Replacing the heater hose in a 2012 Chevrolet Captiva involves a few essential steps to ensure the vehicle's heating system functions properly. Begin by parking the vehicle on a flat surface, turning off the engine, and allowing it to cool completely. Gather necessary tools, including pliers, a screwdriver, and a new heater hose. Drain the coolant from the radiator by opening the drain valve and catching the fluid in a suitable container for proper disposal or reuse.

Locate the heater hoses, which typically run from the engine to the firewall where they connect to the heater core. Use pliers to remove the clamps securing the old heater hose at both ends. Carefully twist and pull the hose off the fittings. Install the new heater hose by sliding it onto the fittings and securing it with the clamps. Ensure the hose is properly seated to prevent leaks. Refill the cooling system with coolant and start the engine to check for leaks and ensure the heating system works correctly. By following these steps, you can effectively replace the heater hose in Chevrolet Captiva 2012, ensuring optimal performance of the vehicle's heating system.
