The cooling system removes heat from the engine, allowing it to work effectively and protecting it against overheating. In time, its components can become worn or damaged. As your Lincoln dealership, we want you to know some signs you need to visit us so the system can be checked or repaired.
3 Signs It’s Time to Visit Your Lincoln Dealership for a Cooling System Check
Coolant Leak
Coolant is a mixture of antifreeze and water, and it’s able to absorb heat. This liquid is pumped through the engine, absorbing heat radiating off the hot components. The trapped heat is transported to the radiator inside the coolant, where it enters rows of thin metal tubes. Airflow through the radiator grille flows over the tubes, removes the heat, and the coolant continues to circulate through the engine.
Worn radiator hoses, damaged seals, or a rusted radiator can all result in a coolant leak. As coolant is lost, pressure in the system drops, and the remaining coolant slows down. This causes the engine temperature to rise almost immediately. Left unchecked, the engine will overheat and suffer major damage. We’ll find the leak and repair it, then refill the coolant.
Broken Thermostat
The thermostat is a small component that controls the release of coolant. When the engine temperature increases to approximately 180°F, the thermostat opens, releasing coolant. The coolant is then pumped through the system by the water pump. The coolant continues to circulate until the temperature drops below 180°F, then the coolant is withdrawn.
Age or damage can cause the thermostat to jam. If it jams open, coolant will be released regardless of the current engine temperature. The engine temperature will drop below its normal, efficient operating temperature, and your Lincoln will use more fuel. If the thermostat jams closed, no coolant will be released, and your engine will rapidly overheat. We can replace the thermostat in minutes to fix this issue.
Broken Radiator Cap
The radiator cap is located on the top of the radiator. It controls the pressure in the coolant system and prevents leaks. The cap screws tightly into the radiator and is secured by rubber seals. If the system pressure rises too high, the cap will open to release excess pressure, then close again. As time passes, the seal can shrink or crack, and coolant will leak.
This type of leak is easy to spot, as the coolant will evaporate almost instantly in the heat of the engine and leave white streaks around the cap. We’ll examine the cap and replace the seal or install a new cap if required.
Most coolant system problems are fast and inexpensive to repair and will prevent engine damage. Schedule a Service Appointment today at Biondi Lincoln in Monroeville, PA.
