Hit the 'ol 200K...any maintenance tips to look for?

Turned the rig over last week.
2019 with 200K and nary an issue lately other than some assholes dinging the rear bumper.
Question is are there any big ticket items I need to be cautious about?
Water pumps, timing belts, etc.....

 

Depends on how current your truck is on the maintenance schedule in the manual.

How’s your transmission? Belt? Hoses? Have you ever done a coolant flush or changed your power steering fluid?

 

200,000 miles! I'd say keep doing what you have been doing.

 

Right on man, love hearing you haven’t had any issues lately. Keep racking it up!

 

Is this without a transmission cooler?

 

Your truck is a 2019 so it has a timing chain engine, not a timing belt so it is not a maintenance item. Water pump would be replaced if it is leaking, also not a normal maintenance item like it was on the old timing belt engines.

Aside from sticking to all the normal routine maintenance items detailed in the service manual, I think replacing the radiator cap and PCV valve every 100k miles is a good idea. They’re cheap and easy parts to replace. PCV valve can start sticking when it gets old and the radiator cap has a rubber piece that likes to break off and get stuck in the upper radiator hose and restrict coolant flow.

 

Wondering the same thing

 

My truck does have the tow package however the 2019-2020 Tundras did not come with tranny coolers.
I see there have been several old posts here about this omission by Toyota.

 

Oil change intervals? What oil and weight?
Front and rear diff change intervals? Transfer case fluid?
Transmission drain and fills at any interval?
Coolant changes at any interval?

For bigger items:
Did you change the spark plugs? Water Pump?

Please post more. This is pretty high trouble free miles for a 2019.

 

To be honest.
I 1st swapped plugs out at 100K
Believe it or not, I'm only on my 2nd set of brake pads and rotors.
Synthetic oil per specs at every 4-5 K
Have not done anything as far as front and rear diff cases or transmission drain.
Nothing to coolant either. Just checked all fluids at every 4 K.
Nothing on the water pump.

Truck is 80% road-city miles. Very little off roading for camping- hunting- fishing.
Trailer hauled maybe 10 times.
Bed is used all the time- light loads- materials. Projects.

Only thinks bugging me lately is a flapping-clanging sound under the truck while on the interstate at 65-80 mph.
Been trying to locate that damned cause. Running board or some plastic shroud?

 

Oxygen sensors are also past due, replace all 4. Better once's lifespan is 150k miles, then they start to degrade, engine computer does not get numbers it needs to see, power drops, MPG drops, catalytic converter temp raises.

 

Oh boy. 200K on the coolant? The Car Care Nut isn't going to be happy to hear this!

 

Noise may be a skid plate or heat shield.
I would flush power steering and coolant for sure.

Also check your radiator…I replaced mine on my LX570 and noticed it had accumulated enough debris on the front side near the top to block some airflow.

When the radiator is out, it’s easy to reach pretty much everything on the front of the engine, so I replaced the water pump, thermostat, fan pulley bracket, tensioner pulley, idler pulley, and serp belt before installing the new radiator. That was at 8k miles ago @ 176k.

Before flushing coolant, inspect your radiator hoses. It may be worth your time to replace those as well. If you just drain from the lower hose, you won’t get all the old coolant out of the engine block which isn’t the end of the world. Getting it all out requires pulling a drain plug on the engine block.

Refilling coolant:

1. Add coolant to the radiator. Do it slowly. (Mine took about 1.5 gal before it started overflowing).
2. Add coolant to overflow reservoir. I went to the F line.
3. Start the truck. Let it fully warm up, idling at 2k rpm. Once fully warmed up, turn the truck off.
4. Take a heavy towel, and turn the cap until steam hisses out. It’s now safe to add more coolant.

You might repeat steps 1, 3, and 4 two or three times. This is how you “burp” the system.

You probably don’t need to repeat step 2. The coolant you added to the overflow reservoir won’t be sucked back into the radiator until you let the system cool itself down without opening the cap. I have been watching temps on the Fusion app on my phone using a Veepeak Bluetooth OBD reader to make sure I got it right.

 

OP has to watch his video 10 times to make CCN happy again.

 

Not sure it goes that high but here's this

 

Why front diff OCI is 1/2 of rear diff? "Normal" is 2WD, front diff is not loaded at all.

 

I’m in the same boat so great to hear of someone without the cooler hitting high miles without touching the fluid or adding a cooler

 

When did 200k become a high miles for V8 Tundra?

 

Would replace the front and rear diff fluid, transfer case and coolant. See the above post for the coolant swap. The front and rear diff are very easy to do. Someone with much more knowledge can chime in about the transmission fluid.

 

A bit more difficult than engine oil because filling port is obstructed by exhaust/driveshaft. Two heavy steel skid plates / cat protectors also do not collaborate. But you have to do it once 20-30k miles.

 

Most people would consider a vehicle with 200k high miles. I get it though, the tundra has had many instances going well past 200k and I’m sure OPs truck will continue racking up miles

 

Per car care nut, go ahead and do a coolant change and every 50k after. Don’t run the 3UR at 100k coolant intervals

 

I'm not too sure I agree with this chart on the diffs. Seems backward to me on the front and rear intervals. I didn't change my diff fluids until 60k. When I drained it was obvious the rear diff needed it and I'm going to do 30k from now on on it. The front diff fluid looked almost as good as what I refilled with and smelled like fresh gear oil. Wasn't hardly anything on the magnet, unlike the rear. I don't drive hard, I tow very little and not heavy (there might have been 1500 miles of towing no more than 4000lbs on it in that 60k) and I use my 4WD on occasion. I have no problem going to 60 on the front diff after what I saw in mine; maybe I'll regret that at some point, who knows.

 

Some great info guys!
I do have a Toyota only mechanic right down street from my office. Not a dealership guy. He drives a 2011 Tundra so he's very familiar with the truck.
Ill have him do the once over and I'll bring up these fact-oids.

Thanks
