before takin off the belt make sur you can locate the belt map on the hood or under the hood near radiator fan shroud(cover if the is no map label you can draw your own diagram of the pulley sysrem draw it as close as you can then draw the way the belt goes around each pulley look hard for a label it is drawn with multiple circles and a black band (your belt routing diag. there is usually one main spring pulley and tensioner that holds the belt a a specified tension automaticly. if you dont know which is you spring tensioner you can put on a glove make sure car is off grab the belt firmly and pull hard the belt will give a bit while you are pulling on belt stare at the pulley that is move back and forth this is your auto belt tensioner. look at the pulley and arm closely it usually has a squre to accept a 3/8 or a 1/2 inch breaker bar or retchet wrench if not equipped with said squre hole use a wrench to fit the bolt that goes through the pulley never take bolt off other end as this bolt will remove the tensioner a possibly the spring causing injury pull on tensioner until it springs and belt start to slacken unhook belt while still holding pressure on tensioner with other pull belt off a top pulley a slow release tension pressure noe unsnake belt remove run new belt according to map pay attention that the grooves are completly on your pulleys snake the belt until one top pulley is the only one left lift on tensioner this will give you the slack you need to pull belt over last pulley. release tensioner now go to every pulley and make sure belt is completely on pulley one tooth will cause belt to fly off or premature wear p.s always measure old belt to new belt or it will drive you nuts trying to put a smaller belt on also count the ribs any questions email good luck g i looked online and you will need a socket or box wrence to puul on yensioner another waay to locate is it is about 4 inch pulley with no belt groves and about 3inches away mounted is the round spring housing. just look up replcement belt tensioner online to give you a photo of what your dealing with
It has a chain.
The 2007 Subaru Tribeca does have dual timing chains.
Timing chain.
timing belt.
Timing Belt, and a serpantine belt
105,000 miles
with your hands...
On a 2.5 liter engine it is located behind the timing belt cover.My advise, replace the timing belt when you replace the timing belt. It will have to come off anyway.
If its from the engine bay, check the serpantine belts, and the timing belt. My old Toyota paseo had a bad serpantine belt and it did squeak alot. Also check all the pulleys make sure theyre not wobbly.
They have a tensioner that automatically tightens the belt, maybe yours needs to be changed or you need a new belt.
Never use belt dressing on a serpentine belt. Clean the dressing off and recheck the pulleys.
Replacing the timing belt is a complicated procedure that is impossible to describe in this small space. The engine in your Subaru is an INTERFERENCE engine. As such if they belt is installed incorrectly and you start the engine you will do damage. I suggest you purchase Haynes or Chiltons repair manual for your car. It will describe in detail with photos how to replace the cam belt.
