Dieseldue, thank you for the reply.

Btw, ano na ba ang mileage ng Pajero mo? Your engine needs glow plug assist even when hot if it's mileage is high due to normal wear on the piston rings and liners. High mileage = low compression pressure = low ignition temperature.

Ang mileage ng Pajero ko is 80km. Your compression should still be fine at 80k kms, not unless your engine has experienced overheat condition/s.

I wonder also, I have been replacing glow plugs every six months (starting last year) and mitsubishi parts pa, which cost 1.8k/pc. Mahal talaga ang original Mits glowplugs, but they last long.


do you think something is wrong with the electrical, that's why the glow plugs got busted easily? Possibilities are:
  1. You may be buying fake glow plugs.
  2. Preheat system is defective, voltage is applied to the plugs on an extended duration.
  3. Injection pump may be causing a hard start condition. Prolonged and repeated starts puts a heavy strain on the glow plugs as they are cycled and energized everytime you do a start.
Last, how to check the battery if it needs replacement? kasi kaya pa nitong magstart. Many thanks for your help. Low cranking speed is a good indicator of a weak battery if your starter, bat cables and terminals are in good condition. Motolite etc. can check your battery. You can also do a voltage drop test while cranking.

Do you experience hard start and hesitation during morning starts?
