Lisle Water Pump Sprocket Holder for GM Ecotec - 13800 Half-Moon Timing Chain Lock, Compact Durable

The Lisle 13800 is a dedicated water pump sprocket holder that locks the timing chain and gear in place while you remove or install the water pump on GM Ecotec engines.

When servicing a water pump on Ecotec four-cylinder engines, holding the timing components steady is critical to avoid misalignment or damage. The Lisle 13800 tool secures the sprocket and chain using the engine's access cover bolts, combining positive retention with a compact profile that clears the pump area. Its half-moon form gives technicians better bolt access and reduces the risk of the chain slipping during pump replacement or installation.

How does this holder prevent timing loss during water pump service?

The tool sandwiches the sprocket and chain so the gear cannot rotate while bolts are removed or torqued. Because it attaches to existing access cover points, it keeps the assembly firmly positioned against the head without improvised fasteners or risk of slippage. This minimizes the chance of re-timing work and the associated extra labor.

• Locks timing chain and sprocket to prevent rotation
• Uses access cover bolts to anchor the tool securely
• Reduces need for secondary alignment checks after pump removal

Will the Lisle 13800 fit all Ecotec engines and where does it mount?

The holder is designed specifically for GM Ecotec family water pump sprockets; verify fit against your engine variant before use. It mounts using the existing access cover fasteners near the water pump area, so no additional modifications are necessary. If your engine has unusual accessories or modifications, check clearance around the half-moon notch.

• Designed for GM Ecotec water pump sprockets
• Mounts using factory access cover bolts for stable positioning
• Half-moon cutout provides bolt access and clearance

What practical advantages does the half-moon design deliver?

The half-moon profile creates an opening that lets you reach the water pump gear bolts without removing the holding tool, so you can work faster and with more control. That shape reduces interference with surrounding components and provides a stable surface against the sprocket's flank. The result is easier bolt removal or installation while the timing components remain secured.

• Half-moon cut allows direct access to pump gear bolts
• Minimizes interference with belt, pulleys, or accessories
• Simplifies one-person pump removal or installation tasks

How compact and durable is the tool for shop use?

Packaged in a slim footprint (approximately 5.75" × 7" × 1.75"), the holder is easy to store on a shelf or in a toolbox and light to position during repairs. It’s built to withstand repeated use during front-end service work and to provide consistent holding force without deforming. The overall design favors durability and repeatability in busy repair environments.

• Compact package dimensions for convenient storage
• Constructed for repeated workshop use and reliable holding
• Simple installation and removal with standard hand tools

Who is this for: The Lisle 13800 is intended for professional mechanics, independent repair shops, and knowledgeable DIY enthusiasts who work on GM Ecotec engines and need a reliable method to prevent timing chain or sprocket movement while servicing the water pump. It’s especially useful when you want a straightforward, repeatable way to protect engine timing without improvisation.
