Renault Talisman 1.6 dCi (2019): Coolant Pump (Water Pump) Replacement

On the R9M 1.6 dCi engine, the coolant pump is driven by the accessory drive belt (not by the timing chain; the R9M uses a timing chain). Replacing the pump requires draining the coolant, removing the accessory drive belt, and removing the pump from the engine block. The replacement interval is every 120,000-160,000 km or whenever you notice a leak, bearing play, or unusual noise. It is recommended to combine this job with a coolant change and a new accessory drive belt.

Difficulty: Medium Time: 2-3 hours Steps: 16 Tools: socket set, ratchet, extensions, jack and jack stands, drain pan for coolant (at least 8 L (8.5 qt)), torque wrench, pry bar or special belt tensioner tool

Part

  • 🔩 coolant pump 925164GA0A (equivalents: GRAF PA1185, AISIN), pump gasket, Renault Type D coolant (or equivalent meeting the same specification), accessory drive belt (replacement at the same time is recommended)

Step by step

16 steps
  1. Let the engine cool down completely (at least 2 hours after driving). Disconnect the negative battery terminal.
  2. Raise the front of the vehicle with a jack and support it on jack stands. Remove the engine undertray (if fitted).
  3. Place a drain pan under the radiator. Carefully open the expansion tank cap (to release pressure), then open the radiator drain plug or disconnect the lower hose and drain the coolant completely.
  4. Remove the accessory drive belt: rotate the tensioner counterclockwise (using a special tool or a 15-17 mm socket, depending on the design) and slip the belt off the pulleys. Inspect the belt. If it has cracks, delamination, or worn ribs, replace it with a new one.
  5. Disconnect the hoses from the pump (upper and lower). Be prepared for a small amount of residual coolant to run out.
  6. Remove the bolts securing the pump to the engine block (usually 4-6 bolts around the perimeter). The bolts may have sealant or thread locker on them, so take your time.
  7. Carefully pull the old pump out of its seat. If it is stuck, use a plastic pry tool (not a metal one, so you don't damage the block's mating surface).
  8. Thoroughly clean the mating surface on the engine block of any remnants of the old gasket and sealant. Use a plastic scraper or a clean lint-free rag.
  9. Fit the new gasket onto the new pump (some pumps come with an O-ring instead, so check what is in the kit). If needed, apply a thin layer of cooling-system sealant to the mating surface (only if the pump manufacturer specifies it).
  10. Install the new pump on the block and thread in all the mounting bolts by hand. Tighten the bolts in a crisscross pattern with a torque wrench to 10-15 N·m (7-11 lb-ft) (the exact value is in the manufacturer's specification; if you don't have this data, do not exceed 20 N·m (15 lb-ft), to avoid stripping the threads or distorting the pump housing).
  11. Reconnect the hoses to the pump and tighten the hose clamps (torque 3-5 N·m (2-4 lb-ft), or hand-tight without excessive force).
  12. Install the new belt (or the old one, if it is in good condition) onto all the pulleys and tension it using the tensioner. Check the tension: the belt should deflect 5-10 mm when pressed with a finger at the longest span.
  13. Close the radiator drain plug (or reconnect the lower hose). Pour fresh coolant into the expansion tank up to the MAX mark.
  14. Reconnect the negative battery terminal. Start the engine and let it idle for 5-10 minutes. Watch the coolant level in the tank. It will drop as the system bleeds, so top it off.
  15. Warm the engine up to operating temperature (the cooling fan will switch on). Check for leaks at the pump connections and hoses.
  16. Shut off the engine and let it cool for 15-20 minutes, then check the coolant level again and top off to MAX if necessary. Install the engine undertray.

Common mistakes and warnings

  • The R9M engine has a timing chain drive. Do not confuse it with the coolant pump, which is driven by the separate accessory drive belt. Do not use an incompatible type of coolant (only Type D or equivalents meeting the Renault specification), as this can cause corrosion of aluminum parts. If you notice a leak or pump noise, do not put off the replacement. A failed bearing or impeller will lead to engine overheating and expensive repairs. If you have no experience working on cooling systems, have the replacement done by a professional.
