How to take care of your Turbo

"How to take care of your Turbo"

"throw entire vehicle in the trash" - 2nd genners, probably

 

Yeah… LOL. And when it’s really cold, her Camry at startup is idling at like 2,000…. She does a reverse neutral drop.

 

I’d click that YouTube video

 

TJ, I think the technology behind the Toyota turbos is that they do not spin until the waste gate opens up. In other words they are not spinning Until the engine demands extra power the turbo in not spinning. Also the twin intercoolers continue to cool both turbo's at shutdown. Think that Toyota thought out their design pretty well. Also I do like the Care Care nut.....would love to hear The Car Care Nut address the 3.5 engine main bearing failures. For now I'm changing my oil every 3500 miles and hoping for the best.

 

That would be like watching Archie Bunker on a continuous loop at high volume.

Blooarrrghhhh! I'd rather have my toe nails torn out. Come to think of it, I do read second genner's whining posts here in Archie's voice now!

 

Have you owned a turbo engine before? A turbo is ALWAYS spinning. A turbo is driven by the exhaust. And a wastegate is exactly what it implies. It opens up to let waste exhaust out so you don't build to much boost. It regulates the boost pressure. Intercoolers don't do anything once the engine shuts off. It cools the intake charged air before going into the engine. Please tell me your post was sarcasm because I feel like Billy Madison right now.

We all have to learn sometime. I’ll add a tad more for @Kanadakid, our V35A-FTS Type 21 engines only have a single liquid-to-air intercooler shared by both turbo outputs though there are two radiators up front used in its cooling system. That system has an electric coolant pump cooling not only the intercooler but the turbos themselves. The wastegates are electrically actuated (the part that failed in early 22s) and dump over pressure air back into the intake. Not into the atmosphere like some vehicles do.

 

Just look at the information cluster on your dashboard. It shows you when the turbo in engaged and when it is not engaged. The turbo chargers are on demand and electronically controlled.

 

Be careful what you read on the internet folks. This is not true. I’m positive this is either a gross misunderstanding and misinterpretation of information on the posters part, or an attempt to get a rise out of folks by blatantly posting false information about turbos and how they work. Either way, disregard these statements.

 

Could be he's thinking about the Porsche E turbos but that system isn't in use on the Tundra. Very complicated but it's an interesting way to cut lag. On that system there is a bypass valve.

 

If the engine is running the turbos are spinning that's a basic fact-they are directly in the exhaust stream. Boost is only built when the bypass valve closes. They don't spin as fast at idle or low demand but they spin none the less. Under boost they go from 20,000 rpm to as much as 120,000 rpm depending on demand (throttle position), engine load and rpm. There are snake oil salesman and ignorant advisors everywhere. The service advisor at my local Toyota dealer tried to tell me Toyota uses break in oil and the first oil change shouldn't be before 5000 miles. True or false if at 1000 miles the engine isn't broken in (aka rings are seated) it will never be...moral of the story is we have a highly stressed twin turbo engine that can definitely last the warranty on 10k oil changes but if your looking for a keeper change it a minimum of 5k intervals. Letting it cool for a minute after a hard run is just to let the turbos spin down and cool a little...insurance lol. Mine will auto shut itself off if it hasn't been run hard a few seconds after it's put in park. ECM knows better than me I guess.

 

You let your wife drive it????

 

Ha! Not on your life! She's relegated to the CX5.

 

The owner’s manual has a blurb on this fwiw…

 

Ford and others have been putting turbo motors in vehicles for over a decade. Many in vehicles with owners that never even check their oil and skip maintenance by not paying attention yet there are no massive turbo failures being reported. How many are in fleet vehicles?

Think most folks are following a "let the turbo cool off before shutting off" practice? Most don't even know they are driving a car with turbos in it.

That is because these newer turbo motors have been designed to be turbo motors and the engineers have put in systems to overcome the "average" driver's lack of paying attention.

Notice the caveat? High speed driving or hill climbing?

 

So say i drive at highway speeds for awhile then get off and sit at a stop light for a minute or two, am i good? Lol

 

It says right in the manual that failure to do so may result in death or injury! Most of us should be dead by now.....

 

Guys I just left a shop that does all the warranty work for a used car dealer as well as get ready for sale. Every F-150 turbo over 80k has an internal oil leak that fills up the boost hoses and eventually the intercooler. The Escapes, Fusions, Ecosports, Buick Encore, Chevy Malibu eco, etc... 9 times out of 10 have a bad turbo. Probably from lack of maintenance but facts just the same. The factories make them just good enough to most of the time make it to 60k powertrain warranty if oil is changed every 10k miles.

 

Weird, F-150 ecoboosts are the main fleet truck for the gold mines in Nevada yet we never hear about this with 150+ ecoboost F-150's with over 100,000 miles. Plenty of cam phaser repairs on trucks pre August 2019 production, but nothing with turbo or intercooler issues in my experience.

 

We saw plenty of cam phaser issues DFS but most of the vehicles come from dealer auctions aka trades new car dealers don't want. Most people don't give a crap. I have a friend that buys off lease Nissans with 20-30k that have a voided engine warranty from Nissan due to sludge...when folks lease a Rogue or Altima on a special they don't do anything but put gas in it...forget oil changes. You maintain a fleet and probably invest in oil analysis. But to your point when we occasionally get a well maintained Ecoboost F150 and they are fine unless the waste gate starts sticking or hanging open causing overboost or underboost. Usually a little over 100k miles.

 

Now would I buy any Turbo motor vehicle with over 125,000 miles on the odometer?

Depends on the maintenance history and manufacturer's history. Anything from Stellantis (Jeep, Dodge, Ram, Chrysler) are immediately off the that list. Way too many issues with that manufacturer.

Before purchasing my 2017 Ford Expedition with Ecoboost 3.5L. I did see high mileage ones in the F-150 forums. That is where it was logically explained to change your oil, air filter and even spark plugs earlier than normal for longevity. I still bought a Ford factory extended warranty though.

If I see 10,000 mile oil change intervals, I will not be buying that vehicle used, even a Toyota.

 

cmiles97 you are a smart consumer. You value records of service. For better or for worse CarFax and Autocheck are the best resources out there because most people don't keep a record any more you'll be lucky to see that info unless they consistently went to a shop that reports like Valvoline Quick or Fast Lane Oil Change shops or believe it or not Walmart.

 

Buy the extended warranty, service the vehicle according to the manufacturer schedule , sell it at the expiry of the extended. Problem is never yours.
We live in a world of disposable parts and appliances

 

1000000% This. @Eurodriver FTW - Not all heroes wear capes!

 

you are shitting me right?

 

The pistons/rings are pretty much already broken in at the factory. Its everything else that the oil contacts.

 

Wait till he has to take the cab off to get to anything.... Retirement time!

 

Anytime someone says this it makes me think of my old coworker's response:

"I wouldn't shit you, Hella Krusty. You're my favorite turd."
