Oil Change

3 Examples of Services at Your Cadillac Dealership That Extend Life

Oil Changes

High-quality oil is essential to keep your engine performing at its best. Oil protects countless engine components from friction damage by lubricating them so they move smoothly and efficiently. The oil’s continuous movement helps cool hot components to further reduce wear and tear. Finally, specialized oil additives keep the engine clean, protect against rust, and break down potentially harmful engine buildups.

Oil changes are important, as even the best oil loses its efficiency as it slows down and thickens. Slow, thick oil provides less lubrication, causing engine parts to wear out faster. Its additives also weaken, causing rust to develop, and carbon buildup will begin, both of which can result in major engine damage. We drain and replace the oil and install a new filter to prevent these issues.


Coolant Replacement

The engine runs most efficiently at a temperature between 185°F and 220°F, but sustained high temperatures can damage sensitive engine components. The cooling system uses coolant, which is pumped through the engine to absorb heat and transport it to the radiator for removal by heat exchange. This system will also speed up or slow down as needed to keep the engine at its optimum temperature.

Coolant absorbs dirt and other debris during its travels through the engine, and this accumulated debris makes it move slowly. Slower-moving coolant can’t remove heat fast enough, which causes the engine temperature to rise. If the temperature under the hood gets hot enough, the engine can suffer serious damage. Regularly replacing the coolant protects the engine and allows it to keep working for a long time to come.


Air Filter Replacement

Efficient combustion requires vast quantities of clean air. The air filter, housed in a box just inside the radiator grille, traps dust, dirt, and other debris before the air enters the engine. As time passes, this filter will become clogged with dirt, which severely restricts airflow into the engine. Without enough air, the fuel-air mixture will become fuel-rich.

A fuel-rich engine wastes fuel, as the lack of oxygen means much of it won’t burn and is dumped into the exhaust system. Poor combustion results, which can cause misfiring or stalling. Repeated stalling will damage the engine, particularly the cylinder and pistons. Installing a new filter prevents this damage.
