Does 2004 toyota avalon engine needs timimg belts change?

You have a timimg belt.

this is for 2004 don't know if same engine.

you did not especify engine type, if you only remove the distribuitor, or you are changing timimg belt(broken belt V6 only)

Typically any timing belt replacement interval is 60k-75k miles. The book will however tell you 90k. Now it depends on what engine your Avalon came with. The 3.0 is a non interference engine meaning if it does snap, it will not cause any damage to your engine. The 3.5L engine however i dont know if its a interference engine or not but i dont see anywhere where it says it is. As always suggested, change your water pump as well, as it runs off the timing belt. Once i didnt change the water pump and a week later it locked up on me and ruined my perfect new timing belt. Truth be told :) lol

2002 Toyota Avalon Belt Routing




Hope helps.

Big job to do......You begin by draining the coolant into a container, removing right-front tire, crank-pulley straight up, taking-out the belt-cover...etc....why not get the popular Hanyes repair manual sold for under $20/copy? Timing-belt, alternator, a/c it explains it all. Or better still, avoid possible engine damage, take to shop.

the thermostat is on the engine end of the lower rad hose the water pump is under the timing belt cover it is usually changed with the belt

The first thing to do is try another key. Perhaps your transponder key has failed.
You can identify a 'transponder key'; it has a wide part wher you turn it.

There is no real way of telling as there are cords buried in the rubber of the belt that break.Toyota says to replace it every 90,000 mi..I have seen them last longer but that would be your call.If you get it done you should also change the drive belts as they have to take them off and on anyway and you should only have to pay the parts.That is if they are original.Thanks for using fixya
