🔧 Passport - Water Pump Replacement

On your Passport, the water pump is driven by the timing belt, so replacing the pump requires removing the timing belt and related covers. Because of that, most people replace the timing belt components at the same time to avoid doing this labor twice.

Difficulty Level: Advanced | Estimated Time: 5-8 hours

⚠️ Safety & Precautions

• ⚠️ Let the engine cool completely before opening the cooling system.
• ⚠️ Support the engine before removing the right-side engine mount.
• ⚠️ Never rotate the engine with the timing belt removed unless instructed.
• ⚠️ Keep hands/tools clear when releasing timing belt tension.
• ⚠️ Battery disconnect is recommended before working near the starter/alternator wiring.

🔨 Step-by-Step Instructions

Follow these steps in order:

Before I give you the exact torque-spec’d steps:

• Are we talking about your Passport?
• Do you want the procedure for water pump only or the recommended water pump + full timing belt kit (belt, tensioner, idlers)?

Why I’m asking:

• The water pump is behind the timing belt covers, so “pump only” still requires nearly the same teardown as doing the full kit.
• I’ll tailor the steps and parts list to match your choice and keep you from redoing labor.

✅ After Repair

• Verify there are no coolant leaks at the pump, hoses, and drain points.
• Confirm normal operating temperature and stable cabin heat.
• Recheck coolant level after the first full heat-soak/cool-down cycle.
