Smile DIY (J35A4) timing belt replacement

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.

Thanks for the writeup. This should have a sticky in the maintenance section! I've bookmarked it for future reference.

One suggestion, modify the parts list so it reads:

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

That is add dashes in the 3rd and 4th items. I know it's a small detail but when I first read the list and saw "adjuster timing belt" and "idler pulley timing belt" it pretty much made no sense and made it seem like there's at least 3 different timing belts for the engine.

My dad's 2004 Pilot need a timing belt. The honda dealer says $750 to replace it and the water pump and new fluids.

I called the toyota service shop where I like to have most of my maintenance done (they work on most models, not just toyota) and they said they could do it but there is a note in there that says it requires a hook up to a computer afterwards so it should probably be done at a Honda Dealer in case it would have to be towed after the procedure.

That step is not included in this writeup so I was wondering if it would be worth it to save probably $300 having the toyota dealer do it.

Any help is appreciated.

thanks.

Better to have one place to blame if it all goes wrong.

I agree but since this is a DIY post and I don't see any computer calibration steps I thougt someone would advise us as to whether is was really necessary. Also it will save about $300+.

thanks.

I don't recall any car being needed to hooked up to the obdii scanner after a timing belt job. Perhaps honda just put that in there to check for codes.

How about you find a shop that specializes in engine work such as timing belts and see what they say.
