Emergency Radiator Fan Fuse Replacement Malaysia | MyMechanic
When a cooling fan stops, heat builds fast—especially in slow traffic and tropical weather; cool safely, confirm the fault, replace a blown fuse correctly, and avoid repeat overheating, with MyMechanic providing practical guidance and careful towing across Malaysia.
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.
Find and check the fan fuse (simple, tool‑free steps)
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.
Quick relay sanity check (no dismantling)
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.
Cooling discipline while relocating
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.
