AISIN Timing Belt Kit TKF-004 with Water Pump for Saab 9-2X & Subaru 4‑cyl — Complete OE-Matched Service Kit

AISIN TKF-004 is a complete OE-matched timing belt service kit that pairs a premium water pump with a timing belt, tensioner, idler pulleys and gaskets so you can replace the whole system at once.

Replacing the timing belt and water pump together is smart preventative maintenance: the labor overlaps and changing both items at once avoids repeat disassembly later. The AISIN TKF-004 kit bundles components engineered to match original equipment — branded parts from AISIN, Mitsuboshi, Toyo and NTN — and includes everything needed to restore the front-engine timing drive on compatible Saab 9-2X and many Subaru models.

Why should I replace the timing belt and water pump together?

Both parts live behind the same cover and require nearly identical disassembly to access, so replacing them together saves labor cost and reduces the chance of premature failure of the unreplaced item. AISIN’s kit lets you renew the entire system in a single service, which is especially valuable on higher-mileage vehicles.

• Complete kit includes belt, water pump, tensioner, idlers and gaskets
• OE-quality components avoid mismatched wear rates
• Single-service replacement reduces future tear-down and labor
• Carbon-ceramic seals and diecast pump housing for long life

How do AISIN components compare to original equipment?

AISIN manufactures to OE standards and supplies many factory-fit parts, so the TKF-004 kit uses materials and tolerances that mirror the original assembly. That means fitment, pulley alignment and belt tracking match factory expectations, minimizing rework or early issues after installation.

• AISIN water pump with diecast aluminum housing for rigidity
• Carbon ceramic seal technology to resist leakage and wear
• Branded belts and bearings from trusted vendors for consistent life
• Included gaskets and instructions for correct reassembly

Which vehicles does the TKF-004 kit fit and how do I confirm fitment?

The kit was designed for specific Saab and Subaru platforms; engine variations can affect compatibility, so always confirm with your vehicle’s VIN or the seller’s fitment tool before ordering. Typical compatible models include Saab 9-2X (2006) and many Subaru four-cylinder models from the early 2000s to late 2000s.

• Saab: 2006 9-2X (verify engine code)
• Subaru: 2004–2006 Baja, 2004–2007 Forester
• Subaru: 2002–2012 Impreza; 2005–2009 Legacy and Outback
• Check engine and VIN fitment to avoid mismatches

What’s included in the kit and what should a DIY installer expect?

The AISIN TKF-004 kit ships with all primary timing system parts and the water pump so you can complete a full service without sourcing extra components. Installers should have basic timing tools and follow the included instructions or a service manual for torque specs and timing marks.

• Water pump with gasket and seal components
• Timing belt, tensioner assembly and idler pulleys
• Seals, gaskets and hardware as required for reassembly
• Installation instructions included; verify torque and timing procedures

Who is this for: The AISIN TKF-004 kit is targeted at owners and mechanics maintaining Saab 9-2X or Subaru vehicles who prefer OE-quality replacement parts and want the efficiency of a full system service. It’s ideal for vehicles near recommended timing-belt intervals, for high-mileage maintenance, or for anyone wanting to avoid future repeat labor by renewing the water pump and timing components together.
