1990 Jeep Comanche Service and Repair Manual
Regular price
$29.99 USD
Unit price
The 1990 Jeep Comanche factory service and repair manual is matched to this exact model year, so the procedures and specifications are correct for both of its engines and all three trims.
Engines

- 4.0L I6 — 242 cu in, OHV
Trims
- Base Standard Cab Pickup

Known issues on the 1990 Comanche. Two recalls are on federal record for this model year: a disc brake rotor whose cast iron wear surface can separate from the hub and reduce braking, and a cruise control fault where high engine idle when the vehicle is first placed in gear can cause unexpected acceleration. There are 15 owner complaints on record, and Jeep has issued 10 technical service bulletins for the year.
From a routine service interval to a brake overhaul or a hard-to-trace electrical fault, it keeps you on the correct factory procedure and specification for your specific 1990 Comanche.
