Relay buying guide
Why replace this part?
Relays are electrically-operated switches that control high-current circuits (fuel pump, fan, starter, horn) from a low-current trigger. A failed relay can disable critical systems without visible damage and is often overlooked during diagnostics.
Signs you need a replacement
- Component controlled by the relay fails to operate
- intermittent operation
- clicking from the relay box but no function
- relay runs hot or smells burnt
When to replace
No fixed interval — replace on failure. Always carry spare relays for critical circuits such as the fuel pump relay and fan relay.
