DaveJHM is correct. You have a V8 not a 6 cylinder. There never was or is a V6 in a 1990 Grand marquis. Click on the Estimate icon to get an estimate.
My thinking is that RepairPal limits models to 1990, and in the mid-80's there was a mid-size Marquis that had a 6 cylinder... Either way, hopefully the reader will answer.
