DPTOOL Engine Timing Tool Kit for GM 2.0L LSY & 2.7L L3B — Camshaft Locking, Flywheel Locking Tools

This comprehensive kit reproduces the functions of GM service tools (EN-52436, EN-52461 series, EN-52462, EN-52476, EN-52442) so technicians can hold camshaft actuators, lock the flywheel, and remove slack from the timing chain when performing actuator, OCV, or camshaft work on compatible Buick, Cadillac, GMC, and Chevrolet models from 2016–2024. The set is engineered to match the original service tool geometries so you can safely align components, torque fasteners, and prevent phaser rotation during repairs.

How does this kit keep camshaft actuators from rotating during service?

The DPTOOL kit includes EN-52461 camshaft torque reaction tools and adapter inserts that secure the cam phasers in their timed positions. These parts engage keyed surfaces on the phasers so actuators cannot rotate while oil control valves or actuator bolts are removed or tightened.

• Includes EN-52461, EN-52461-100 and EN-52461-200 torque adapters for multiple phaser sizes
• Holds actuators steady for safe OCV removal and camshaft work
• Prevents accidental phaser movement during torqueing operations

What tools are used to lock the flywheel and set crank timing?

The kit supplies the EN-52476 flywheel locking tool which installs where the starter mounts, allowing the flywheel to be positioned and locked. Once installed, the tool’s spring-loaded lock pin engages the timing hole enabling secure torqueing of flywheel and balancer bolts without timing drift.

• EN-52476 replaces the starter for accurate flywheel engagement
• Spring-loaded lock pin indexes into the flywheel timing hole
• Prevents ring gear rotation during bolt installation and torqueing

Can this set remove slack from the timing chain and align camshafts?

Yes — the EN-52436 tensioner retention tool and EN-52462 camshaft alignment tool are included to remove chain slack and keep camshafts in the correct orientation. These tools are used before chain, actuator, or camshaft replacement to ensure components are correctly timed.

• EN-52436 holds timing chain tensioner in service position
• EN-52462 aligns camshafts for precise reassembly
• Works together to eliminate slack before timing work

Which vehicle applications are supported by this DPTOOL timing kit?

The kit is specified for GM engines: 2.0L LSY and 2.7L L3B across many Buick, Cadillac, GMC, and Chevrolet models from roughly 2016–2024. Confirm engine code and model year prior to purchase to ensure compatibility with your vehicle.

• 2.0L LSY: CT5, CT6, XT4, XT5, XT6, Envision, Blazer, Acadia (various years)
• 2.7L L3B: CT4, CT4-V, Colorado, Canyon, Silverado 1500, Sierra 1500 (various years)
• Replaces OEM tools EN-52436, EN-52461 series, EN-52462, EN-52476, EN-52442

Who this is for: Professional mechanics, independent repair shops, and experienced DIYers performing timing chain, cam phaser, or actuator service on GM vehicles with 2.0L LSY or 2.7L L3B engines. If you need OEM-equivalent holding, alignment, and flywheel locking tools to restore correct engine timing and safely torque components, this kit provides the complete set of service tools required for those jobs.
