In order to pass a smog test, the EGR valve for your Mercury Grand Marquis needs to be properly maintained. Over time, a failing EGR valve gets backed up with carbon build-up since it's responsible for recirculating a portion of your exhaust fumes for environmental protection. If your engine's performance is waning and your ride has problems starting and your gas mileage is continuously getting lower, it's time to purchase a replacement part. With our handy Loan-a-Tool program, installing your Mercury Grand Marquis EGR valve replacement is fast and easy. You can also benefit from AutoZone's free battery charging and engine diagnostic testing the next time you drop by your local store.
