Re: Major servicing @ 90000km
what engine? should be stated in the servicing manual.
In general, for most passenger cars close to 100k, should look out for these:
preventive:
1. timing belt kits and water pump, drive belt
2. ignition coils and plugs
corrective (wear n tear - spoil then change. Good to check):
1. chassis suspension (shocks, mounts etc)
2. wishbones, bushes, linkages, steering rods
3. engine mounts
4. brakes - pads and discs. should have been changed once at around 60-80k.
For the ZF 8HP gearbox oil, some say good for life. Others say change at about 100k. Better check with the specialist workshops.
