Timing Belt Question

The previous owner of my 4runner had the timing belt dont at 73,000 miles. The truck now has 106,000 when should I replace it again. I heard it was 90k increments? It is a '99 sr5 4wd.

Right 90,000 but many tend to go further, since it isn't an interference engine and the belt tends to last. I have 111,000 on mine. So, to answer your question, you have 33,000 miles on the new belt, wait another 100,000 miles.

Be aware of how your water pump is doing, as that can really mess up a timing belt.
 
Exactly, you have a ways to go. Get it serviced regularly and should the water pump leak, do the timing belt while you're in there. Additionally, don't forget to do the Camshaft seals and crankshaft seal.
 
There isnt any reason to do all the seals if they arnt leaking. I know some people like to replace every part behind the timing covers when they do the belts but it is entirely unneeded. If its not leaking, broken, worn out ect ect, there is no reason to replace stuff. Every 90K + for the tbelt and belts and check the other things and replace as NEEDED

I understand what you mean, most certainly vehicles with 90K don't need the seals to be replaced. But, vehicles with significantly higher mileage is highly reccomended.
 
i agree and disagree w/ you both! lol .... my own vehicles, i only replace what is needed. For a customer i would recommend to replace the seals, because the seals are far cheaper than the labor to tear it down again. Same could be true for someone if it is their only mode of transportation. The downtime may be better if it is planned in advance rather than if its oh %$#@ my water pump just went out and i have to work tomorrow!

When we get a vehicle in for a job like this, we will tear ti down and check everything that needs to be replaced. If the car has over 200K and has never had a w/p, then we will give the customer the option to replace it if it isnt leaking. If it is leaking, of course we will recommend they replace it. As far as the seals go, especially on the 3.4's, they usually arnt a high failure rate part so they are rever recommended unless they are leaking. I guess if you have plenty of disposable income and want to replace it all, thats your choice. I guess I see it a bit different than someone not in the business especially since it only takes me about 20 mins to tear a 3.4 down to the tbelt

Yes. Been in the business on toyota's for about 12 years now. Any california people that need work done can let me know as I do a fair amount of side work

I don't consider it a good idea to wait until the part fails to replace it...

Ok well where do you stop then? Your eng could blow or your tranny could get noisy or anything on your rig could fail. I guess you could replace the car if you are that worried about not letting things fail

It comes down to two point of views:

1. We are in the business, we have the means, the tools, and finally the knowledge to repair our own vehicles should bit by bit fails.

2. Like many people here, they don't have the means like we do to repair their vehicles. In the end, it's THEIR best intrest to get it done.

hey toytech76... where about in northern CA are you located? i'm in the east bay and would definetely consider throwing you some cash to help me fix problems with my car in the future.

if thats even what you were talking about...

i really enjoy working on my rig, but like the peace of mind knowing someone who has 1) done it before, and 2) actually knows what they are doing, to be there.
