Step-by-Step Instructions

Follow these steps carefully

1

Prepare (TTY bolts, EN-46104!)

3.6L V6 (LY7): pump mounts on the FRONT (timing) cover — accessory-style, NOT timing-chain-driven like the 2.4L. EN-46104 pulley holder required. TTY: NEW bolts, 10 N·m (89 lb-in) two passes + final 45°; pulley bolts 10 N·m. New pump, NEW seal, Dex-Cool.

2

Drain, Access the Front Cover

Let the engine cool and drain the Dex-Cool. The pump sits on the FRONT (timing) cover — accessory mounting, not timing-chain-driven like the 2.4L. Clear obstructing components for access. The EN-46104 holder is required to hold the pulley — don't attempt this without it.

3

Remove Pump (discard TTY bolts!)

Hold the pulley with the EN-46104 holder and remove its bolts (10 N·m on reinstall). Remove the pump bolts — they're torque-to-yield: discard, do NOT reuse. Remove the pump and DISCARD the old seal. Clean the front-cover mating surface.

4

Install New Pump (TTY: 10 N·m + 45°!)

Install the new pump with a NEW seal and NEW TTY bolts: 10 N·m (89 lb-in) in two passes plus a final 45° — don't skip the angle. Pulley bolts: 10 N·m with the EN-46104 holder. Reused bolts won't hold clamping force.

🔧 Mechanic's note — Ray Delgado

Torque-to-yield means one use, period. I've seen reused TTY bolts back out and dump coolant on the highway. New bolts, two passes at 10 N·m, then the 45-degree turn — every time.

5

Refill Dex-Cool, Bleed

Refill with Dex-Cool — not green, not Asian. Fill the surge tank. Bleed: run to operating temp with heat on max, cool, recheck. The 3.6L bleeds normally. Verify the new seal isn't leaking — the front-cover location makes a leak visible.

6

Verify, Check Seal, Recheck

Start the engine and check for leaks at the pump and new seal; the gauge should climb to normal. The 3.6L's recipe: front-cover accessory mounting (not timing-chain like the 2.4L), NEW TTY bolts (10 N·m two passes + 45°), EN-46104 holder, new seal, Dex-Cool.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Not properly draining the coolant before starting the repair
  • • Failing to replace the gasket or O-ring with the new water pump
  • • Over-tightening bolts, leading to gasket damage or warping
