Renault / Nissan K9K 1.5 dCI

Renault / Nissan K9K The Renault K9K 1.5 dCI is a 1.5 l (1,461 cc, 89.15 cu-in) straight-four 4-stroke turbocharged diesel engine co-developed by Nissan and Renault. The engine is produced since 2001. The K9K engines are available in different versions, each configuration corresponds to the three-digit code and have deifferent specificatons.

The K9K engine features cast-iron block with five-bearings crankshaft and aluminum head with a single camshaft (SOHC) and two valves per cylinder. The K9K 1.5 dCI has a common-rail injection system and turbocharger Borg-Warner.

There are three versions of 1.5 dCI engine: a low power level version, a high power level version and a high power version with variable geometry turbocharger. Low power versions (up to 66 kW) uses the Delphi fuel injection system for Euro 3,4 engines or Bosch for Euro 5 versions. High power versions (70 kW and higher) uses fuel injection system by Continental. The engines are equipped with EGR-system and latest modifications use diesel particulate filter.

A 76.0 mm (2.99 in) cylinder bore and 80.5 mm (3.17 in) piston stroke give the motor a total of 1,461 cc of displacement. Compression ratio rating is 15.2:1.

It produces from 65 PS (48 KW; 64 HP) to 110 PS (81 KW; 108.6 HP) of horsepower and from 160 Nm (16.3 kg·m; 118.1 ft·lb) to 260 Nm (26.5 kg·m; 191.9 ft·lb) of torque.

    • For K9K on Nissan Qashqai J11
      Main bearing cap bolts:
      Step 1: 25 Nm; 2.6 kg·m; 18 ft·lb
      Step 2: Turn all bolts 47 degrees clockwise

      Connecting rod bearing bolts
      Step 1: 20 Nm; 2.0 kg·m; 15 ft·lb
      Step 2: Turn all bolts 45 degrees clockwise

  1. How can I find out which way round the conrod should face in the block? The engine was stripped and the tech didn’t take note of the orientation.

  2. I got Dacia Logan MCV 2008 and engine is K9K 8796,,you showing only Sendero is come with this engine.
