Mm I don't think anyone would call a timing belt on a 7y/105k maintenance interval (this is maintenance schedule '4') preventative... more like mandatory? Especially on an interference engine! Also goes with water pump (always recommend replacement not just inspect), and checking your valve clearances.
Main reason is a "CORE" item is because the T-Belt can actually TOTAL your car. Compared to most other "Preventive" maintenance items.Ugh whether or not it’s a core maintenance item, the purpose is ultimately ‘preventative’ if the belt isn’t visibly worn.
Might as well do the other belts and pulley’s while you’re in there (despite it not being a CORE item).
Here is my DIY for Valves: https://www.mdxers.org/threads/diy-adjusting-valves-in-acura-mdx.156393/#post-1365033Awesome. Thank you so much. This is precisely what I was looking for. I have done several timing belts, but I have never checked valve clearance. Can anyone offer any advice or help in that regard?
Yes, you're replacing the belt to prevent damaging the interference engine if the old belt breaks. Recommended change interval is 100k.
It doesn't make any sense NOT to replace Water Pump while you're already there. TB service is labor intensive, time comsuming, 4-5 hrs of labor charge.Do they change it long with the water pump?
Thank you so much, I usually go to my local Mechanic for TB, I am pretty sure they will suggest me to do the water pump too, but not the pulley. Do you know the part number for them?It doesn't make any sense NOT to replace Water Pump while you're already there. TB service is labor intensive, time comsuming, 4-5 hrs of labor charge.
You should also replace Hydraulic Tensioner w/ pulley and idler, no worries for another 100,000 miles!
Just want to be clear, are all these thing in the same area?water pump w/gasket 19200-RDV-J01 (Yamada)
hydraulic tensioner 14520-RCA-A01 (Aisin)
tensioner puley 14510-R9P-A01 (Koyo)
idler pulley 14550-RCA-A01 (Koyo)
You may also consider to replace;
thermostat w/gasket 19315-R9P-A01
Crankshaft Seal - 91212-5MR-A01
Camshaft Seals - 91213-RKG-003 (need 2 of this)
And the Timing Belt 14400-R9P-A01
Above parts are from Acura OE for 2015 MDX, but I would go with Aisin TKH002 TB/WP kit from RockAuto, YMMV
Thermostat is NOT in this area and the seals are just optional(I don't replace these).Just want to be clear, are all these thing in the same area?
Oh MAN, YOU ARE MY SPOTLIGHT! Thank you so much for the advise.Thermostat is NOT in this area and the seals are just optional(I don't replace these).
Also, it's good time to replace the drive belt. Some (myself included) replace belt tensioner and idler, but it's just me. Idler pulley does wear out in 100,000 miles, you should feel engine running quieter after replacing this idler pulley.
Oh, don't forget to get some Honda long life Type 2 coolant.
