To change the odometer from kilometers to miles in a 2007 Toyota Sienna, turn on the vehicle's ignition without starting the engine. Press and hold the trip meter reset button on the instrument panel. While holding the button, turn the ignition off and then back on. Continue to hold the button until the display changes from kilometers to miles.
You can't. The Sienna didn't have them until 2004.
you don't need to replace the timing chain until it becomes noisy
It is not necessary to change timing gears when changing a timing chain unless they have become worn. You won't know if this is the case until you get the cover off and inspect them. It is necessary to change any chain tensioners when you change your timing chain.
There is a bolt on the base of the distibuter loosen the it until you can turn the distributer and turn until timing is on. a timing light sjould be used but you can turn until the engine sounds RIGHT.
Depending on your specific year, make & model, it may vary. A 2000 Audi Quattro A4 with a 1.8 should replace timing belt and timing belt tensioner at 100,000 miles. It should be checked earlier if your vehicle is subject to severe treatment.
103,000, and I was advised not to drive over that until the timing belt was replaced
by licking it until you drop eggs
120.000
It's not about time. You should change the timing belt every 90k miles.
That requires a timing light, you loosen a bolt on the distributor and turn it a little until the marks on the main pulley match a notch that you aim the timing light at.
When it breaks! You won't know until it breaks but you should inspect it and change it at the recommended interval
