Engine Renault K9K

The 1.5-liter Renault K9K or 1.5 dCi diesel engine has been produced by the concern since 2001 and is installed on a huge number of company models under the Renault, Nissan or Dacia brands. The same motor can be found under the hood of front-wheel drive Mercedes called OM607 and OM608.

The K-series include: K4J, K7J, K4M, K7M and K9K.

In 2001, a 1.5-liter diesel debuted on the second generation of the popular Clio model. It was quite a typical engine for its time with a Common Rail fuel system, a 4-cylinder cast-iron block, an aluminum 8-valve head without hydraulic lifters, a timing belt drive, a KKK or BorgWarner turbine and, of course, an intercooler.

Fuel systems from three manufacturers were installed on these engines: until 2009, Delphi was installed on all versions of units up to 100 hp, and Siemens was installed on powerful ones, then in 2009 Delphi replaced Bosch, and Siemens remained, but was renamed Continental. Low-power versions of this unit were equipped with a conventional BorgWarner KP35 turbocharger, and engine modifications over 100 hp with a BorgWarner BV39 variable geometry turbine. There are four generations of such engines under Euro 3, 4, 5 and 6 environmental standards, respectively.

Disadvantages of the Renault K9K engine

  • The most famous problem with such engines is cranking of the connecting rod bearings. This happens especially often with engines from Europe, where they change the oil every 30,000 km.
  • The bulk of diesel engines until 2009 were equipped with the Common Rail Delphi system, which does not tolerate airing, a clogged fuel filter and bad diesel fuel. For any of these reasons, it begins to drive chips and primarily clogs the nozzles. Also, this metal pollen significantly reduces the life of the turbine and oil pump.
  • The fuel system manufactured by Siemens or Continental is much more reliable, but its repair costs more money, some piezo injectors are several times more expensive. Therefore, we do not have an unambiguous opinion about which company’s equipment is better.
  • Most diesel cars from Europe are equipped with a particulate filter and an EGR valve, which tend to clog.
  • Much less often, such motors fail due to a drop in lubricant pressure in the system. This is due to the oil filter valve and the oil pump pressure reducing valve spring.
