Effect of start/stop on turbo?

to ignore someone, click on their profile pic, you will see in the window follow/ignore.

it works. I havent seen a post from RedLandRanger all afternoon

Thank you.

If only the engineers at Ford could have thought of this.

Two answers: first, the cooling system is sized for towing 7000+ pounds up a mountain in 100 degree heat--it isn't stressed driving around town; second, the start stop system considers factors like temperature, and also has a maximum time it will remain off.

Some people really hate stop/start, I don't really notice it except to note that it actually does improve mpgs around town.

I must say that I really hated stop/start as a concept, to the point of almost considering it a deal-breaker, before I bought the Ranger, and I resolved to turn it off every time I start the engine until I figured out the best way to eliminate it altogether (and the members of this forum have come up with some creative solutions). But, after taking delivery of the Ranger, sometimes I would start the engine and forget to turn off stop/start, and I discovered that it really was not all that bothersome to use: the motor turns off and back on quickly and quietly, and you really have to be paying attention to notice it at all. Then, when I would remember to turn it off, there I would be at an intersection, going nowhere with the motor on, thinking, this is killing my gas mileage, not to mention the environment, and for what? Live and learn....

I'm curious what will happen in the long term with the stop start system turning the engine off after coming to a stop with a hot engine?

First the turbo is liquid cooled. Second when stop and go driving the turbo doesn't get that hot its more an issue if you were accelerating and driving hard then shut the engine right off. Ford wouldn't have implemented s/s if it was harmful in any way. I'm not Ford certified but I have been a mechanic a really long time and I can't see s/s harming anything. Starters aren't damaged from multiple uses they are damaged from excessive cranking without a break. The .5 second crank it takes to start done 10-50 times in a day of driving doesn't hurt it whatsoever.

On a personal note I absolutely love s/s unless I am trying to notice it I never do. Maybe the 150 would be more noticable and bother me but with the 2.3 I can't even tell.

On another note I did notice that when I stop in my driveway sometimes it stops and then when I shift into park it starts up again. That is a bit irritating but I guess everything comes with a downfall.

Agreed mostly.

It doesn't use the starter, it uses the alternator. The MOST common failure point will be the battery lasting a few years less. I have a few batteries in the 10-12 year old range that still work perfectly, I'll be interested to see how long the Ranger battery lasts. I'm still too lazy to do the math on how much fuel I actually save vs how much battery life - X years would cost.

the ranger doesnt use the alternator does it? I know there is STARS which is a reversible alternator that restarts the engine but I didn't think ford was using this technology. I could be wrong. It would be really cool if they were but I'm pretty sure Ford's stop/start still relies on the starter.

I’ve read on here so it must be true that our highly advanced motor vehicle actually does use the alternator.

I'm still skeptical seeing a new OEM standard alternator is quite cheap. I would think such a high tech piece of equipment would cost an astronomical amount of money. From what I've heard it uses the starter which has been redesigned a bit to accommodate s/s tech including using a lower gear ratio.

Me too.
I could not find where that was mentioned so I did an online search on s/s tech and found no mention of the alternator.
Everything mentioned the starter being redesigned to handle 500k plus starts.
Cool tech indeed.

wow thats alot of starts lol

Consumers obviously know more than the engineers that designed the ranger

why of course they are

I still can't believe people think that the engineers don't think of these issues when designing new features.

1) There is an auxiliary electrical water pump that will cycle coolant after shut off if necessary.
2) The auto stop/start is run off the BISG (Belt Integrated Starter Generator) aka special alternator. These alternators can run in reverse and can provide enough torque to spin the engine under low-load conditions (i.e. when the engine is warm). By using a BISG, the starter does not have to engage every time. The other benefit of a BISG is that it does not have to wait for the engine to come to a complete stop before starting back up unlike the starter. If you let off of the brake just as the engine is about to shut down, it will spin right back up with minimal lag - it's great!

TL;DR: Auto stop/start will not harm anything y'all.

Im not positive but I dont think the ranger has the ISG. Pretty sure its just a beefed up starter. I'm not going to say for sure because I could be wrong but as a mechanic it doesn't look like a generator to me but a simple alternator. I am however, positive that s/s wont damage anything prematurely.

Phil would (probably) know...

I based my assumptions on the idea that the "starter" can engage when the engine is not even off all the way, and you don't hear any grinding. So either the starting gear is always engaged (doubt it), or the "alternator" is being used. It does have it's own belt, and there are a couple power taps that come off the battery that are enormous, and might be used to back feed whatever device that starts the car.

The alternator is 700$ or so from ford, so it seems it's not just a dumb alternator from the 90's.

Also, prolonged idling is far more destructive to an engine than starting when hot.

I'll point out that the Ranger's manual mentions not leaving the automatic transmission vehicle idling in drive for long periods of time as it's bad for the engine/transmission.

I, for one, was well used to a vehicle turning its engine off when the ECU decided it was not necessary (Even while i'm still pressing the gas! Electric-primary drive Hybrids are certainly different to drive) before i got my Ranger. An auto stop-start is nothing in annoyance compared to having my engine turn off and losing all heating in winter because i'm going downhill...

That said, I've never been a fan of options which are not saved when you turn your vehicle on and off again. I dealt with a similar annoyance with the same Hybrid Fusion mentioned earlier. During winter i had to add turning off the traction control to my startup procedure (a menu option nested like 5 deep from the main screen) otherwise it was rather difficult to to get moving at all on slippery conditions.

Yeah, I think that's my only issue with it. Sometimes it's too quick on the shutdown. So if I don't shift into Park fast enough when pulling into the driveway or a parking spot, it'll start to turn off, then crank right back up when I shift it into park half a second later. So now I try and shift into park quicker so it doesn't do that. Though I imagine now that winter is coming on fast, I doubt the s/s will be working much at all. Especially here in frigid northern Minnesota.

Ya it drives me nuts I try to tap on and off the brake and that sometimes keeps it from doing it. It seems to wait until there is a steady hold but it should wait another second or so. As for not working in the winter does it not work in the cold? I live upstate NY and it gets nasty up here in the winter.

I'm in the minority of owners who have already driven their ranger through what most would consider "Winter". I picked up on Feb 4th 2019, and I can say the S/S only worked maybe 2-3 times until temps stayed consistently above 40F. I have a long commute, with plenty of stopping, and it stays off most of the time. Not to mention it's disabled when you have the defroster on, and it's basically required if you are a living, breathing human.
