Water Pump

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your vehicle from overheating. There are five main components to the cooling system: the radiator the radiator cap the hoses the thermostat the water pump The water pump's like the heart of your cooling system, circulating the fluid throughout your vehicle. It's a small pump that's driven by the engine; usually by belt, but sometimes by a chain or gear.The water pump only operates when the engine's running. Water pump failure is pretty routine. We see it often at Davis Automotive Repair. Some start failing at around 40,000 miles/64,000 km, but most fail by 100,000 miles/160,000 km. Consult your owner's manual or friendly and knowledgeable service advisor at Davis Automotive Repair to see what's recommended.Since a water pump either works or it doesn't, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fa ... read more

Coolant Service at Davis Automotive Repair

Centennial residents' vehicles have to operate in a wide range of Colorado temperatures which requires the engine coolant to be able to perform 'no matter what.' Think for a moment about the environment where the coolant does its thing. Very hot, high pressure, corrosive...And all the while, it has to protect the components of the cooling system from corrosion. These components are made from steel and aluminum, plastics and rubber. The coolant has to be formulated to protect against corrosion for all of these different materials. That's why vehicle manufacturer’s recommend different types of anti-freeze for our Centennial, Colorado, vehicles.There are several different 'families' of anti-freeze available to us here in Centennial. Your owner's manual will tell you what kind you should use. Of course, the automotive professionals at Davis Automotive Repair will know the right kind for your vehicle.It's important to stay on top of this because coolant system failure i ... read more

Keep Your Cool in Centennial

Centennial drivers rely on their vehicle's coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it's cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.There's a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that's easily reached inside your vehicle's engine, so it can turn to steam which does not conduct heat as well and is harder to contain.Also, if it's freezing outside in Centennial, the water in your engine could freeze while your vehicle is sitting out in the Colorado cold.So, if you remember your high school chemistry, you'll know that a mixture has both a higher boiling point and a lower freezing point ... read more

Coolant/Antifreeze Service at Davis Automotive Repair

Anyone who drives a car in Centennial knows that engines get hot when they run. But did you know that engines need to be cooled to keep running? Heat inside an engine can cause the metal parts to expand, which can seize up an engine and make it stop running. It can even ruin the entire engine! Good vehicle care requires keeping its cooling system in good condition.A vehicle's cooling system circulates water and antifreeze (coolant) through the engine where it absorbs heat. It then flows to the radiator where the water and antifreeze are cooled by the air that flows over the radiator. Then it circulates back into the vehicle's engine to absorb more heat.Why shouldn't Centennial auto owners just use water? Because water boils at temperatures that are often reached inside of an engine. Steam won't cool your vehicle engine and is hard to contain within the cooling system. The antifreeze keeps the water from boiling.So why do w ... read more

Smart Centennial Drivers Protect Against Overheating

Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for Centennial drivers to prevent. The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine and then flows to the radiator. Air passing through cooling fans on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again. The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage. Different engines require different types of coolant/antifreeze. The owner ... read more

Keeping Your Engine Cool in Centennial, Colorado

The cooling system keeps Colorado vehicle's engines from overheating while they are driving around Centennial. Its job is to move heat away from the engine. Let's talk about the various components of the system and how they make this happen.The radiator is the part most Centennial drivers associate with the cooling system. Coolant flows through the radiator which has fine cooling fins that draw the heat out of the coolant and dissipate it into the air. To make sure there's enough airflow over the radiator, a fan pulls air over the cooling fins even when the vehicle is idling.In some vehicles, the fan is powered by the serpentine belt. On others, an electric motor runs the fan. Electric fans turn on and off as needed. You may have heard the fan kick on shortly after you turn your vehicle off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.A hose connects the radiator to the water pump. T ... read more

Cooling System Components

Today we want to talk about a system in our vehicles – the cooling system. It's one of those things that Centennial auto owners don't give much thought to until it fails and then they're stranded by the side of a road in Colorado.Cooling systems fail more often than any other mechanical system – usually because of neglect. Don't you hate it when something breaks and you could have done something to prevent it?The good news is that if Centennial drivers take care of their cooling systems, they can keep working for the life of their car.Here at Davis Automotive Repair in Centennial, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, the thermostat, radiator, cooling fans, the heater core, the pressure cap, the overflow tank ... read more
