Why does my car scream on cold start?

처리 내용

Most water pumps are designed with a weep hole.This is a small hole that leaks a small amount of antifreeze just before the water pump fails.Most of the time the leak is just above the crankshaft pulley.When you shut off the car the pressure in the cooling system forces some coolant out this hole and it drips onto the pulley and is transfered to the fanbelt.The antifreeze makes the belt slip for the first few minutes.While the car is running the fan blows the coolant away from the belt so you don't notice a puddle or a squeal.
