An oil pump is responsible for circulating the oil throughout an engine. It relies on pressure to do so. If the pressure gets too low, the pump is not doing its job right, which may lead to serious engine damage. You are alerted to low oil pressure by an indicator light on your dashboard. When you see this light, go to AutoZone, where we are providing the right products at the right prices. Find Mountaineer oil pumps online, too, and get Same Day Store Pickup (in most cases) or Free Shipping on purchases of $75 or more.
