Mitsubishi Pajero Sport Radiator Malaysia
Pajero Sport radiator: aluminium core with plastic tanks. Plastic tanks are susceptible to cracking at high mileage (100,000–150,000 km) in Malaysia's heat. Symptoms of radiator leakage: coolant puddle under the vehicle, rising temperature gauge, white steam from the engine bay. The intercooler (separate from the main radiator) should also be inspected — off-road debris can damage fins. Inspect the radiator and its mounting for cracks annually. A cracked radiator that leads to overheating can cause serious head gasket or engine damage.
The radiator keeps your engine coolant at the right temperature by dissipating heat through its fins. In Malaysia's tropical climate — with heavy traffic, high ambient temperatures, and frequent short trips — radiators work harder than almost anywhere else in the world.
Signs your radiator needs attention
- Temperature gauge climbing above normal, especially in slow traffic
- Visible coolant puddle under the car (usually sweet-smelling, green or orange)
- White milky oil — sign coolant is mixing with engine oil (head gasket or cracked block)
- Rust or brown discolouration in the coolant reservoir
Radiator flush vs replacement
A coolant flush every 2 years (or 40,000 km) removes old degraded coolant and inhibitors. This prevents internal corrosion and blockages. Cost: RM 80–150 including new coolant.
If the radiator itself is leaking or severely clogged, replacement is needed. Budget RM 400–900 for most Japanese and national cars; RM 900–2,000 for European models. OEM or Denso/Modine quality radiators are strongly recommended over cheap alternatives.
