The best way to monitor your oil pump is through watching for the low oil pressure indicator light. This light, located on your dash, comes on if the oil pressure is too low. While this often comes on at the beginning of the issues with the pump, itÆs a clear sign the pump needs fixed. You should immediately make plans to replace it and visit your local AutoZone. AutoZone is providing the right products at the right prices, which includes Grand Marquis oil pumps, so you can rest assured that youÆre scoring the best deals when you shop with us. Shop online with us for Same Day Store Pickup (in most cases) or Free Shipping on purchases of $75 or more.
