I just rolled over 200k, timing belt?

[Mike6158]

Based on the PO's maintenance records the timing belt and water pump was changed at around 95k. Should I be ordering parts to do the same at 200k?

Does anyone else get a little disappointed when they miss the rollover I noticed that I had 48 miles to go and then got caught in some I40 repair traffic (and going around all that mess) and forgot to watch for it.

The last oil report was sent in a bit early. They recommended 14k and I switched at 10k due to what I thought was going to be a long trip. Report attached

It's a 90k service interval, so I'd say yes, order the parts and get it done. Of course, I've heard tons of stories of timing belts that went WELL beyond the 90k (one owner said his went 160k). For peace of mind though, I'd say get it done.

 

[Julian Stead]

If it's on your mind then yes. Nothing worse than beating yourself up if anything did happen. You just need to make your mind up about a fan bracket, water pump, thermostat, coolant hoses, heater tee's now,haha. Are you doing it yourself?

 

[Mike6158]

I did the upper and lower radiator hose when I changed the radiator. I'll have to take a look at the heater hoses. The tees have been replaced. Thermostat and water pump were on the list with the timing belt. Fan bracket?

By Monday I should have OME 2.5" (heavy) lift with diff drop and new UCA's, dual battery setup (trays, controller, etc), ARB compressor, and Slee rear bumper. Building it one piece at a time but this is the first major change.

Yup, doing the work myself. I already did the steering rack, wheel bearings, and front shocks. Chisto Slee quote (sort of): If you can change your steering rack you can do the lift, UCA's etc.

I wasn't really planning to do the lift anytime soon but things change. I'll have slightly used front Bilstein 4600 series shocks and NIB rear Bilstein 4600 series shocks for sale after I install the OME kit

You have got the bug, I will be replacing my AHC for conventional next year, I have just had my first AHC failure, but getting it repaired for now. I will be Overlanding Africa in the next year hopefully, so my list of modifications will begin shortly.

Good Luck with the work, better to do it yourself even if it is a learning curve as you gain more knowledge of how your truck works. There are to many bad stories and experiences from some so called professionals, so that is a risk in itself.

 

[Mike6158]

Overlanding Africa! Awesome. The best I can claim is driving to and thru the back country of Death Valley lol

I agree with DIY. I learned a lot of new cuss words when I installed the steering rack

 

[Julian Stead]

Africa is a dilemma though, I might have to buy a diesel version of the 100 as Gasoline is harder to get hold of, I will have to research more into it. Diesel for Africa, Gasoline for Asia I was told. I might of bought the wrong truck.

Timing belts rarely fail, it's the belt tensioner that fails causing the belt to jump teeth. But as long as you're in there...
Every 100k is more than sufficient.
Mine was replaced at 85k, I'm not touching it until 200k. I'm at 175,change now.

Get a comprehensive list of tb parts and consider each one. Cam seals, tensionser, fan clutch, fan bracket, etc.

 

[fooldall1]

For the record, I changed mine when I got it @ 215k... it had NEVER been changed to that point (there was a date stamp on the belt). It looked bad, but not as bad as you would think for almost 220k miles on the same belt.

THIS. I recommend replacing all of these at least once in the truck's life, especially after the first probably two changes. When I replaced all these things on the last timing maintenance interval, the engine was/is smoother and quieter than ever and performs great. Just food for thought, but might as well change them out of you have the chance unless you're working on a tight budget.

I'm at 166,000 and I don't think mine has been changed. I just the parts to do it this week.

 

[cwmoser]

I'm at only 38K miles on my 2002 LX470.
I know the age of the Timing Belt can be an issue now but I'm going to hold off for a while longer.
My thinking is that my 100 has been garaged much of its life and often times a belt breakage is
not a ruined engine. Maybe I be better off buying a Lottery Ticket

 

[bls72bmw]

Hmmm you fellas have me wondering-
I've a new to me 98 with 282k on it, completely unknown and undocumented service history.
Is there a way to tell if the belt has been done? I'm partial to just rolling with it and see what happens honestly; are there many cases of the belts snapping, or jumping teeth. It's a non interference engine right? So if the belt goes I'm just stranded but not a blown engine?

 

[Julian Stead]

People say it is a non-interference due to it rarely causing damage, but I did find Toyota literature saying otherwise, so they don't advertise it as non-interference. Overheating is the 4.7 biggest killer that I have read. So a timing belt job gets you to do more essential work that could be more important, like thermostat, water pump , heater Tees, hoses, coolant change. I done the lot in one hit. You can take the belt covers off to inspect. Make sure your Heater Tee's are good, if in doubt just replace them, I would rather risk a belt snap than these to go.

 

[milehighroller]

I changed my 2006 at 144K for the first time. I bought it at 138K. My water pump was leaking al little too. I can at least sleep well at night knowing I won't get stranded.

 

[r2m]

Should have been done at your 180,000 tick! Every 90k to 95k you should be doing your timing belt.
Yes you can wait longer, but why take a chance on ruining a great motor that will take you another 300,000 miles and further?

I don't mean to be disrespectful or antagonistic, but your original post is kind of a no-brainer.

@fooldall1 Reading this mileage I feel much better now, there are 80.000 mls on my LX, the belt has never been changed, so it's a 20 year old belt, I don't drive it lot of miles so hopefully it will make the 90.000 miles and 30 years (or not)

 

[cwmoser]

My 17 year old 2002 LX470 with 46K miles still has its original Timing Belt.

I had the Timing Belt changed (second time, previous owner changed it at 73K) on my son's 2004 Land Cruiser at 187K (114K miles on the belt). The replaced 114K belt was 6 years old and looked like brand new - no cracks, no visible wear.

I'm going to consider replacing the Timing Belt in my 2002 LX470 around 60K miles.

Here is another metric to consider ... I replaced the plastic heater hose "T" connectors on both our 2002 and 2004.
The 2002 T's came off solid and like new condition.
The 2004 T's came off and crumbled apart.
Considerations are 2002 pampered, garaged, low mileage.
2004 187K miles, 2 years younger, but put through more heat cycles. I'm surmising that deterioration of components like these Heater T's and applying to Timing Belts is more about heat cycles and exposure to heat and the flexing than age.

 

[super90]

Its all about the heat cycles on the T's....

IMHO
