AISIN Timing Belt Kits with Water Pump

Trust Earned, Reputation Unparalleled

Your service technician will tell you that replacing your timing belt is critical to your engines life. If it fails, severe engine damage can occur. This is also true with the water pump - if it fails, it can also cause severe damage due to overheating.

The good news is that replacing a timing belt is almost bolt-for-bolt the same as replacing a water pump, so it makes sense to replace both at the same time with an Aisin OE Matched Timing Belt Kit with Water Pump for your vehicle.

  • Aisin Timing Kits with Water Pump combine all needed OE matched components into one convenient kit (included components vary by application)
  • Aisin Water Pump with gaskets (select applications include water pump housing)
  • Aisin or NTN OE Hydraulic Tensioner in select applications
  • OE matched Tensioner Spring(s) in select applications
  • OE matched Idler Bearing and Tensioner Bearing (Koyo and NSK brands)
  • OE matched Timing Belt supplied by Mitsuboshi

OE Koyo or NSK Idler/Tensioner Bearings

When performing a timing belt change it's very important to replace the idler and/or tensioner bearings at the same time to ensure longevity of the belt. Koyo and NSK idler bearings are OE installed by many manufacturers and are preferred for their reliability and quality.

    Worth is to get Aisin for sure.
    I initially tried to save a little money, buying the components separately, since I found a Aisin water pump for $30 open box. But after a ton of searching around, I bought this kit.My Water Pump was leaking on my 2005 Tundra 4.7l at 170k miles. At first it was intermittent, but it started getting worse. At one point I hooked up my scan tool, and saw the coolant was 205-210+ degrees during normal driving. Seemed a little high.Ordered this kit, a denso radiator, aisin thermostat, drive belt, tensioner, and went to work.Is definitely a pretty big job. Watched a bunch of YouTube videos, each with a slightly different method, and got to work.I was able to get the fan off without any special tools, just a pry bar and a wrench, but I did but the special tool to hold the crank pulley. I also had to rent a puller to get the crank pulley off. Other than that everything went really smooth.All back together, and now the coolant temp sits right at 186-187 very consistently.Glad I got Aisin parts. Feel much better knowing everything is high quality.Random side note, whoever changed my timing belt last time (previous owner). They installed it backwards, and not using the timing marks! Luckily the timing was correct, and the belt is the same either way, but that was concerning to see that! Glad I have one properly installed now.
