Renault Kadjar 1.5 dCi 110 (2020): Timing Belt Replacement with Rollers and Water Pump

On the 1.5 dCi (K9K), the timing belt drives the camshaft and usually the water pump. A broken belt causes the valves to hit the pistons and leads to expensive engine repairs. Renault's replacement interval depends on operating conditions and model year. For taxi use, city driving and frequent short trips, replace it earlier, at roughly 90,000-120,000 km or every 5 years. Check the exact interval in your service booklet.

Difficulty: Hard Time: 4-6 hours Steps: 16 Tools: Socket and wrench set, torque wrench, timing tool set for K9K engines (crankshaft locking pin, camshaft locking pin or plate, high-pressure pump pulley lock if required), jack or lift, safety support or engine support stand, flywheel/pulley holding tool, marker, coolant for topping off

Part

  • 🔩 Timing belt kit for 1.5 dCi (K9K): timing belt, tensioner pulley, idler pulley, pulley and roller bolts. It is best to replace the water pump at the same time, with a gasket or O-ring, if it is driven by the belt. Brands: Gates, Contitech, SKF, INA, Dayco

Step by step

16 steps
  1. Park the car on a level surface and disconnect the negative battery terminal. The engine must be cold. Raise the car and remove the right front wheel and the fender liner. Remove the engine undercover.
  2. Remove the engine cover and the air intake hoses that block access to the right engine mount. Drain the coolant if you are replacing the water pump.
  3. Remove the accessory drive belt. Note the tensioner position or photograph the belt routing.
  4. Support the engine from below with a jack, using a wooden block under the oil pan. Remove the right engine mount with its bracket. This is needed to access the upper timing cover.
  5. Remove the upper plastic timing belt cover. The lower part of the cover can be removed after taking off the crankshaft pulley.
  6. Turn the crankshaft in the normal direction of rotation by the pulley bolt to top dead center (TDC) of cylinder 1. Insert the crankshaft locking pin into the timing hole in the block, and the pin or plate onto the camshaft. The marks must line up without any offset.
  7. Remove the crankshaft pulley. The pulley bolt is very tight, so use a pulley holding tool. Do not turn the engine by the camshaft bolt.
  8. Use a marker to draw direction-of-rotation arrows on the old belt. Loosen the tensioner pulley and remove the belt. If you are replacing the water pump, remove it and clean the mounting surface.
  9. Inspect the pulleys and the camshaft and crankshaft seals. If there are signs of oil, replace the seals, otherwise the new belt will fail quickly.
  10. Install the new water pump with a new seal, then the new pulleys. Tighten the bolts to specification. For the pulley and pump this is usually 20-30 N·m (15-22 lb-ft), but take the exact values for your engine from the manufacturer's manual.
  11. Install the new belt. Installation order: crankshaft pulley, idler pulley, camshaft pulley, water pump, then the tensioner pulley. The section between the crankshaft and camshaft, in the direction of rotation, must be taut. Match the marks on the belt to the marks on the pulleys.
  12. Tension the belt using the tensioner mark or a tension gauge, then tighten the pulley. On K9K belts it is important to set the tension exactly: a loose belt skips teeth, while an overtightened one whines and quickly wears out the water pump.
  13. Install the crankshaft pulley and tighten a new bolt. On the K9K the bolt is usually tightened in two stages: first to a torque, then by an angle. Take the exact N·m and degree values from the service manual. Never reuse the old bolt.
  14. Remove the locking pins. Turn the crankshaft by hand 2 full turns in the normal direction of rotation and make sure the marks line up again and the pins go in freely. If they do not, the belt has shifted and the engine must not be started. Disassemble and repeat.
  15. Reassemble in reverse order: the timing belt covers, engine mount, accessory drive belt, hoses, engine undercover and wheel. Top off with coolant of the correct specification and bleed the air from the cooling system.
  16. Start the engine, let it warm up, and check the coolant level and look for leaks. Check the level again after a few days. If an error code for the crankshaft or camshaft sensors remains on the dashboard, read and clear it with a diagnostic scanner.

Common mistakes and warnings

  • This is a difficult job: do not attempt it without locking pins and an understanding of the timing marks. An error of even one tooth causes the valves to hit the pistons. If you lack experience, it is better to have a repair shop do the work. Do not keep the old water pump and pulleys: they cost less than a second teardown. After the replacement, write down the mileage and date in the service booklet.
