Parts for your 2006 Mitsubishi Pajero-Radiator

2006 Mitsubishi Pajero Radiator — purpose, care, and replacement

Based on technical sources, a radiator is absolutely fitted to the 2006 Mitsubishi Pajero and is essential to its operation. The Mitsubishi factory workshop manuals for 2006 Pajero models (NM/NP/NS, including 4M41 3.2 Di‑D and 6G75 3.8 V6 engines) describe a liquid-cooled system with a crossflow aluminium radiator and thermostat-regulated flow. Mitsubishi’s electronic parts catalogues and independent service guides (e.g., Haynes/Gregory’s) also list radiator assemblies, caps, hoses, and, on many automatic variants, an integrated transmission fluid cooler. So the radiator is relevant, standard equipment on this vehicle.

The radiator’s job is simple but critical: it sheds heat from the engine coolant so the Pajero holds steady operating temperature under everyday driving, towing, and off-road loads. Coolant circulates through the engine, picks up heat, then passes through the radiator core where air flow—helped by the viscous fan or electric fans—pulls that heat away. Keeping temps stable protects head gaskets, turbos, transmissions (on autos with in‑tank coolers), and extends the life of hoses, seals, and the water pump.

For servicing, owners should run a quality ethylene glycol long‑life coolant that meets Mitsubishi specifications, ideally genuine Mitsubishi Long Life/Super Long Life coolant or an equivalent approved for Japanese vehicles. Avoid mixing coolant colours or chemistries, if switching types, perform a thorough flush with demineralised water. Regularly inspect under the bonnet for staining, crusty residue at hose necks, soft/swollen hoses, or a damp lower tank—early signs of trouble.

• Change coolant at sensible intervals (often 4–5 years or 80,000–100,000 km, or as per the service schedule).
• Check the radiator cap seal and spring, a weak cap can cause boil‑over and air ingress.
• Clean bugs and seeds from the fins, bent fins reduce airflow.
• If the Pajero tows regularly, consider an auxiliary transmission cooler to reduce thermal load on the in‑tank cooler (auto models).

When replacement is due, choose a high‑quality radiator with correct core thickness and fittings. Typical steps include: cool the engine fully, drain and contain old coolant, remove the fan shroud and fan as applicable, disconnect upper/lower hoses and, on autos, cap ATF lines, lift out the radiator, transfer rubbers and mounts, refit and torque correctly, refill with the right coolant mix, bleed air with the heater on, and road‑test, checking for leaks and stable temperature. A sound radiator keeps the 2006 Pajero ready for long hauls and weekend tracks alike.

Popular questions about 2006 Mitsubishi Pajero radiators

What coolant should be used in a 2006 Mitsubishi Pajero radiator?
Owners should use a quality ethylene glycol long‑life coolant that meets Mitsubishi specifications. Genuine Mitsubishi Long Life/Super Long Life coolant or an equivalent Asian‑vehicle approved formula is recommended. Don’t mix different coolant chemistries, if changing types, flush the system and refill with demineralised water and the chosen coolant (or an approved premix).

How often should the radiator and coolant be serviced?
Inspect the cooling system at each service. Coolant is typically renewed every 4–5 years or around 80,000–100,000 km, unless severe duty (heavy towing, dusty off‑road) shortens the interval. Replace the radiator cap and any soft or cracked hoses at the same time to keep the system tight and reliable.

Does the 2006 Pajero radiator include a transmission cooler?
Many automatic 2006 Pajero variants have an integrated ATF cooler in the radiator’s lower tank, manual models do not. If there are two small metal lines at the radiator, it includes the cooler. Frequent towers may add an auxiliary cooler to reduce heat load and protect the transmission.
