Timing Belt Change How-To

This link used to be in the old forum. I know its a popular topic so I figured that I'd post the commonly referenced link. It is for a Camry, but the procedure is the same.

Nice! I'll use this post as a reference for my TB change tomorrow. I'll let everyone know my experience with the job.

Re: Timing Belt Change How-To

Dloomis,

Any updates on the Timing belt change? Did you change the water pump as well or just the Timing belt?

I'm looking for that pdf on the metal bracket someone fabricated to help remove the lower pully bolt.

What special tools did you use/fabricate McGyver to get it done? I'm planning on doing mine this summer. I have 172,xxx kms (106,xxx miles) on mine original TB now.

Regards, Jason.

Re: Timing Belt Change How-To

Does anybody have a good set of instructions on making a bracket to remove the crankshaft pulley bolt?

I want to tackle this job myself this summer.

Regards, Jason.

Re: Timing Belt Change How-To

I remember that post from the old board.

However, I have one of these and it works great. It is under $70 and it works, no chance of breaking it and damaging something else:

Re: Timing Belt Change How-To

I used this --->http://www.sears.com/shc/s/p_10153_1...ord=otc+toyota

I already had it and just ran bolts thru the holes on it to hold the crank pulley. You can see by the picture that it wouldn't be too difficult to fab one up out of some 1"x1/4" strap steel. Just make it long enough to wedge against the subframe because at least I couldn't hold it by hand while breaking the nut loose.

Re: Timing Belt Change How-To

Thanks Rust Heap and kschachn.

kschachn, How does that pulley holding tool work? Does it attach to a breaker bar to work?

Do you need that and a separate breaker bar to get the bolt loose?

And lastly, does that tool work to re-tighten the pulley bolt when reinstalling the timing belt?

Are there any other special tools that are needed to remove any of the other bolts?

Thanks in advance.

Regards, Jason.

Re: Timing Belt Change How-To

Yes, you use a standard 1/2" breaker bar to hold it steady. Get a big one, the larger it is the more leverage you get. Even a Harbor Freight bar should be fine.

You use the two bolts to attach it to the flywheel and then use a breaker bar to hold everything steady. It holds the flywheel steady for both removal and installation.

You'll need a 10mm socket-type allen wrench to get one of the the guide pulleys off, if you are changing those at the same time (I would recommend it).

If you're also putting in a new water pump then you'll need another tool to remove the camshaft pulleys. Here too there are commercial tools or you could use something homemade if you are handy.

Re: Timing Belt Change How-To

I know I'm opening myself up for criticism but here goes. . .

I did change the water pump, I didn't have faith it would last to almost 200,000 miles. I did NOT remove the cam gears to do this. For those that don't know, there is a plate that goes behind the cam gears but hangs down and blocks the removal of the water pump. I reached up behind it and found no supporting structure where it blocks the water pump. I just cut that part out with a 3" cutting wheel. It may sound hack, but it worked for me. YMMV

Re: Timing Belt Change How-To

Hi Everyone,

I'm making a trip to the good ole USA at the end of the month. The land of more affordable auto parts.

I want to tackle the changing of my timing belt on my Sienna.

What special service tools should I purchase to do the job with minimal cursing and swearing once I have everything apart? Will the pulley slide off easily once the bolt is removed or is something special needed as well to remove the pulley once the bolt is off?


I found an interesting link on youtube for a home made pulley tool for a 4 cyl camry.

Any advice would be appreciated. I'm looking at doing the water pump as well at the same time.

Regards, Jason.

Re: Timing Belt Change How-To

To Anyone Changing Their TB,

A good impact wrench is worth its weight in gold for removing the crank pulley bolt. I just changed my tb out about two weeks ago, and I had trouble getting the bolt loose. I borrowed a Matco impact from a friend of mine and did nothing but rattle. I debating on buying the pulley holding tool, but decided to buy a bigger gun first and see if that did the trick. It made more sense to spend a little more for a tool I'll use over and over again than buying a tool I would use only once or twice. Here is the impact that I bought.

http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053

I had to turn the pressure up to about 125psi to break it loose but it did the trick. Wouldn't have guessed that the HD wrench would outdo a Matco, but it did. Hope this helps.

Rdnk454,

One more question, did you drain all the coolant when you removed the water pump? Or did you just remove the pump and let the coolant which was up at the water pump spill out?

Re: Timing Belt Change How-To

While impact wrenches are often used just to speed up the work, there are some jobs for which they fundamentally work a lot better.

I have rented an electric impact wrench to remove the crank pulley on one of our vehicles (didn't have an air compressor), and I eventually bought one when they got cheap, but I would be prepared to rent again if a particularly demanding job was too much for the tool I have.

The Home Depot tool is of the Husky brand. I had never heard of Matco and didn't know that the Husky brand included air tools, so I guess I wouldn't have an expectation either way.

The Matco impact wrench lineup has a dozen or so 1/2" drive models, with rated torque from half that of the Husky (a compact/lightweight model) to much higher (1,000 lb-ft versus 650 lb-ft for the Husky). I think just the brand is too much of a generalization for a useful comparison.

Re: Timing Belt Change How-To

I drained as much coolant as I could via the drain on the Radiator, then let the rest spill out into a basin when I pulled the water pump off. Not the best way to do it, to be sure.

Re: Timing Belt Change How-To

Just FYI...
[Matco] is a competitor to the probably more widely known [Snap-On] brand of professional automotive repair/service tools. They have their own regional distributors/sales & service force that drive around in service vans and go directly to shops.....similar to [Snap-On].

I see both in my area from time-to-time.

YMMV.
