Lincoln towncars have some parts that are specific to the 1991 and 1992 model year. And some of these parts are also used in the 1992 crown victoria and mercury grand marquis.

On the left is the plastic 7-groove power steering pump pulley that was used in the 1991 towncar. Note that the center hub that connects to the pump shaft is metal.
On the right is the solid metal 7-groove power steering pump pulley

The hose on the top is from a 1991 lincoln towncar. The electrical switch on the pressure hose is to raise the idle speed so that the engine doesn't stall when the car is moving slowly and you turn the steering wheel.

The hose at the bottom is a new aftermarket pressure hose.

Here is the belt tensioner from a 1991 towncar. The front timing cover in the 1991-1992 towncar didn't have any mouting bosses for the tensioner like the later cars do. And the tensioner assembly connected directly to the studs which hold the front timing cover onto the engine. The bracket at the top of this assembly is for mounting the ignition coil packs.

Aftermarket replacement tensioners for the early 1991-1992 vehicles have an additional idler pulley that the original oem unit didn't.



And here are a few pictures of the 7-groove front engine accessory drive setup on a 1992 crown victoria

The engine has lots of sand on it, but this appears to be a common occurence when one lives in the iraq desert like vic1992LX does.
