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.

Installation difficulty:Easy — suitable for DIY beginners
