How to replace a timing belt on a V6 Honda Accord
The timing belt is part of the engine drive system that connects the crankshaft to the camshaft and controls the timing of the valves of your engine. When the car reaches a high mileage, the timing belt on your Honda Accord can start to wear out and eventually fail.
Mechanics and automakers recommend replacing the timing belt every 90,000 to 100,000 miles for the 2002 V6 engine model.
Also, if you notice that your timing belt is worn, damaged, missing pieces of rubber or broken or shows severe glazing, It must be replaced immediately to avoid costly damage.

1) Disconnect the cable from the negative terminal of the battery. Place the vehicle in the parking lot and apply the parking brake. Lock the rear wheels.
2) Remove the drive belts. Use a wrench in the center of the pulley bolt tensioner and turn the tensioner to the left to release the tension of the belt. Remove the belt.
3) Remove the power steering pump by removing the pump mounting bolts. Move the pump away from the area. Do not disconnect the power supply lines from the pump, place the assembly to one side
4) Remove the spark plugs, to make it easier to turn the crankshaft, by positioning the spark plug box again. And pull it out of the engine by turning the plug counterclockwise.
5) Place the number one piston at the top dead center (PMS), which is the highest point on the cylinder that each piston reaches as it moves up and down during crankshaft rotation. To do this, turn the crankshaft with a socket and the ratchet attached to the threaded bolt on the front of the crankshaft. Rotate until the TDC mark on the crankshaft pulley is aligned with the pointer on the lower cover timing belt.
6) Loosen the front right wheel nuts. Lift the front of the vehicle and rest it securely on cat stands. Remove the right front wheel. Remove the fender splash guards inside the front of the front by removing the bolts that hold the fender interior splash guard in place.
7) Engine mount by placing a floor jack under the oil pan, with a wooden block in the socket to protect the pan. Remove the splash guard from under the radiator by removing the 10 mounting screws from the front of the hood.
8) Remove the two screws and the wiring harness from the retaining harness holding the engine bracket on the passenger side of the block. Remove the bolt tray and remove the bracket. Remove the engine mounting bracket and engine oil dipstick tube.
9) Remove the top timing belt covers from the rear cylinder bank. Mark the belt with the direction of rotation on the timing belt if you intend to re-use the belt. Make sure that the distribution marks are aligned correctly, aligning the markings of the wheel with the mark on the rear cover. Also, check the toothed timing marks on the camshaft that are aligned with the rear drum bench.
10) Use a wrench to hold the crankshaft. Loosen and remove the crankshaft pulley bolt. Remove the lower timing belt cover screws and remove the cover. Slide the timing belt timing belt of the crankshaft, taking into account the installation. Also, note the alignment of the crankshaft pinion adjustment marks.
11) Recheck the position of the distribution marks. Install the timing belt clockwise, starting with the crankshaft sprocket and idler pulley, rear camshaft sprocket, water pump, front camshaft sprocket and idler pulley.
12) Install the outer timing belt guide over the camshaft sprocket with the chamfered edge away from the belt. The beveled edge is the edge that has been machined at an acute angle (less than 90 degrees). Tighten the tensioning pulley bolt to 33 ft-lbs. Remove the battery from the retaining bolt that held the tensioning pulley in place.
13) Rotate the crankshaft slowly six turns clockwise, using a socket and the rod switch on the crankshaft pulley bolt to seat the belt, then return to TDC. Recheck the cam alignment and crank adjustment marks.
14) Install the lower timing belt cover. Install the crankshaft pulley, aligning the key with the crankshaft pulley key (the hole cut to fit the crankshaft key). Position the screw and tighten to 104 in-lbs.
Review the distribution marks again. Reinstall the remaining parts in the reverse order of disassembly.
Reconnect the battery.
