat anyway.

It's odd I pulled the same setup all last year and the temp never rose above 210. And it ain't even summer yet so now I'm confused because if it was normal why has it only recently started doing it?

Beats me. I put in a new thermostat before this past winter because it was sticking open, it did the same thing last year as this new one does now.

Different truck, different motor, different cooling system size, different instrument and sensor sourcing..... nothing is comparable. 

 

I haven't read anything yet that says this system isn't operating normally. A thermostat is not a 'feed back' controller with ECU driven 'logic' system that can anticipate changes in load. (Yes some vehicles are so equipped). It's a chuck of wax with a melting point that is 'reactive'. It will swing some.

 

Each piece of the system has a 'range' and no they don't all line up neatly. 

 

That said and for your piece of mind just change the thermostat.

Yea I'll be changing it this weekend if the rain holds. Still confused as to why I pulled it all last summer and put 20k miles on it and it never went above 210. The temperature here isn't even hitting the 80s yet. I guess my truck is retarded and didn't know it was pulling a trailer all last year.

Thanks all. I figure it's ok since the truck isn't complaining to me at all, but I'm just more aware of it now that I'm towing at 70-80% capacity. I've been watching more diligently, but then noticed the heat the truck is giving off when I park it too, even under normal load seems hot. Just don't recall it doing that much before. It's only been high 70s here lately, but I'll just keep my eye on it.

      I just bought one of these.   https://www.topdon.us/collections/diagnostic-tools/products/artidiag-pro   Yeah, it`s got a cable. $250/year after 2 years. Do I want more? Yep. But, I`m not working any more and can`t afford a whirlpool in my tool box.

      Why don't I have a good scanner? I've always wanted one when I've needed one.   My latest reading says I don't need to do a relearn on the ckp sensor on a 1995 with OBD 1.5. The relearn is prescribed for the later-model 1995's which shipped with actual OBD II when GM completed the transition in prep for the 1996 MY. I need to confirm that. Did you know forums are disappearing? Knuckleheads on Facebook... it's not the same. It's just not.   So, scanners. Again, shooting myself in the foot for having eBayed my Snap On MT2500 "brick" with all the adapters. Not that I couldn't buy another but those are getting quite old, and mine wasn't new enough to work on 2000's vehicles.   Damn it (as I'm scanning my email between paragraphs here). Did you know there's a 2000 Jimmy 2-door on BaT that's ending this morning? It's local. I want it. 14k miles. Absolutely beautiful.   Back to scanners. MT2500's are old. Solus, now that could be a contender. There's a ~2008 Verus with a system error that's basically new in box for cheap. Hmm...I'm not sure about a scanner that runs an archaic version of windows (95 or CE, I can't tell).   I want the ability to reset and rotate TPMS, test individual modules, bleed ABS, electronic parking brake controls for servicing brakes, relearn procedures and other bidirectional controls.   Snap On does an MT2600. It's a new model as of last year, marketed as their "entry" scanner. Entry? Only where $1900 gets you through the doorway plus, I'm guessing, $1000/year if you wish to keep it current. So goes scan tools actually designed for production environments. Want decent products with excellent support, you pay for it.   Everyone is raving about Autels and TopDons and Foxconns and all these newer brands that are selling the $500 "prosumer" scanners for backyard hacks like me. They're tempting...honestly. Updates are cheaper, base prices are remarkably cheaper... And you get to deal with bugs and translation whoopsies and, well, just don't use it on anything expensive, OK? Having a dealer replace an ECU because it needs to be re-imaged after an adventure in scanning is no joke. But I think most people are getting by OK with these units.   eBay on a scratch-and-sniff pro-model oldie, a shiny new TopDon, or???   God dang it, I can't stop looking at this Jimmy. I'm ready! I'll Bring The TRailer! It's beautiful.

      What have you done to your K2 today?

      I removed the OE running boards.  It looked so much better.  I wish I took them off a long time ago.     I had to put something back on for my wife.  I wanted Westin Sure Grip Running Boards but they are very pricey, like $600 plus.  I was going to go with the Ionic 41's like I had on the 2019 Silverado but went with Westin Outlaw Drop Steps instead, about $200 cheaper.  They are sturdy and functional but not super crazy about the look, but it works.
