Subaru and VAG Tensioner Tech Tips

New Subaru Timing Belt Tool

When Subaru models with 1.5l, 1.6l, 2.0l, 2.2l & 2.5l petrol engines with manual transmission (e.g. Subaru Forester, Impreza, Liberty, Legacy and Outback) began to show significant timing belt drive systems failure, Gates engineers discovered improper installation was the cause. They went beyond OE and created a special tool that ensures a perfect installation, every time. This tool is part GAT0001 which is now in stocked in Sheffield.

Correct belt clearance is crucial

The affected models are typically fitted with a timing belt guide plate directly above the crank shaft pulley, very close to the timing belt. Manufacturer specifications call for 0.5mm to 1mm (.019” to .059”) of clearance between the belt and guide plate to prevent contact between these components. Belt-to-cover contact causes friction and generates excessive heat, resulting in premature component failure and catastrophic engine damage.

Flawless installation, every time

Needless to say that it’s key to ensure correct clearance across the full arc of the guide plate. Since it’s almost impossible to guarantee this through visual inspection, Gates has developed an application-specific tool to help you achieve the required clearance. When mounting the guide plate, insert the GAT0001 Gates Spacer tool between the belt and the plate. After tightening the bolts, the tool can be removed using the convenient ‘extension tab’, leaving an ideal clearance between the plate and the belt. It’s that simple!

Gates T43219 Tensioner Update

Both Gates and Litens are OE on this VAG tensioner. Gates aftermarket timing belt kits K025649XS and KP25649XS-1 produced before August 4, have the Litens tensioner. Kits produced after that date have the Gates tensioner.

Part T43219 is included in the following fast moving kits:-

K025649XS                   POWERGRIP TIMING BELT KIT

KP25649XS-1                POWERGRIP WPK

Application: VAG 1.2 1.6 2.0 DIESEL

Although both tensioners look visually different (the Gates tensioner has no retaining lug), they are perfectly interchangeable. There is a detailed installation instruction included in the kit boxes, as the Gates tensioner must be rotated counter-clockwise whereas the Litens tensioner must be rotated clockwise.
