Proton X90 Radiator Replacement Malaysia
Radiator maintenance and replacement guide for Proton X90 D-SUV under heavy family load in Malaysia.
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 including new coolant.
If the radiator itself is leaking or severely clogged, replacement is needed. Budget for most Japanese and national cars; for European models. OEM or Denso/Modine quality radiators are strongly recommended over cheap alternatives.
