So I recently purchased a 2014 Silverado LTZ crew cab. This one has the 5.3 L 6-speed engine. When I am driving the temperature gauge seems to literally be right at that center 210 degree mark. which to me seems really high compared to the 2005 GMC Sierra that I used to own, which never went above the mark below that one. What does everyone else see for that temperature piece because to me I feel like that's not normal..

 

In an attempt to help I did replace the air filter with a K&N, but that didn't do anything.

Oil in the filter will clog the mass air flow sensor

Oil in the air filter? How would that get in there and how would I get rid of that? I have 800 miles before whatever was on my 70k mile warranty and want to try and verify it it's something I need to get serviced or if it's a simple thing they wouldn't cover anyway.. but more info would be helpful.

1.) Over oiling and K&N causes problems. Using it as intended in fine. 

 

2.) Factory thermostat is 207F with a +/- of 3 F. They run them hotter and hotter. 

 

I replaced mine with a Jet 170 F unit and LOVE IT. So does my oil temperature. :seeya:

So I thought I was clear when I stated I added the K&N to help with the problem. Meaning I added the K&N after the fact. So the K&N cannot be the cause of the problem because the problem existed before that was even in the vehicle..

 

Forgive me if I came across as short. But I tried to be straight with that fact. As I deal daily with people blaming aftermarket parts for causing issues.

 

Grumpy bear. Thank you for your second point. That is the kind if information I was looking for to see if it was normal or abnormal for the temp to be that high.

My 07 ran there and so does my 15, it's normal.

You want hot, my 06 GTO fans come on at 226 and go off at 215.

I have a ScanGuage II in my Sierra. I can monitor engine and oil temp. I found the engine temp gauge is kind of a "dummy gauge". By that I mean it's not really that accurate and just floats around 210F. In the cold winter months, normal highway cruising (not towing) I see between 192-196F. Summer time closer to 202-206F. Summer time towing in 5th gear 210-215F. In all these situations, the engine temp gauge needle is pretty much in the exact same spot. As grumpy bear mentioned 207F is thermostat temp and normal.

You were and I was being supportive. I assumed you had it installed correctly oiled. 

Your welcome on both points.

Yes it is. There is also an oil temperature PID for your Scan Gauge II. Oil temperature is the reason I installed the lower water temperature thermostat. The oil cooler is 'in' the radiator tank on 15 and up K2's. Was an option in 2014.

 

I never want to see my oil temperature above 212F/100C. On a hot summer day it was over 245F. Runs right about 200 F now. Little cooler in the winter like 190F Plenty warm.  Anyway....:seeya:

Wow 245 is a lot warmer than I have ever seen my oil temps go. Not towing, I usually see oil at or 5F cooler then engine temp. Towing my 3000 lb boat on a 90F day I may see 215F.

That's interesting. Mine is normally, now, 20 F more that water temperature. I tow nothing and drive pretty slow I'm told. :rolleyes:

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.
