Has anyone noticed on the maverick x3 the exhaust half of there turbo glowing red hot in the dark? I’m just wondering if this is normal or do I have an issue I need to fix. sometimes when I stop I hear a squeak for a few squeaks, not sure if it’s the belt or the turbo bearing or something, this just started. If it’s the turbo squeaking maybe that’s why it’s glowing hot.

It's normal for the turbo to get red hot. What is bad is riding hard, then shutting the engine off while the turbo is still red hot.
What happens when you immediately shut the engine off, you stop all oil flow to the turbo. Over time, the oil cooks and burns the oil left in the turbo. As time passes all of that oil will coke up and eventually restrict or block off oil to the turbo bearing. The end result will ruin your turbo, blow out the seals, blow oil and smoke all over and possibly start a fire.
What I do and always have done is once we get to a place to stop no matter how hard we were driving, I always let the turbo "cool down" and let the oil and temp stabilize before shutting the engine off. The majority of people do not do this, and it will eventually catch up with them over time.

Listen to desertguy's advice. Turbocharged airplanes, turbo backhoes, turbo diesel trucks, and turbo street cars -- they all need a cool-down period to keep the oil from coking. Many have recommended cool-down times of 2-3 minutes. On my hauler I idle and watch the oil temp drop to a safe temp.

Well this is information that should be given when purchasing any with a turbo. My x3 and my 2019 truck are my first turbos, I never new this. I’m sure I’ve shut the x3 down hot. I took the panel off last night to look at the blow off valve, it was bowing off to mush and I wanted to tighten it but things where to hot (I loosened it recently trying to figure out where it should be adjusted). Anyway that’s when I saw the glowing red hot turbo, it seemed like it stayed red hot the rest of the 20 minutes I was out, novas bright as it was but a steady low glow easy to see because it was night time. I was testing it after throwing some codes last trip out, and I was romping on it allot. I ran the winch to hot and it kept shutting off the engine and threw 5 codes, turbo low boost and low voltage seemed to be the topic. Thanks for the information, I’ll try to let it cool down now.

Your owners manual mentions turbo cool down.

Sounds like you should read all your manuals.

Tell me more about these squeaks after you shut it down.
not when I shut it down, when I come to a stop, not all the time but it did it allot last night. Stop and it idles down and something starts squeaking, if I give it a little gas it stops, then idle and it’s back. But it wasn’t doing it every time. I couldn’t tell if it’s the belt of the turbo area. If you put it I. Park it stops. It’s probably the belt. I’m going to pull the clutch cover today and look around.

Maybe there’s a squeaky mouse making the noise:)

turbos are running at over 1000 degrees .....normal . When you turn the key on, prior to starting you’ll hear the oil pump pushing oil into the turbo . Start you engine when the sound stops .

Really....Your saying the Oil Pump is electric ? I believe you are hearing the Fuel pump spooling up to presure.......

yes I definitely hear the fuel pump pressurizing. I read and wrote it wrong in my post ......from the manual it says to wait 10 seconds on a turbo model to allow oil to flow into the turbo.

I know that I read somewhere that you’re supposed to turn on the key and wait until the needles on the speed and rpm make the full sweeps and stop before starting the turbo models and it had to do with the turbo and oil flow
