2000, belt and pump changed recently at 85k. better safe than sorry.

 

edit: I had originally posted a reference to the "Gates Guide" (Gates is a manufacturer of engine belts). I've removed the link since the guide has been shown to be wrong.



Bruce... you're right, I did forget.

 

My dealership recommends timing belt replacement at 90,000 miles. I'm almost at 60,000 so they told me to wait a couple years. Right now to have it done there would cost $220.

 

If your not careful you will be changing the valves to tough guy.

 

One hour! ......I'd like to see that.
If you can even do it in 2 you'd make serious $$$$ as a mechanic.

 

I got mine done at about 96k. I was told by the Toyota dealership that the 3rd gen 3.4 liter is a NON interference motor. Anyone know the official word on this? I have 150k now and need to replace asap if it is an interference.

 

According to the Gates (Gates makes timing belts) guide link mentioned earlier, the 3.4 is an interference engine, the 3.0 is a non-interference engine.

 

That's my understanding too but I haven't tested the theory. The 3.0 only has 2 valves and the 3.4 has 4. My guess is that the 3.4 is a higher compression engine too and hence would be more likely an interference motor.
I just had the Dealer do the belt because I was lazy and was going to have them do an alignment anyway. Turns out they refused to do the alignment and already had the motor apart when they called me.

Something about too much lift and suspension changes. Whimps!

 

77K on mine

 

Intresting that that particular site says it's a interference engine and another site I found says it's not, I always thought the 3.4L were non-interference. I guess when I get the time I'll check with the spare engine in my backyard...

 

ok seriously, someones gotta get a straight asnwer about the 96-02 interface or non-interface. I have a 96 with 185km's on it, and wonder if i should change it at 200 or not.

 

The owners manual recommends replacing the T belt on a 3.4 at 90k miles.

It is an interference motor wo I wouldn't chance going much over 90k....its asking for an expensive repair.

 

how much did you guys pay to do your timing belts? I heard guys paying somthing like $500 to do that repair. I guess once I have that done, I might as well do that TFAL fan mod to.

 

The belt itself is about $35 online, or probably $60 at normal dealer prices. Figure 2-3 hours of labor, at $75/hour and you're at about $210-$285.

 

For what it's worth, I called 2 dealers here and they both confirmed the 3.4L as non-interferance.

 

I just called a dealer too and they said non-interference.

 

I follow the suggested intervals. Too expensive of a vehicle to chance it

 

It is a non interference motor.....not sure why it would be stated otherwise.

 

thats bs....half the dealers dont know what they are talking abot, why are we trustig them now? my dads friend who works at the toyota dealership by my house knows what he talking about and he said the vavles will get screwed up if the timing belt breaks

 

I wasn't talking to a salesman,I talked to the mechanics and two of them said no damage would result but who cares;I'm getting mine done this next week.
