Buying advice

When choosing a radiator fan relay, prioritize OEM or reputable brands for reliability. Check the amperage rating to match your fan's draw, and ensure the connector type fits your vehicle. For longevity, look for sealed or waterproof relays. Price is usually not indicative of quality, but very cheap units may fail quickly.
