Air Dryers
Air dryers have internal maintenance systems that clean out the accumulated moisture frequently and can therefore work with long maintenance intervals. Eventually the drying medium will be filled up and the cartridge will need to be changed. Change cartridge when there is more water being drained in the daily emptying of the tank than usual. This is a progressive development and the time interval will be different from application to application. Dryer manufacturers recommend changing cartridge every 2 to 3 years but intervals need to be adjusted for application. The only dryer with regular maintenance is the Midland, where the coalescent filter needs changing every year. Note: If a vehicle is operated in a severe weather environment, It is recommended to change the air dryer cartridge prior to the severe weather season.

Steering System
For further information concerning component specifications see service information in Group 1, “Oil and Filter Change Intervals for Volvo Components,” publication number 175-001, and appropriate vendor literature. For axle forward models, grease the steering shaft Ujoints every 4 months. A more frequent maintenance interval may be required if the vehicle is operated under severe driving conditions.
