Second timing belt change milage? (2004 Outback Sport)


Recommended Posts

105,000 mile change interval.

 

If the pulleys and tensioner have never been replaced, best to do it soon, or whenever you can get around to it.

 

These timing belts are fairly robust but if a pulley or tensioner fails then the belt breaks or slips and you have bent valves in the engine since yours is interference.

 

Ebay timing kits are $160 - $200 for the pulleys/tensioners. PCI kits or theimportexperts are good choices. The site administrator here can get decent prices for Subaru OEM parts and ship them to you, contact him here:

If you use a kit with a water pump, be sure to buy a Subaru water pump gasket, the aftermarket ones suck. And use a Subaru thermostat or the new XACTA brand available aftermarket.

 

A typical thorough timing belt job includes (due to access):

Timing belt, tensioner, 2 idler pulleys, 1 toothed pulley

Water pump and thermostat

Reseal oil pump and tighten the backing plate screws (usually some are loose by now)

Cam seals

 

Timing belt has to be removed to replace all of those and they're cheap so many folks just do them all at the same time as preventative maintenance for long term, high mileage reliability.

 

The newer seal material and EJ water pumps are robust and not necessarily prone to issue but 200,000 miles is a lot for either and wouldn't be a surprise to have issues at some point on these consumable items.
