Why is my idler pulley squeaking and leaking coolant
My car has 180000 miles.
My car has an automatic transmission.
It is more likely that something above or behind the idler pulley is leaking coolant and migrating to other areas, like the idler pulley. It can be the water pump, thermostat housing, or seals. The cooling system should be pressure tested by a certified technician, like one from YourMechanic, to find the source of the coolant leak.
