Well, you hit all the high spots in maintaining that engine. Those Aisin kits are awesome. Completely OEM parts for a Toyota and a good price too. Aisin isn't the OEM water pump supplier for my Accord, but I bought one of the kits anyway based on my past experience. It was of very high quality, everything made in Japan.

And yes those spark plug wires are ready to install which makes it easy.

Amazon has a great price on an OEM Aisin TB kit (TKT-024) which includes the hydraulic tensioner and idler bearings. All the other OEM stuff came from a dealer in VA and it didn't add that much to the cost vs. aftermarket items. The nicest thing was the plug wires that came already loomed.

Now hopefully all I need to do in the next 112,000 miles is change oil and filters.

I have an OEM set of heater hoses (engine to heater coil) if anyone is interested. PM me.

Thank you. 3-4k OCI's, regular PCV changes, air filter changes, and TB kit every 90K (+/-). Ready to run to 300k before the next heavy maintenance. Also did the KYB quick struts all the way around. Very happy that I went with KYB, what a nice firm ride.


Has your TB looked worn at 90k? I have been going by the original owners manual supplement that only calls for a TB replacement, at 90k, for "heavy commercial use". Otherwise no apparent replacement recommended. I plan to only replace when the water pump needs replacement.

The supposed sludge monster V6.

Yes it would sludge. But I suspect only if you pushed OCI to the limits or beyond.

Nice job!

It has looked great both times. First one was done right at 90k and the second one at 187K. I plan on going 112k on this one. The valve covers and cam seals needed done badly. That was the main reason for this TB job.

You're going to wait for a water pump failure? That's one component I'd rather not wait till it fails.

The belt itself usually looks pristine at changeout. However, the idler and tensioner pulleys will fail before the belt.

Thanks for the info. What time or mileage is your experience on idler/pulley replacement?

A complete OEM kit (Aisin) can be had for $140. Why not just buy the kit and replace at every TB change? It's cheap insurance.

Well, the one time I didn't change the idler and pulley with the belt (the first change) it failed about 20,000 miles later. The engine started making a knocking noise at a certain RPM, almost like rod knock (the pulleys are bolted directly to the head and/or block). The dealer in town diagnosed it for free for me when I had it in for something else. The tech pulled back the timing cover and as the engine was revved, you could see the idler "hop" or wobble when it made the noise. He said it was common if you didn't replace the pulleys at the same time as the belt smile

And I agree with the comment about buying the Aisin kit and putting it all in. You can't go wrong with that kit.
