Maintenance of CRDi system vehicle starts from fuel filter replacement. | |
Advanced technology of CRDi based diesel vehicles allows higher power and improved fuel efficiency than conventional diesel system.

WATER SENSOR
|
|
If more than a certain amount of water accumulates on the bottom of the water filter, you can see the water separation warning light to exchange water filter. If you drive continuously not to respect the warning light, water will penetrate into fuel system and it affects CRDi engine adversely. So the Common Rail engine has a water filter (water sensor) that separates water contained in the fuel and stores water separately from the fuel in the tank. |
|
INJECTOR | |
Oil film on the CRDi injector or the high-pressure pump prevents from friction and noise between metals. Non moisture filtered fuel deteriorates oil film and worsens fuel system. It is the main cause of malfunction of the fuel supply system and may cause wear and tear of parts. |
|
TEMPERATURE SENSOR | HEATER |
A paraffinic (CnH2n + 2) ingredient in fuel tends to solidify at zero degree Centigrade. Fuel filter to have heating device helps a lot to melt this paraffinic ingredient in the winter time. |

FILTER OVER THE EXCHANGE INTERVAL
|
|
AFTER EXCHANGE | BEFORE EXCHANGE |
It is not exaggeration to say that the first step to care diesel vehicle is fuel filter replacement. |

- Every 30,000 km (typical)
