Low coolant with no visible puddle can still indicate a coolant leak. Coolant leaks on German autos may be escaping from the coolant reservoir (expansion tank), a coolant hose, radiator cap, water pump, thermostat housing, heater core, head gasket, or an internal engine coolant leak. Small, slow coolant leaks will eventually evaporate, but will leave a colored residue where the coolant collects. Minor coolant leaks can also create a sweet, chemical smell when the coolant evaporates from the hot engine or exhaust. Small leaks can often be found with black-light leak dye.
The cooling system technicians at Stadium Auto Service can pressure-test the cooling system to find the source of the leak, contact you with an inspection report and a detailed estimate, and perform a quick, same-day repair.
