1. Replaced spark plugs with NGK platnium ones, how often should i replace these? after how many K's? i was told they can last for 60,000k's Should i be checking the condition every so often or?? well they should last you about 60k but check em every 10,000kays
2. The fan onfront of the raidator is never working, how do i go about troubleshooting this? would it be a simple fuse? My temp guage sits at around 50 - 55%. dont worry about it. theres a thread wat cubes made about wiring it up wen u put ur air con on. so the car doesnt heat up as much.
3. Gearbox and Diff oil, how often does this need to be changed?
i say about every 10,000 kays
4. Fuel Filter i replaced, but how often should this be replaced?
once a year
5. Lastly, when goto start the engine, i get this crunch / grind sound
ur starter motor might be on its way out or ur holding the key on start to long
cheers
