Parts for your 1987 Mitsubishi Pajero-Ac condensor

1987 Mitsubishi Pajero AC condenser — fitment, purpose, and service tips

Based on technical sources, the 1987 Mitsubishi Pajero equipped with air conditioning absolutely uses an AC condenser. Mitsubishi’s Factory Service Manual (1983–1991, Group 55 Heating and Air Conditioning) diagrams the condenser as a core component in the system, the Mitsubishi ASA electronic parts catalogue lists a “Condenser, air conditioner” for L040-series Pajero models around 1987, and the Haynes Mitsubishi Pajero 1983–1996 manual describes its location ahead of the radiator. In short, if the vehicle has A/C, it has a condenser.

The AC condenser on a 1987 Pajero is the front-line heat exchanger that turns high-pressure refrigerant vapour from the compressor into a liquid so the cabin can get proper cold air. Sitting in front of the radiator, it dumps heat to the airstream as the vehicle moves, or with help from the A/C condenser fan when idling. On these first‑gen Pajeros, the factory system was R12 originally, and many vehicles have since been converted, the condenser’s job stays the same regardless of refrigerant, though efficiency expectations change.

Owners should keep the fins clean and straight. Road grime, bugs, and mud can mat the fins and kill airflow, which spikes high-side pressures and weakens cooling. A gentle hose from the engine side outward helps, avoid blasting with a pressure washer up close. Bent fins can be teased back with a fin comb. Oily residue on the condenser or at hose unions is a classic sign of a leak, UV dye or an electronic leak detector confirms it. Stone strikes are common on older 4x4s, so a quick look through the grille is worth making part of regular servicing.

If replacement is needed, best practice is to recover the refrigerant, replace the receiver‑drier, renew all O‑rings with the correct material, and flush the lines (where appropriate). For vehicles converted from R12 to R134a, many technicians recommend upgrading to a modern parallel‑flow condenser for better heat rejection in Aussie and Kiwi summers. After installation, the system should be evacuated and recharged by a licensed technician (ARCtick in Australia, and appropriately licensed handlers in New Zealand) to the correct charge mass and oil specification for the compressor used.

Typical symptoms of a tired condenser include weak cooling at highway speeds, the A/C cycling off due to high pressure, or noticeable temperature drop only when the ambient is mild. Ensuring the condenser fan operates and that nothing blocks the grille makes a big difference. With the Pajero’s age, corrosion around the lower tank and brackets is not unusual, if there’s greenish staining or flaking, budget for a replacement sooner rather than later.

• Keep fins clean and straight, avoid harsh washes.
• Inspect for leaks, stone damage, and corrosion.
• Replace receiver‑drier and O‑rings when the system is opened.
• Consider a parallel‑flow unit if running R134a.
• Always have refrigerant work done by a licensed professional.

Popular questions about the 1987 Mitsubishi Pajero AC condenser

Does a 1987 Pajero actually have an AC condenser?
Yes. Factory and dealer‑fit A/C systems on the 1987 Pajero include a condenser mounted in front of the radiator. This is confirmed by Mitsubishi’s Factory Service Manual (Group 55), the Mitsubishi ASA parts catalogue for L040 models, and the Haynes Pajero manual.

Where is the condenser located on the 1987 Pajero?
It sits directly ahead of the radiator, behind the front grille. That position gives it maximum airflow while driving and allows the electric fan to pull air across it at idle or low speeds.

Is upgrading the condenser recommended when converting to R134a?
Often, yes. While the original tube‑and‑fin condenser can work with a proper retrofit, many technicians prefer a parallel‑flow condenser to improve heat rejection and achieve colder vent temps in hot Australian and New Zealand conditions.
