Vehicle A/C and radiator maintenance requires specialized tools to keep these systems running effectively. Vehicle water pumps circulate coolant between a vehicle's engine and radiator to prevent overheating, and hose adapters assist with replacing water pumps. Vehicle cooling fans keep engines cool and improve fuel economy. Vehicle thermostats regulate the engine's temperature for optimal performance. Radiator caps seal coolant in the radiator and regulate the pressure within the cooling system. Air conditioning clutches transfer the necessary engine power to the air conditioning system.
