ACV31212 Automotive Relay 12V 20A 4-Pin SPST (3-Pack), Compatible with Mitsubishi Lancer Outlander Montero Sport, Replacement for MR588567 M07, Fixes Fuel Pump, A/C Clutch & Radiator Fan Issues

Professional-Grade Electrical Restoration for Your VehicleDon't let a $10 component leave you stranded on the shoulder. The ACV31212 / MR588567 relay is a critical "gatekeeper" in your vehicle’s electrical system. When the original relay’s internal contacts wear down or the coil fails due to heat cycles, your fuel pump stays silent or your cooling fans stop spinning.Common Symptoms This Relay Resolves:Hard Starting: Engine turns over but fails to fire (often a failing Fuel Pump relay).A/C Failure: Blower works but the air isn't cold (A/C Compressor Clutch relay).Overheating: Radiator fans fail to kick in during idle or traffic.Intermittent Power: Accessories like horns or fog lights working sporadically.Technical Advantage: Built for LongevityWhile standard aftermarket relays use copper contacts, our ACV31212 replacement utilizes Silver Tin Oxide (AgSnO2) contacts. This material is superior for handling the high "inrush" current of motors and fans, significantly reducing the risk of contact welding and extending the component's service life in high-temperature environments.Pro Installation Advice from the Shop:Safety First: Ensure the ignition is OFF before opening the fuse/relay box.Inspect the Socket: Before plugging in the new unit, check the female terminals for signs of burning or corrosion.Orientation Matters: While the pins are symmetrical, ensure they align perfectly with the socket slots before applying downward pressure.Test the Click: Once installed, have an assistant cycle the ignition or turn on the specific component; a faint "click" from the relay confirms the internal coil is energizing.
