Emergency Radiator Fan Fuse Replacement Malaysia MyMechanic

Stabilise and cool first

• Ease off, hazards on, and glide to a straight shoulder or lay‑by; switch off A/C, then the engine.
• Let heat soak drop with the bonnet closed for a few minutes; opening immediately can expose to steam bursts.
• Step out only on the safe side; keep traffic‑side doors closed.

• Locate the engine‑bay fuse box; lift the cover and read the diagram for “cooling fan,” “fan,” or “fan control.”
• Identify the large fan fuse (often high‑amp) and, if present, the smaller fan‑control fuse.
• Pull the suspected fuse straight up; a broken or vaporised link indicates a blown fuse.

Replace correctly

• Insert a spare fuse of the same amperage rating; never upsize to “stop it blowing again.”
• Reseat firmly; check the cover seal to keep moisture and dust out.
• Start the engine and observe: the fan may not spin immediately—watch the gauge and listen for the fan once warm or when A/C is re‑enabled.

• If the new fuse blows quickly or the fan never runs, disable A/C and shut down.
• If a similar relay is in the box (same part number), a brief swap can rule a relay in/out; only swap if it won’t affect critical systems.
• Avoid wire “bridging” or improvised links roadside; it risks harness damage and fire.

Drive or tow: clear decision cues

• Drive gently to a nearby bay if the gauge stays normal, the fan cycles, and no leaks or smells are present.
• Tow now if the new fuse blows, the fan still doesn’t run as temperature rises, the gauge creeps upward, or any smoke/odour appears.
• Night, heavy rain, tunnels, or tight shoulders tilt toward towing.

• Keep speeds moderate; avoid long idle queues; watch the gauge.
• Use cabin heat modestly to shed heat if the gauge creeps; if no improvement, stop and request assistance.
• Do not open a hot radiator cap; wait until cool to touch.

Clues to note for follow‑up

• Immediate re‑blow suggests shorted motor, chafed wiring, or seized fan.
• No fan engagement despite normal fuses hints at sensor/relay/control issues.
• Overheating only at idle/low speed points to fan circuit; at speed points to pump/thermostat/radiator issues.
