If you're hearing rattling from your Honda or Acura's 2.4L engine (like the K24Z2, Z3, or Z6), it might be time for a timing chain service. This complete kit has everything you need in one box. It includes a new timing chain, guide rails, tensioners, sprockets (crank and intake), the oil pump chain and its parts, AND a new water pump with a gasket. It's designed as a direct OE replacement, meaning it should fit and function just like the original parts. This kit fits a range of vehicles: 2008-2012 Honda Accord 2.4L, 2010-2011 CR-V 2.4L, and 2009-2014 Acura TSX 2.4L. Be sure to check your specific engine code before buying. Doing both the timing chain and water pump at the same time is smart, as they're in the same area. The kit comes with a 12-month warranty for some peace of mind.
