Engine Suzuki J24B

The company has been producing the 2.4-liter Suzuki J24B gasoline engine since 2008 and still is. For all the time it was installed only on two models: the Grand Vitara crossover and the Kizashi sedan, therefore there are two versions of the engine of the longitudinal and transverse arrangement under the hood.

Engines of the J-series: J18A, J20A, J20B, J23A, J24B.

In 2008, a 2.4-liter J-engine appeared on the restyled version of the Grand Vitara. This is a common engine for that time with an aluminum cylinder block, cast-iron liners, an open cooling jacket, a 16-valve cylinder head without hydraulic lifters, a timing chain, a variable valve timing system at the intake and distributed fuel injection. Also, this unit is equipped with an intake manifold with an IMT geometry change system.

Disadvantages of the Suzuki J24B engine

  • The first two years of production, defective cylinder blocks simply left the assembly line, cracks in the cooling jacket and antifreeze getting into the lubricant were often encountered. The manufacturer changed the motors under warranty, but you can still find such an engine.
  • The second most popular problem is cracking of the cylinder head due to overheating, you need to carefully monitor the cleanliness of the radiator of the cooling system. On power units of the first years of production, such a problem is especially common.
  • Despite the fact that the leaf timing chain here is designed for the entire life of the engine, in fact it often stretches to 150,000 km, and sometimes much earlier. Usually, along with the circuit, you have to change the phase regulator, which doubles the repair cost.
  • Also, on specialized forums, they regularly complain about the oil burner due to the occurrence of piston rings, very quickly tanning oil seals and valve stem seals, as well as frequent lubricant leaks. It is advisable to check the thermal clearances of the valves and the condition of the candles every 30 thousand km.
