Timing Belt 02 WRX

tellravi · 08-19-2003, 02:33 PM

All,
I may get some Engine Work done to my car. I have 29K miles on the car, would you recommend I change the TB anyway.

If YES, would you guys recommend any after market ones which are stronger? PE sells one.

Finally, is there anything else I should change while the tech has the engine apart.

Any recommendations

Thanks

The service interval on the timing belt is 105K miles. At 29K it should still be like new. If it's going to be off/apart inspect it and change it if you want, but a new stock one is all you need if you do decide to change it.

Thanks for your reply

Definitely 105K replacement interval with inspections every 30K. The same goes for the accessory drive belts although those are easy to inspect more frequently and cheap enough to change well before 105K.

We recently had an 02 wrx that had the belt jump at 26k. If its off, change it. All you get is 3 teeth before the valves are damaged, so better safe than sorry. You can get an STI belt from the dealer for the WRX. It is slighty noisier, but stronger.

What was the cause for the belt jumping? I'd assume something went wrong with the tensioner to allow that to happen since the belt itself should still be in excellent condition at 26K. If the belt actually failed it would be unusual.

Tensioner had not "failed", but was replaced as a precautionary measure. This car had an 18g on it, and was overboosted a time or two from what the cust said. I had a chat with AZ Scoobie, and he had some good possible scenarios, including speed shifting and a lack of a guide on the intake cam on the drivers side. Seeing a timing belt actually broken is very rare, they tend to jump rather than break, sometimes getting chewed in the process. SO basically, keep an eye on them.

What is the easiest way to inspect the belt without disassembling everything? Just take off the timing belt cover?
