Tires on a car that sits may develop flat spots in as little as 30 days.Īfter several months of sitting in the same place, those flat spots may not go away after driving.įor the those who drive their classic car just a few times a year, here's an easy way to keep your tires from flat-spotting.Įvery couple of weeks, put the transmission in neutral and roll the car a forward (or backward) a foot or two. The phrase 'battery tender' is a brand name, and they are one of the more popular battery maintenance devices. Top off with water if necessary, and allow to stand for an hour before charging.Ĭonstant-current chargers are often called smart-chargers, because they can vary the charging voltage to keep current constant. Also check fluid level if it's a non-sealed battery. If radiator hoses or heater hoses show any signs of cracking, replace them before they become a problem.Ĭheck connections for tightness and corrosion. Engine coolant is under pressure!Įngine compartments get very hot, causing rubber hoses to get hard and brittle over time, which leads to breakage.

This causes friction, which increases mechanical wear, and allows carbon deposits and sludge to build up. After a certain point, it loses certain lubricating qualities. Engine oil deteriorates over time and use.
