2024 Tacoma Owner's Manual & Maintenance Booklet

From my wife’s mazda’s manual:

“Caution. After driving at freeway speeds or up a long hill, idle the engine for 30 seconds before stopping it. Otherwise, the turbocharger could be damaged”

 

Nobody reads the fabulous manual.

 

What if you are driving at highway speed in a turbo Mazda take your exit, that has a stop light at the end of the ramp and your very same Mazda has auto start/stop will the engine idle for 30 seconds before it shuts off?

 

It doesn’t have start/stop

 

Solves that problem.

 

I am very surprised they cant just build a turbo timer into the truck. You can start the thing from an Apple watch, why cant it just idle itself for 1 minute and shut itself off after you walk away?

 

Because it virtually never needs to happen, and people would be frustrated by a vehicle that “won’t turn off!”

 

I can't agree. A lot of people look for the manuals online. Others are ready to pay for the used ones. I was surprised by the prices and ended up looking for it online. I was lucky to find it here toyotamanuals.org and can quickly check it when needed.

 

I always read the owner's manual (well, the maintenance schedule) before buying a new car to see if there is anything weird/expensive.

Like the new Tacoma needs plugs every 40k and has separate coolant for the intercooler. Just things to be aware of.

I wouldn't buy a VW with a DSG transmission (pricey fluid changes) and would mentally have to file the cost away for a $1000 timing belt job at 100k miles.

 

This isn't Toyota's engineering, it's a common recommendation by most auto manufacturers for their turbo engines. It's obvious you know little about modern engine design and maintenance. Can't spare a minute?

 

You don’t even have to. The time spent turning into a parking lot or going down your residential street will more than cover the cooling time. How many times have you gone from highway speed to engine off without ~1min of slow speed or idle time? I can’t remember even one for me

 

Good point, more so in the winter though. Triple digit weather, towing, long steep passes then otherwise.

 

Ive never pulled a long steep pass and then slowed to a stop and shut the truck off within 1minute. Just pulling into a parking space takes almost all of that time easily. And if I stop on the side of the road at the top, I just don’t shut off my truck

 

This thread is pretty entertaining.

As a previous poster pointed out... the idle time to allow oil to continuously flow through a hot (1100 Deg F for some) turbo after lengthy pulls with boost isn't anything new. Almost every turbo diesel engine requires this.

It's not very often it happens, but I've had to do it a few times where I'm pulling a trailer with our 6.0L diesel and have had steady EGT's of 1000 Deg F (usually 1200 is the danger zone) and pull the truck over into a gas station or rest stop.

Pretty obvious when you are in the boost for a prolonged period of time... you just need to sit in the cab for a minute or two to let the oil pump circulate oil through the needle bearings in the turbo.

There used to be some programs / tunes in the diesel world where you can set a idle time to automatically shut off the engine if it senses EGT temps above a certain range. Not really needed if you just pay attention.

This isn't a major deal.

I would be curious to see how the turbo holds up for long term service. They hold up fine on diesels... just hope Toyota did their homework and did sufficient testing.
