Engine and Component Specifications

Precision matters when rebuilding or servicing these classic Jeeps. Torque values are thoroughly documented in multi-stage sequences to ensure proper component seating. Engine oil capacity is specified at 4 quarts for the four-cylinder and V6 units, whereas the 4.0L inline six requires 6 quarts. The cooling system holds 10 quarts for four-cylinder models and 12.5 quarts for the larger V6 and inline six variants.

Transmission fluid requirements strictly call for Mercon ATF for AW-4 units. For the transfer case, the manual dictates SAE 75W-90 GL-5 gear lubricant.
