I understand that our cars recommend a timing belt change around the 80-90K mile range...but what about afterwards? I am just about turning 125K miles on my car now. Does this mean that I should do ANOTHER timing belt change around 170K miles? Let me know, thanks!

 

Seems pretty logical to me. If the service manual only went to 150k, you wouldn't stop changing your oil after that just because its not listed.

 

Seeing many timing belts (which are now better made than two decades ago), most of them still look 90% new. If yours doesn't show cracking then chances are, it's still has some good life left in it. Water pump and tensioner are the same thing. The OEM parts are damn well made. My TB/WP was changed at 90k, but I think I'm going to push the next one to 190-200k instead of 180k.

 

Bought my car with 83k changed the timing belt @ 90k & then @ 175K & the belt still looked great. But you dont chance it with a interferance motor.

 

Got 95k on 02 GS300. Planning to do mine in January.

 

98 gs 400 id change mine at 90k

 

My 98GS400 had 120k on the odo when i got my service done.

Ill probably do it again around 200k

 

Do it every 100k. The belt could definitely last longer but there's no reason to take a risk, especially with a part like the timing belt.

 

Just wait for something else to go wrong that requires you to disassemble a lot of shi, to the point where you're close to the TB, and replace it then

 

Aah the ol' let it blow the f$%k up maintenance plan I see no reason not to replace it every 90k, it's not expensive and not very difficult.

 

For owners that do their own work this is how I see it... on the belt. Skipped the water pump and tensioner bearing and idler bearing on 1st go round. Now I am planning all items except tensioner which should be fine.

At 175k I am thinking about pro-actively changing my starter and fuel pump. Two items that are labor intensive to get to and can leave you stranded.

As far as intervals on the belt... the OEM is definitely good for 100k with aftermarket items being unknown. Got a Mitsuboshi (yes boshi) with a Tundra WP kit using the OEM Aisin WP. Not sure about this belt but I have it so will run it. Bearings in kit are made in Japan.

Unfortunately at this mileage a whole BUNCH of stuff could be replaced pro-actively. My radiator is now leaking around the top seal so ordered a Koyo which is supposed to be high quality even if made in China. Swapping power steering pumps for a lower mileage take off and will rebuild my orginal for backup. Alternator is original as is A/C components and freon. Wheel bearings original along with all rear suspension. Shocks are original and thinking Megan COs. CVTs and U-joints, driveshaft isolators, hoses, fittings, catalysts, HID balasts, steering rack, inner and outer tie rods, fuel injectors... LONG list. If it moves, heat cycles, corrodes, sun light, ozone... it will eventually fail. Nothing lasts forever.

 

No it doesn't unfortunately. Do the starters in these cars just die where you'd have to worry about getting stranded or will it at least give some warning signs it's on it's way out first?

 

It's sometimes random. When my starter was going out, it would only start half the time. When you turn the key, you'll hear a clicking noise but that's about it. Sometimes I had to try 3-4 times before it would even turn on. It could be working well for one week, and the next week it'll quit on you, and then the week after that, it's all fine. The process continues. Some people had it worse because they quit altogether without warning.
