According to manners-expert Emily Post, dressy casual attire includes a sport coat, slacks and a nice shirt for men and a dress, skirt or elegant pantsuit for women. For men, a polo shirt is acceptable, as is a dress shirt or an open-collared buttoned-down shirt.
OLDSMOBILE Alero timing belts are a critical part of engine maintenance program and must be replaced at specified intervals determined by the belt manufacturer or original equipment vehicle manufacturer. Failure to do so may result in catastrophic engine failure.
Most dealers recommend changing the timing belt every 90,000 miles. Depending on driving habits and conditions the belt may last longer. I have heard of belts lasting 180,000 miles! The first gen LS's (1990-1994) have a non-interface engine, so if the timing belt breaks it's not going to damage the engine. If it breaks you'll just be stranded.
