VIN Code ID Explanation. Scheme 3
SEVERE & NORMAL SERVICE DEFINITIONS
Note. Use the Severe Service schedule if the vehicle to be serviced is operated under ANY (one or more) of these conditions
Service is recommended at mileage intervals based on vehicle operation. Service schedules are based on the following primary operating conditions
Normal Service
- Driven More Than 10 Miles Daily
- No Operating Conditions From Severe Service Schedule
Severe Service (Unique Driving Conditions)
- Extended Idling Or Low Speed Operation
- Frequent Short Trips Of Less Than 7 Miles
- Extended Operation In Dusty Or Sandy Conditions
- Trailer Towing Operations
- Driving In Mountainous Conditions
CAMSHAFT TIMING BELT
| CAUTION | Failure to replace a faulty camshaft timing belt may result in serious engine damage. |
The condition of camshaft drive belts should always be checked on vehicles which have more than 50,000 miles. Although some manufacturers do not recommend belt replacement at a specified mileage, others require it at 60,000-100,000 miles. A camshaft drive belt failure may cause extensive damage to internal engine components on most engines, although some designs do not allow piston-to-valve contact. These designs are often called "Free Wheeling".
Many manufacturers changed their maintenance and warranty schedules in the mid-1980's to reflect timing belt inspection and/or replacement at 50,000-60,000 miles. Most service interval schedules in this manual reflect these changes.
Belts or components should be inspected and replaced if any of the following conditions exist
- Cracks Or Tears In Belt Surface
- Missing, Damaged, Cracked Or Rounded Teeth
- Oil Contamination
- Damaged Or Faulty Tensioners
- Incorrect Tension Adjustment
Volvo recommends replacement of the camshaft timing belt at the following intervals
| Application | Interval (Miles) |
|---|---|
| 1993 | 50,000 |
| 1994-96 | 70,000 |

| CAUTION | Lubrication of the Tensioner Pulley Bushing is REQUIRED on 1993 Models, it is recommended that the bushing be checked for free play and lubrication on 1994-95 models. |
Note. For more information regarding camshaft timing belt service refer to the 2.3L 5-CYL TURBO article in the ENGINE MECHANICAL section.

Note. The automatic tensioner for the auxiliary drive belt must be greased every 30,000 miles (45,000 km) or if an abnormal noise is heard from the tensioner.
Note. The auxiliary drive belt and automatic tensioner must be removed from engine in order to properly lubricate.

| CAUTION | Use extreme caution when putting a T-5R model, or any model with a front spoiler and lowered suspension onto a lift. |
Note. For more information regarding lifting and hoisting refer to the JACKING & HOISTING article in the WHEEL ALIGNMENT section.

SERVICE LABOR TIMES
Note. Labor times are provided, where available, within appropriate SERVICE INTERVAL table in SCHEDULED SERVICES article.
TIRE INFLATION
Tire specification label is located on the right front door.
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR BAG SYSTEM
Note. See the AIR BAG RESTRAINT SYSTEM article in the ACCESSORIES/SAFETY EQUIPMENT Section.
The SRS has no user-servicable parts. Always have servicing done by an authorized dealer.
When performing maintenance on air bag equipped vehicles always observe proper safety precautions.
| WARNING | To avoid injury from accidental air bag deployment, read and carefully follow all warnings and service precautions. See appropriate AIR BAG RESTRAINT SYSTEM article in the ACCESSORIES/SAFETY EQUIPMENT section. |
| CAUTION | Disconnect negative battery cable before servicing any air bag system, steering column or passenger side dash component. After any repair, turn ignition key to the ON position from passenger's side of vehicle in case of accidental air bag inflation |
ANTI-LOCK BRAKE SYSTEM (ABS)
| CAUTION | Never mix different diameter tires. On loose or uneven surfaces, the ABS system may require longer stopping distances than conventional brake systems. Exercise caution when removing mud or snow from the wheels so as not to damage the ABS wiring or speed sensors. |
BATTERY WARNING
| WARNING | When battery is disconnected, vehicles equipped with computers may lose memory data. When battery power is restored, driveability problems may exist on some vehicles. These vehicles may require a relearn procedure. See appropriate COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section below. |
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off all lights and accessories to avoid damaging the electrical system. Be sure to use fuse with the correct indicated amperage rating. The use of an incorrect amperage rating fuse may result in a dangerous electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning that brake pads need replacement.
CATALYTIC CONVERTER
Continued operation of vehicle with a severe malfunction could cause converter to overheat, resulting in possible damage to converter and vehicle.
COOLANT (PROPYLENE-GLYCOL FORMULATIONS)
| CAUTION | To avoid possible damage to vehicle use only ethylene-glycol based coolants with a mixture ratio from 44-68% anti-freeze. DO NOT use 100% anti-freeze as it will cause the formation of cooling system deposits. This results in coolant temperatures of over 300° F (149°C) which can melt plastics. 100% anti-freeze has a freeze point of only -8° F (-22°C). |
| CAUTION | Propylene-Glycol Mixtures has a smaller temperature range than Ethylene-Glycol. The temperature range (freeze-boil) of a 50/50 Anti-Freeze/Water Mix is as follows: Propylene-Glycol -26° F (-32°C) - 257° F (125°C); Ethylene-Glycol -35° F (-37°C) - 263° F (128°C). |
| CAUTION | Propylene-Glycol/Ethylene-Glycol Mixtures can cause the destabilization of various corrosion inhibitors. Also Propylene-Glycol/Ethylene-Glycol has a different specific gravity than Ethylene-Glycol coolant, which will result in inaccurate freeze point calculations. |
ELECTROSTATIC DISCHARGE SENSITIVE (ESD) PARTS
| WARNING | Many solid state electrical components can be damaged by static electricity (ESD). Some will display a warning label, but many will not. Discharge personal static electricity by touching a metal ground point on the vehicle prior to servicing any ESD sensitive component. |
ENGINE OIL
| CAUTION | Never use non-detergent or straight mineral oil. |
FUEL SYSTEM SERVICE
| WARNING | Relieve fuel system pressure prior to servicing any fuel system component (fuel injection models). |
HALOGEN BULBS
| WARNING | Halogen bulbs contain pressurized gas which may explode if overheated. DO NOT touch glass portion of bulb with bare hands. Eye protection should be worn when handling or working around halogen bulbs. |
RADIATOR CAP
| CAUTION | Always disconnect the fan motor when working near the radiator fan. The fan is temperature controlled and could start at any time even when the ignition key is in the OFF position. DO NOT loosen or remove radiator cap when cooling system is hot. |
RADIATOR FAN
| WARNING | Keep hands away from radiator fan. Fan is controlled by a thermostatic switch which may come on or run for up to 15 minutes even after engine is turned off. |
TURBOCHARGED MODELS
| CAUTION | Do not race engine immediately after starting. When stopping engine, allow engine to idle for approximately 60 seconds before shutting it off. Failure to do so may cause turbocharger damage due to lack of oil flowing to the turbocharger bearings. |
WHEELS & TIRES
Only wheels tested and approved by the manufacturer should be used on models equipped with Air Dam aerodynamic components.
