🚚 Sprinter OM647 Water Pump Installation Instructions

Important:

  • Work on a cool engine to avoid burns.
  • Drain coolant before removing the water pump.
  • Follow all safety procedures and wear protective gear.

🧰 Tools & Supplies Needed:

✅ Socket set & wrenches
✅ Torque wrench
✅ Gasket scraper / razor blade
✅ New water pump (Bosch 98224, Gates 43324, or Mercedes-Benz 6472000101)
✅ New gasket or O-ring (comes with the new pump)
✅ Coolant (compatible with Mercedes-Benz spec, e.g., G48 or HOAT coolant)
✅ Drain pan, funnel, rags

🔧 Step-by-Step Installation:

1️⃣ Preparation

  • Disconnect the negative battery cable.
  • Place a drain pan under the radiator and drain the coolant.
  • Remove the engine cover for access.

2️⃣ Remove the Serpentine Belt

  • Use a wrench on the tensioner to relieve tension and slip the belt off the pulleys.

3️⃣ Remove the Old Water Pump

  • Disconnect the coolant hoses from the water pump.
  • Remove the bolts securing the water pump to the engine block.
  • Carefully remove the pump; some coolant may spill out.
  • Clean the mating surface on the engine block to remove old gasket material or debris.

4️⃣ Install the New Water Pump

  • Place the new gasket or O-ring onto the new water pump.
  • Align the new pump with the mounting holes and install it carefully.
  • Hand-tighten all bolts first to ensure proper alignment.

5️⃣ Torque the Bolts

  • Use a torque wrench to tighten bolts to Mercedes-Benz specifications (typically around 9-10 Nm (80-90 in-lbs), but check the exact torque for your engine).
  • Reconnect the coolant hoses.

6️⃣ Reinstall the Serpentine Belt

  • Route the belt according to the diagram (usually found on the engine bay sticker).
  • Use the wrench to relieve tension on the tensioner and slip the belt back into place.

7️⃣ Refill the Cooling System

  • Reinstall the drain plug on the radiator.
  • Refill the system with fresh coolant using a funnel.
  • Bleed the air from the system by running the engine with the heater on full hot until the thermostat opens and no air bubbles are present.

8️⃣ Check for Leaks

  • Inspect the area around the new water pump and hoses for leaks.
  • Reinstall the engine cover.

🔥 Final Checks:

✅ Recheck coolant level after the engine cools down.
✅ Dispose of old coolant properly—don’t pour it down the drain.
