2004 Pilot timing belt DYI
(for the 105,000 mile timing belt service) Parts List: -Timing belt: 14400-P8A-A02 -Adjuster automatic (hydraulic tensioner): 14520-P8E-A01 -Adjuster - timing belt: 14510-PGE-A01 -Idler pulley - timing belt: 14550-P8A-A01 (OR) 14550-PGE-A01 (there are 2 numbers listed) -Alternator/Compressor belt: 38920-P8F-A02 -Power steering belt: 56992-P8A-A01 -O-RING (8.8X1.9): 91302-GE0-000 -Fender trip clips (X7): 91501-S04-003 Procedure: -Remove tire and place the Pilot on a jack stand. -Remove the clips holding the fender liner and lower splash shield in place (x7) and fold them out of the way. -Make sure the #1 piston is on top dead center using the marks on the crank pulley and lower timing belt cover (19mm in the crank pulley). -Remove the Alternator-Compressor belt (14mm boxend) & Power Steering belt. (2-12mm and 1-12mm tensioner bolt) -Loosen the crank pulley. If you have an impact wrench or a long breaker bar it makes it easier to remove the bolt. You will also need a special tool crankshaft pulley holder (50mm) (19mm and special tool). -Remove the side engine mount bracket (5-14mm bolts). -Remove the crankshaft pulley. -Remove the oil dipstick & tube (10mm). -Remove the front & rear 'upper covers' of the timing belt housing, moving the wire harness out of the way first (5-10mm bolts for each cover). -Remove the lower cover (7-10mm bolts). -Remove the engine mount bracket that is bolted to the block (3-14mm bolts). -Remove the hydraulic tensioner (2-10mm bolts). -Remove the tensioner pulley (you will reuse the inner sleave) (14mm bolt). -Remove the idler pulley bolt (14mm bolt with thread locker on it) (I used Loctite 242 during the reinstall because I had it on the shelf). -Remove the timing belt. -Before installing a new timing belt, make sure the pulleys, belt guide plate, upper & lower covers are clean and check to see if the crank and cams have rotated (mine did not move). -The install is the reverse order of removal (make sure you torque everything correctly!) -The removal of the lock pin in the hydraulic tensioner gave me a little trouble so I used pliers. -Once the crank pulley is back on, check the lower timing mark (and the cam marks) before the top covers are installed. Photos: Looking from above showing the accessory belts removed along with the motor mount.
