Step-by-step explanation:
option b is correct When a vehicle's heater core is leaking coolant, the necessary procedure is typically to remove and replace the heater core. The heater core is an essential component of the vehicle's heating system, functioning like a small radiator. It uses the hot coolant from the engine to warm the air that is blown into the cabin. A leak can lead to loss of coolant, decreased heating efficiency, and potential damage to the vehicle's interior.
Options like installing stop leak, rerouting the hoses, or filling the hole with silicone are temporary fixes and may not provide a lasting solution. Stop leak products can sometimes cause clogs in the cooling system. Rerouting the hoses or using silicone may stop the immediate leak but doesn't address the root problem and could lead to further complications down the road. Therefore, a proper repair usually involves removing the faulty heater core and installing a new one.
The necessary procedure when the heater core is leaking coolant is to remove and replace the heater core. The heater core is a component of the vehicle's heating system that is responsible for providing heat in the interior. When it is leaking coolant, it needs to be replaced to ensure proper functioning of the heating system. Other options like installing stop leak, rerouting hoses, or filling the heater core hole with silicone are not recommended as they may not provide a permanent solution and may cause further damage.
