Coolant Flush

Importance of a Coolant Flush

Engine coolant is also called antifreeze, and it’s a heat-transfer fluid that removes extra heat from the engine. Coolant comes in various types, so you have to pick the right one for your vehicle. Often, your owner’s manual tells you the right one to use. Your engine creates a lot of heat and energy while it moves. The cooling and exhaust system keeps the engine cool. Since the antifreeze gets used so much and recycled, you may need a coolant flush periodically to keep everything running smoothly. Often, an auto mechanic is the best person to perform this service.

Flushing the coolant system offers many benefits to your vehicle. Maintaining the cooling system is essential because it is part of the automobile. Generally, these flushes are done once a year, though your mechanic at Elder Auto Complete Auto Service may recommend it be done more often if you drive more frequently. If you have never had a flush done of the coolant system, you may wonder if it is needed. You can talk to the friendly mechanics and staff here and get advice. They are going to help you find the right services and repairs based on your particular needs.

Flushing the coolant system is often necessary for auto repair. It is designed to remove scale and rust deposits that can build up with time. If you don’t get them out of the system, they can damage the cooling mechanisms and overheat the car. Plus, newer antifreeze products have additives that can lubricate the water pump. This does extend the life of the part, but the lubricant inside the coolant doesn’t last forever. Therefore, you need to have it changed once a year, at least. You can easily check to see if it is time for this service, or you can ask a mechanic you trust to tell you when to have it flushed.

Littleton Drivers: Is It Time To Replace Your PCV Valve?

Improved fuel economy has two benefits for Denver car owners: less fuel is necessary and fewer emissions are released. Littleton cars and trucks run cleaner than ever. Denver auto owners may not realize that the first federally mandated pollution control device came out almost fifty years ago.

CO car owners that were around in the early 60’s may remember that the PCV Valve came out on 1964 model cars. PCV stand for Positive Crankcase Ventilation. Littleton Drivers: Is It Time To Replace Your PCV Valve?The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine.

When fuel is burned in the minivan engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.

Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to dangerous sludge. Sludge is like Vaseline and clogs passages in the engine leading to damage.

Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in Denver.

Enter the PCV valve. It’s a small, one-way valve that lets out the 
detrimental gases from the crankcase, and routes them back into the air intake system where they are re-burned in the engine. Fresh air comes into the crankcase through a breather tube. This makes for good circulation in the crankcase. And that gets the harmful air out. As you can imagine, however, the valve gets gummed up over time.

Littleton drivers that skip oil changes now and then will notice that the PCV valve gets gummed up even faster. If the PCV valve is sticking in your minivan, the gases won’t circulate as well, leading to increased pressure in the crankcase. That, in turn, can lead to oil leaks. Fortunately, the PCV valve is very inexpensive to replace at Elder Auto in Denver. Some can even be checked by your considerate Elder Auto advisor.

Your minivan car makers usually recommend they be changed somewhere between twenty and fifty thousand miles. Unfortunately, PCV valve replacement is left out of some minivan owner’s manuals, but at Elder Auto, we will make sure your PVC is replaced if needed.

All of us Littleton car owners can do our part for the environment. Watch that lead foot, stay on top of our critical automotive maintenance and don’t forget to replace our PCV valve.
