Why Do Engines Overheat?
Engines generally overheat for two reasons: 1) restricted water flow such as a stuck closed thermostat, clogged radiator, broken water pump belt or defective fan, and 2) low coolant level caused by a leaky radiator, leaky hose or hose clamp, gasket leak; defective radiator cap; or improper coolant level in the reservoir. Notice if green-colored coolant is leaking from your vehicle, this indicates a coolant leak and it must be repaired immediately. If a small puddle of coolant is under your car and is left unattended, this is the beginning of the end and will lead to a blown head gasket. A car leaking coolant is like a crying baby, it needs attention and should not be ignored! Proper cooling system maintenance is the best protection against blown head gasket Keep your cooling system clean. Flush it every two years. Change hoses and belts at specified intervals. Pressure test your radiator cap about half of all radiator pressure caps are defective. Do not over-tighten hose clamps or belt
