The Jeep Comanche, a compact pickup truck based on the XJ Cherokee, holds a special place in the hearts of off-road enthusiasts and classic truck lovers. Produced from 1986 to 1992, the Comanche offered a unique blend of Jeep's rugged capability and truck-like utility. Understanding the nuances of each model year is crucial for anyone considering purchasing or restoring a Comanche.
This guide will delve into the best and worst years of the Jeep Comanche, highlighting the key features, potential problems, and overall value of each model year to help you make an informed decision.
| Model Year | Key Features & Improvements | Potential Issues & Concerns |
|---|---|---|
| 1986 | First year of production, carbureted 2.5L and 2.8L engines, short bed option. | Carbureted engines can be less reliable and harder to maintain than fuel-injected versions. Early models might exhibit more wear and tear due to age. |
| 1987 | Introduction of fuel-injected 2.5L engine, Renix engine management system. | Renix system, while an improvement, can be challenging to diagnose and repair due to its complexity and limited aftermarket support. |
| 1988 | Minor interior updates, improved cooling system. | Renix system issues persist. Potential rust problems, especially in areas with harsh winters. |
| 1989 | More robust axles (Dana 44 available), improved cooling system, standard rear antilock brakes. | Renix system continues. Early signs of rust may be present. |
| 1990 | Introduction of Chrysler's AW4 automatic transmission (replacing the Aisin-Warner), improved interior. | Rust remains a concern. Parts availability may become slightly more challenging. |
| 1991 | High Output 4.0L engine standard, Chrysler's OBD-I diagnostic system, improved interior. | OBD-I system is less comprehensive than OBD-II. Rust is a continuing concern. |
| 1992 | Final year of production, minor trim updates. | Rust is a significant concern. Parts availability can be difficult for specific components. |
Detailed Explanations
1986:
The inaugural year for the Jeep Comanche, 1986 offered a carbureted 2.5-liter AMC engine and a 2.8-liter General Motors V6. The available bed length was a short, six-foot option. While innovative for its time, the carbureted engines are generally considered less reliable and harder to tune compared to later fuel-injected engines, requiring more frequent maintenance and potentially offering poorer fuel economy. Due to their age, 1986 models are more likely to exhibit signs of wear and tear, requiring more extensive restoration work.
1987:
A significant upgrade for the Comanche, 1987 saw the introduction of a fuel-injected 2.5-liter engine, improving reliability and fuel efficiency. It also featured the Renix engine management system. While a step up from carbureted engines, the Renix system is known for its complexity and can be challenging to diagnose and repair, especially due to limited aftermarket support and the need for specialized knowledge.
1988:
The 1988 Comanche received minor interior updates and an improved cooling system, addressing some of the cooling issues present in earlier models. However, the Renix system continued to be used, meaning the potential diagnostic and repair challenges remained. Rust became an increasing concern, especially in regions with harsh winters where road salt was used.
1989:
The 1989 model year brought several notable improvements, including more robust axles (with the Dana 44 available as an option), a further improved cooling system, and standard rear antilock brakes (ABS). The Dana 44 axle is particularly desirable for off-road enthusiasts due to its strength and durability. Despite these upgrades, the Renix system persisted, and the risk of rust continued to grow with age.
1990:
A key turning point, 1990 saw the introduction of Chrysler's AW4 automatic transmission, replacing the Aisin-Warner unit. This transmission is widely regarded as more durable and reliable. The interior also received further improvements. While the Renix system was still present, the improved transmission and interior made the 1990 model a more desirable option. Rust remained a significant concern, however.
1991:
The 1991 Comanche is often considered one of the best years due to the standardization of the High Output (HO) 4.0-liter engine, which offered a significant power increase over previous engines. It also featured Chrysler's OBD-I diagnostic system, a rudimentary but useful tool for identifying engine problems. The interior was further refined. While OBD-I is less comprehensive than OBD-II systems found in later vehicles, it was a welcome addition.
1992:
The final year of production, the 1992 Comanche offered minor trim updates. However, finding parts for specific components can be difficult due to the limited production run and increasing scarcity. Rust is a major concern for 1992 models, and thorough inspection is essential before purchase. Despite being the last year, it doesn't necessarily make it the "best" due to the age and potential maintenance needs.
Frequently Asked Questions
Which Jeep Comanche year is the most reliable?
The 1991 Comanche, with the High Output 4.0L engine and Chrysler's AW4 transmission, is often considered the most reliable due to its improved powertrain and simpler diagnostics compared to earlier Renix-equipped models.
Are Jeep Comanche parts difficult to find?
Yes, parts availability can be challenging, especially for model-specific components and trim pieces; however, many parts are interchangeable with the XJ Cherokee, easing the search somewhat.
What is the best engine for a Jeep Comanche?
The High Output (HO) 4.0-liter inline-six engine, standard in 1991 and 1992 models, is widely regarded as the best engine option for the Comanche due to its increased power and overall reliability.
What should I look for when buying a used Jeep Comanche?
Inspect thoroughly for rust, especially in the floorboards, bed, and rocker panels. Also, check the engine and transmission for any signs of leaks or unusual noises, and test the 4x4 system if equipped.
Is the Jeep Comanche a good off-road vehicle?
Yes, the Jeep Comanche, especially those equipped with the Dana 44 axle and a capable 4x4 system, can be a very capable off-road vehicle, offering a unique blend of Jeep's ruggedness and truck-like utility.
Conclusion
Choosing the best year for a Jeep Comanche depends largely on your priorities. For those seeking the most reliable and powerful option, the 1991 model with the High Output 4.0L engine is generally considered the top choice. However, earlier models, particularly those from 1989 and 1990, offer a good balance of features and affordability. Regardless of the year, thorough inspection for rust and mechanical issues is crucial before making a purchase.
