Part Number Lookup:
Precise OEM part numbers for ordering and referencing.
Assembly Disassembly Guidance:
Visual guidance on the order of assembly and disassembly for various components, crucial for correct part fitting.
Component Interchangeability:
Information on component interchangeability where applicable, assisting in sourcing parts from different model years or configurations.
Depth:
Highly detailed, focusing on OEM part identification, illustrations, and correct application. Essential for accurate parts ordering and replacement. Does not typically include detailed repair procedures or diagnostic steps, but is the foundation for them.
Oil Change Interval:
Every 3,000 - 7,500 miles depending on oil type (conventional vs. synthetic) and driving conditions. Consult owner's manual for exact specification.
Tire Rotation Interval:
Every 5,000 - 7,500 miles.
Transmission Fluid Change:
Every 30,000 - 60,000 miles for automatic transmissions (ATF+4 recommended for later models, check for specific spec for '98), manual transmissions may have longer intervals.
Coolant Flush Interval:
Every 30,000 - 100,000 miles depending on coolant type (e.g., HOAT).
Engine Oil Specification:
API SN/SN PLUS or CD, SAE 5W-30 or 10W-30 for gasoline engines; SAE 15W-40 or 5W-40 synthetic for Cummins Turbo Diesel. Consult specific engine manual.
Coolant Specification:
Chrysler/Mopar Antifreeze/Coolant (e.g., HOAT or OAT depending on original fill), typically a 50/50 mix with distilled water. Check for specific color and type.
Transmission Fluid Type:
ATF+3 or ATF+4 for automatic transmissions (check manual for 1998 specifics); GL-5 gear oil for manual transmissions and differentials.
Brake Fluid Type:
DOT 3 or DOT 4.
Common Wear Items:
