1998 Mitsubishi Pajero Radiator — Purpose and Servicing Advice

Yes, a radiator is absolutely fitted and relevant to the 1998 Mitsubishi Pajero. Technical references, including the Mitsubishi Pajero factory workshop manual (late-1990s V20 series), the Mitsubishi ASA electronic parts catalogue, and common aftermarket guides (e.g., Haynes/Max Ellery), all specify a liquid-cooled system with a cross-flow aluminium radiator and plastic end tanks. Petrol V6 and 2.8L turbo-diesel variants both rely on this radiator to manage engine heat, and most automatic models integrate a small transmission fluid cooler in the radiator’s tank.

The radiator’s job is simple but critical: it sheds the heat picked up by the coolant as it circulates through the engine. Working alongside the thermostat, water pump, fan clutch/electric fans, and the radiator cap, it helps keep operating temps stable for performance, longevity, and reliability—especially important for Kiwi and Aussie conditions, whether towing the boat or crawling a fire trail.

For servicing, sticking to quality coolant (ethylene glycol, mixed 50/50 with demineralised water unless otherwise specified) and changing it on time makes a huge difference. Many workshops recommend flushing every 2–4 years or 40,000–60,000 km. When the radiator’s out for repair or replacement, it’s smart to renew upper and lower hoses, hose clamps, and the thermostat. If it’s an auto, treat the in-tank trans cooler with care—cap the lines while the radiator’s out, then check and top up ATF afterwards.

Common warning signs that a Pajero radiator needs attention include persistent overheating, coolant stains or sweet smells around the front end, brown or sludgy coolant, a cracked plastic tank, a weak radiator cap, or cooling fans that don’t cut in properly. Off-roaders should also watch for mud and seeds clogging the fins—restricted airflow can spike temps even if the coolant’s fresh.

• Flush with the heater on, refill slowly, and bleed air by gently squeezing the top hose and letting the engine warm up nose-up on ramps.
• Use a cap and coolant that meet OEM specs
