How Often Should Car Drain Holes Be Cleaned?

[MollyMarie]

Drain holes for components such as sunroofs, engine compartments, and air conditioning systems must be regularly cleaned before the rainy season arrives. Below is relevant information: 1. Air Conditioning Drain Hole: The air conditioning drain hole is typically located at the bottom of the evaporator box and connected to the chassis via a hose. Its function is to discharge the condensation water formed during the heat exchange process when the air conditioning is in use. This is also why a puddle of water appears under the car after the air conditioning has been running for a while. 2. Engine Compartment Drain Hole: The engine compartment drain holes are generally located on both sides of the front windshield wipers, usually one on each side. Since the engine compartment is a relatively open environment, sewage, fallen leaves, and other debris can flow into the engine compartment along the windshield. Engineers have designed a water barrier at the rear of the engine compartment, along the lower edge of the windshield, and incorporated drain holes in the barrier's location.
