2002 SE, lower front end damage from someone loosing their trailer spare on the freeway. No external body/nose damage, but the semi-rigid black plastic "air dam" (deflector?) directly below the nose shattered. Looked at the service manual, but unable to identify (name & part number) of this piece. Temp gauge shows higher operating temps (loss of air flow to the radiator?), so replacement is needed before warmer weather arrives. Looked in some salvage yards, but all are damaged as bad or worse. What is this part called? Maybe I can find used ones on eBay.
