1. Fan clutch faulty

Thanks for sharing this video. Another system to clean up the rail & pump with injectors is Diesel purge treatment is it ?

[@abcautotrendy]

Well, the best way to use diesal additives at least on every or after 5000KMs

[@sssperera]

@@abcautotrendy Is it okay to use Liqui moly diesel purge ?

[@abcautotrendy]

Yea, that’s the best I’ve found so far.. if not there is another brand call Berner which better an equivalent to LM product

Hello Sir, my Navara d40 (Diesel engine) has been idled for months now. Diagnosed it and it states the problem areas are as follows: 1. Fuel Pump 2. Right-wheel speed sensor & 3. Oil sensor
Also, when turning on AC, it kills the speed even more. What should I do?

[@abcautotrendy]

Hello dear good day.
01. Fuel pump what is the DTC code
02. ABS Sensor (ill send you the part number) but send me the DTC
03. Oil level sensor or oil pressure sensor?
04. If the blower speed continues with his speed it's ned to replace the blower control unit
