Engine Power Torque:
Varies significantly by engine. For example, the 5.7L Vortec V8 (L31) typically produced around 255 hp and 330 lb-ft of torque. Consult manual for specific engine ratings.
Fuel Delivery:
Multi-port fuel injection (MPFI) for gasoline engines, indirect injection (IDI) or common rail for diesel engines (depending on specific diesel variant).
Ignition Type:
Distributorless Ignition System (DIS) or traditional distributor ignition depending on engine and specific year updates.
Wheelbase:
Available in various wheelbases: 118.0" (regular cab 6.5' bed), 131.5" (regular cab 8' bed, extended cab 6.5' bed), 168.5" (crew cab 8' bed). Consult manual for exact configurations.
Overall Length:
Varies by wheelbase and cab configuration. Typically ranges from approximately 218" to 260".
Gvwr:
Gross Vehicle Weight Rating (GVWR) varies significantly based on configuration, typically ranging from 7,200 lbs to 10,500 lbs or higher for specific heavy-duty models.
Curb Weight:
Varies by configuration, typically ranging from 4,500 lbs to 6,000 lbs.
Oil Change Interval:
Typically every 3,000-5,000 miles or 3-6 months, depending on driving conditions. Consult the manual for specific recommendations based on engine type and oil viscosity.
Transmission Fluid Change:
Automatic transmission fluid change recommended every 30,000-60,000 miles. Manual transmission fluid change intervals vary. Refer to the manual for precise intervals and fluid types.
Engine Oil Specification:
Refer to manual for specific viscosity grade (e.g., 5W-30, 10W-30) and API service classification. Vortec engines often require SF or SG rated oil.
Coolant Specification:
Ethylene glycol based coolant (green) mixed 50/50 with distilled water. Capacity varies by engine. Specific types like Dex-Cool may be specified for later Vortec engines, but for 1997, traditional green coolant is likely.
Transmission Fluid Type:
Automatic: DEXRON-III (or equivalent). Manual: Refer to manual for specific gear oil grades (e.g., GL-4 or GL-5).
Common Problems:
Potential for intake manifold gasket leaks (Vortec engines), spider injection system issues (early TBI/MPFI), fuel pump failures, exhaust manifold cracks, and HVAC blower motor resistor failures. Diesel models may experience glow plug issues or injector pump problems.
Oil Filter Example:
AC Delco PF2, WIX 51049, Fram PH8A (examples, verify with manual)
Chevrolet Truck Legacy:
Chevrolet has a long and storied history in the pickup truck market, dating back to the early 20th century, known for durability and utility.
C Series Evolution:
The C/K series trucks, including the C3500, underwent significant redesigns. The 1997 model year falls within the third generation (GMT400), introduced in 1988, known for its more aerodynamic styling and improved interior comfort compared to its predecessors.
Manufacturing Plants:
GMT400 trucks were produced at various GM assembly plants in North America, including Fort Wayne, Indiana; Oshawa, Ontario; and Pontiac, Michigan.
