How do you change a timing belt on Honda Accord v6?

Answer 1

Wasn't too hard at all. Patience. Just did one couple days ago! Go ahead and raise the passenger side of the vehicle and remove the wheel Assembly's. Support the vehicle with a jack stand appropriately. Next, remove the splash shield that "hides" the crankshaft pulley access area; one 10mm bolt and about 7 plastic clips on right side, no need go all the way across, I didn't. Then i got a small block of wood and placed my jack under the oil pan area, put the wood block between the oil pan and jack, raise it until it touches slightly. Remove the passenger side motor mount. Then you must locate the front motor mount and rear motor mounts and remove the 2 nuts holding each of them down; must do this to raise engine enough to get tensioner idler bolt and engine mount bracket bolt out (rear mount can leave nuts on but back them off till they're about to come off). Remove the serp belt (draw a sketch of how its routed too) and also remove the Power Steering pump and also slip the reservoir to the side. You can also disconnect the clamped line and reinstall after. Just refill after and cleanup.

Thereafter you have removed the engine mount bracket "braces" remove the bolt holding the serpentine belt idler and engine mount bracket in place- you will have to raise the engine approximately 5 inches or so to achieve this. Remove the belt tensioner assembly- has a 12mm bolt from underside of it. Now go ahead and remove the crankshaft bolt, if you don't have a suitable air/impact setup go ahead and put a long breaker bar and socket on the crank pulley bolt and set its reach to the forward of the ground, lower the engine to have the breaker bar touch the ground and turn the key over- that's what I did- works great.

On the timing covers you will see sight hole that you flip open to see the cam gears. put the crank pulley back on if you removed it and rotate the engine clockwise till you see the white marks on the 2 cam gears and the crank pulleys last mark reaches the arrow on the lower timing cover. Remove crank pulley and then upper and lower covers. You now have access to all the cover bolts. Remove them all(10mm). You will then see the idler for the timing belt, loosen it several turns and slip the belt off. Careful make sure your notches/timing marks are inline. There is a hydraulic tensioner on the rear part of belt area-2 bolts hold it on. Remove the belts and tensioner, set tensioner in a bench vise and compress it till the 2 holes match up, slip a hex/ Allen wrench in the hole and release the vise. Reinstall the tensioner, route your timing belt starting from the crank pulley to your front cam pulley then rearwards. be sure to apply most tension while routing belts around cam gears, if the cam gear moves then rotate it back to the correct spot then reroute. Be patient.

Once belt is routed correctly and your 3 timing marks line up pull out the Allen wrench/pin from the tensioner. Install the crank pulley and rotate the engine by hand 2 revolutions. Inspect and make sure the marks are on/real close. If all checks well. then reassembe covers (lower first then put passenger side engine mount bracket on) then upper covers. Put the crank pulley and timing belt guide plate back on. I usually start the engine just like that- all accessories/ serp belt off and run it for a few seconds. Put it in gear too, if it feels different/not normal like rougher idle then your marks may be off too much. If all ok then. Continue in reverse order of removal.-----Wasn't too bad overall.
