The splash pan, gravel shield, and maybe others.

Your brick may have none, they do wear and fall off and then the car gets a "New-to-Volvo" owner. Maybe you?

It is a large plastic piece, maybe 2 ft by 3 ft, that is carefully shaped and fits under the front part of the engine from the cross member to the radiator support bar. If you look down behind the radiator, you should NOT be able to see the ground below the car.

If you have no such pan, get one. they protect the alternator and front engine harness and oil pan from attach of the road oils, gritties, water, gravel, etc.

Several Brickboard advertisers will have them. I found one in a junkyard only after years of looking. If you get one without the mounting bolts, someone here will know the size and length, and what washers to use, too.

Good Luck,

Bob
