3F2T-14B192-CA (2-Pack) 12V 40A 4-Pin SPST Automotive Power Relay Compatible with Ford F150 Explorer Expedition Fixes Crank No Start and Fuel Pump Issues Replacement for 15357016 5L3Z-14N089-AA

Restore Reliable Electrical Switching and Circuit Performance to Your VehicleIs your vehicle experiencing sudden stalling, a clicking AC compressor, or a "crank but no start" condition? The 3F2T-14B192-CA (15357016) is a critical electrical switch responsible for managing high-current power flow to your engine management and fuel systems. When aging relays fail due to contact oxidation or thermal fatigue, they cause intermittent power loss. Replacing them with a technical-grade relay ensures a stable connection and prevents roadside breakdowns.Precision Engineering for High-Demand Automotive CircuitsDesigned to handle the intense heat of the engine compartment, this 40-Amp relay maintains a stable current flow even in extreme driving conditions. It features an internal resistor, which is a vital safety component to suppress inductive kickback that could damage sensitive CAN-bus electronics. This multi-purpose relay is a compatible replacement for the 3F2T-14B192-CA series found in various terminal 30 and load reduction applications.Typical Application Scenarios:Fuel Delivery: Compatible with Ford F150 fuel pump relay circuits to fix starting issues.HVAC Control: Restores AC compressor engagement for consistent interior cooling.Engine Management: Provides stable power delivery to the PCM and ignition systems.Safety & Horn: Ensures responsive operation for horn and trailer towing circuits.Installation & Verification:To ensure a precise match, please verify the "3F2T-14B192-CA" or "15357016" stamp on your original relay housing before ordering. This 12V 40A SPST switch is designed for standard automotive sockets; ensure the pins are fully seated to maintain a vibration-resistant connection in your vehicle's power distribution center.

• [ELECTRICAL PARAMETERS] This 3F2T-14B192-CA power relay features a 4-pin SPST design rated for 12V 40A. It includes an integrated resistor for voltage spike suppression, specifically engineered to maintain circuit integrity and protect sensitive engine control modules (PCM/ECM) from electrical feedback
• [EXTENSIVE COMPATIBILITY] Precisely engineered to be compatible with Ford F-150 (2004-2014), Explorer (2002-2010), and Expedition (2003-2017) models. It also fits Lincoln Navigator and Mercury vehicles, providing a secure fit in the power distribution box for reliable electrical distribution
• [DIAGNOSTIC SOLUTION] Effectively addresses common system failures such as "crank but no start" or intermittent stalling. This relay is a direct solution for fixing fault codes like P0230 (Fuel Pump Primary Circuit) and restoring power to AC compressor clutches or radiator cooling fans
• [HEAVY-DUTY BUILD] Constructed with high-conductivity copper coils and silver alloy contact points to prevent internal welding under high-current surges. The rugged housing exceeds standard rigorous testing for high-temperature resistance and vibration stability in engine bay environments
• [MAINTENANCE UTILITY] This set provides two units for essential spare needs in your vehicle's fuse relay center. The standard ISO terminal layout allows for a direct plug-and-play installation to restore power to fuel pumps, horns, and ignition circuits without harness modification
