timing belt - 03 sport

[mooockie]

I have an 03 sport w/ 4.7 v8 and am nearing 90k. What should be replaced besides the timing belt itself? Some say the water pump others say not needed. Also, what about tensioner and pulleys? Basically, I'm looking for a parts list of what I'll need. Also, anyone know a good source pricewise for the parts.
Thanks.

Since you have to pull the water pump to get to the timing belt, you might as well replace the water pump, too. Easier to do it while you're in there than to have to go in later.

Don't think you'll need to replace tensioner and pulleys, though.

This might be a dumb question, but does the 2003 V6 have a timing belt or chain??

Thanks!!

V6 uses a timing chain.

Chain, no regular servicing required.

I didn't know this until I got a newer 4Runner, but if you open the oil fill cap of the 4.0 V6 and look inside, you can see the chain. Don't try this a night though. :biggrin2:

Any recommendations for vendors to get these parts at for a reasonable price?

If you look under "Maintenance", you should be able to find a lot more info. I recently had mine replaced, and got my parts online.

Do we really "have to" replace them at 90K miles (even tho there's nothing wrong with it)? OR do they breakdown (start cracking) at that 90K point?

The answer to that question depends on if your engine is an interference engine or non-interference engine. If your belt breaks in an intereference engine, you stand a good chance of bending the valves. When I bought my Acura Integra in 88 I went back to the service department and saw a 86 with 72,000 miles and the belt broke causing considerable damage. The recommendation of that vehicle was 60,000 and I pretty much stuck to that recommendation.

The 4.7 V8 is an interference engine.

I've heard of a few guys taking it up to around 100k miles or so before changing the timing belt out. But it really felt like I was gambling the longer I took it past the 90k mile mark. I had mine replaced at 94k. It was like there was a ticking time-bomb on my wallet that could go off at any time.

The truth of the matter is it probably could have gone quite a bit longer. Although, when I inspected the removed timing belt, I did find some areas which showed that it was starting to wear. This may have been occurring over a long period of time and may have lasted a bit longer, or it may have been in the stages of breaking down. There's no telling.

All-in-all, I am glad I got mine changed out when I did. I also think I would have been biting off more than I could chew by doing it myself. So I had a reputable shop do it here in Little Rock, and it was considerably less than if I was to have the stealership do it.

I ordered the parts online and took them with. I know I'll get flamed for this, but one thing I wouldn't (won't) do again is buy the coolant at the stealership again. What a crock! I know many on here will swear by the Toyota coolant. After having the work done on my truck, I looked into it further, and what I read in one of Toyota's procedures was to use their coolant, OR another high quality coolant which met certain specs that were listed (phosphate free, etc - I can't remember specifics on it). After reading that, I checked many different brands, and quite a few met or exceeded the criteria.

So how much does the stealerships charge you to replace this?

I've gotten quotes of $500 for timing belt only from stealer.

For parts I have found the following:

tb kit that includes the belt and bearings for the tension and idler pulleys

hydraulic tensioner

At the same time I will be doing the water pump, gasket, inlet pipe o-ring, water bypass pipe o-ring.

Is this all I need?

I can't believe some of you guys are getting quotes of only $500 for the timing belt R&R. I went to the two dealerships here and one quoted me $980 + tax, and the other quoted almost $1200 + tax to change out the timing belt, and the water pump. Labor alone was going to be $500+!

I got my parts from www.1sttoyotaparts.com. They had the overall best prices I could find. Quick shipping too. The water pump came with a gasket, but I purchased the two o-rings at a local dealership. Along with the t-belt and water pump, I had the tensioner changed out too. You could also change out the idlers if you feel the need. My mechanic checked them and said they seemed fine. I just felt it was a good idea to change out the items I had changed out.

Mine is coming up on 90K miles, and the dealer quoted me $1000.

Is there any tranny of diff or transfer case fluid change at that time as well?

A/V1 is right, you guys are getting ripped if you take it to the stealer. Like A/V1, I got my timing belt, pump, and serpentine done at a trusted shop at 97K. I was very paranoid, and it was like a ticking time bomb. All in all it was around $560. The water pump alone was around $125, and he used Gates belts, and a pump from NAPA. No tensioner or pulley. So far so good, no Toyota red long life, just the green stuff. I am still rolling strong, just hit 115K. Spark plugs are next.
