Anyone else have a 14 5.3 that constantly whines? Almost sounds like an alternator going bad or something but ive used a rubber tube trying to hear what the sound is coming from and there is no one place. You can hear it pretty well in the video and the motor was up to temp when it was recorded. the phone is sitting on the plastic radiator cover with the hood open.

I've noticed this same noise since mine was new. Notice it more before the engine warms up. Dealer service says it's normal, although the tech was unable to say just what it was.

They all sound like that I don't know if mine has gone away or I just don't hear it anymore but it was very noticeable when I first got the truck

10 4 I figured that would be the general consensus is it was normal truck seems to run very good so didnt think it was to big a problem. Guess ill have to put a blower on it and maybe that whine will drown out this whine!!

Same noise here and my dealer claims it to be the fuel pump. Still it sounds like a 1986 Ford Taurus with a bad steering pump, annoying as hell imo.

Have you checked the PST fluid while it's running to see if it's foamy? Might be sucking air.

I guess mine has a little whine. I don't have any issues and the engine runs strong so I am not to worried about it. Just turned over 70,000 miles yesterday.

(Normal) yes the DI engines make some unfamiliar noises. Once they get the electric propulsion perfected we will have no noise and we will really miss the Real motor noises. Make sure and save that video so the grandkids know what a real truck sounds like.

You should hear the GM 3.6 they whine way louder then the 5.3.

 

The DI engine in my truck makes less noises then my 2013 then the DI 3.6 the Traverse had.

To me it sounds like the new oil pump they are using. But as long as everyone else does it I'm ok I reckon. Now back to figuring out how to get rid of this vacuum pump.

My 2014 makes this same whine noise. I bought the truck used and did not really notice the whine until i began driving it regularly. It is constant at low speeds cold or hot. I initially thought it might be the transmission but after this video it seems like it could be the engine. I feared it was a bad alternator or steering pump etc... Engine is running strong. I am about to change the oil so we'll see if that makes a difference. Anyone find out where the noise is actually coming from?

      287,500 Mile Service   8/13/2026   Reset Fuel Trims   Since the work done in the previous post there was a good improvement in response in all areas except right after a fill up where the LTFT would go -20%+ for about four miles while the STFT was near neutral. Before the work they both went very negative for a few miles after a fill up but act normal thereafter.    We did a systems check of the vapor recovery system for functionality and ability to hold a vacuum. That checked out fine. But this doesn't mean the charcoal canister is dead in the water. Testing that is next up. For now the reset of the fuel trims.    I intentionally shorted the fill exactly two gallons to eliminate any chance of filling the canister. On start up the trims were behaving normally until I got up and rolling where the LTFT went -10 / -11%% but the short was + 2 to 0%. Within a mile the the STFT offset the LTFT and by 2 miles they were neutral. HUGE improvement but still not hunky-dory.    I'll watch them for a few days. Perhaps another tank where I will fill completely to 'first click' and compare. Meanwhile on the hunt for a new canister and I'll toss another purge value at it for good measure. Pending the outcome of the canister test that is. Progress of any kind is welcome.    Fuel economy improvement with bringing hole #3 back to the living was a noticeable bump to the positive. Even on the few miles I drove after the refill I already see another bump up by the trims reset.     She's purring like a kitten with a warm bowl of milk.    BTW, adding 50 rpm to the idle took the majority of the negative timing out on cold start up and leaned the cold idle. No longer burbles in the cat. What a dumb way to heat a cat.

      Yeah, shame I can’t really get that filter easily anymore. Running a PureOne. Your fave!    TAN would be neat to see. Confirmation I ran it too long probably. 🤣

      Roll up bed cover experiences

      By superdave160 · Posted

      My son and I both bought new trucks in 2017. Both of us immediately put Truck Covers USA American Roll Covers on our trucks. My son still has his truck and it never sees the inside of a garage. We live in Alabama, so not much snow. My truck was my daily driver and was in the garage when I wasn't driving it or at work. No issues with either cover even after almost 9 years. About a year ago I sold my truck to my brother and bought a 2025 Silverado 2500. The second thing that I put on that truck was a new Truck Covers USA cover. They are very well made and have a very positive locking system. I looked at a Retrax and my concern was the way that the cover locked to the rail. BTW, the first thing I put on the new truck was step bars. Those new trucks are high!

      The Allison 10 speed torque converter doesn't "lock up" like the previous transmissions. It has 4 operational modes; open, slip, transition from open to slip; transition from slip to open. I have an Edge CTS3 monitor and I monitor transmission torque converter slip. Step on the gas and you get a little slip. Take your foot off the gas and you get a little negative slip. I have not found a way to display the torque converter mode beyond that. My Edge CTS3 also displays something that our trucks should already display, the current gear. I also monitor throttle body position and engine load. If I see the engine load getting too high, I'll manually drop a gear.

      Nice result. Your filter is working well  I'd have like to have seen the acid number for this sample. Curious type that I am.
