Engine Oil

Engine oil is what lubricates a car’s engine, allowing it to run smoothly and last longer. Car owners must maintain their cars’ engines by changing the oil and using the oil appropriate for their cars’ makes and models. Every car comes with a check oil light and an oil filter under the hood. These components allow car owners to monitor their oil levels and add oil as needed without having to hire a mechanic.

Changing the Oil

An important part of routine car maintenance is changing the oil regularly. The necessary frequency of oil changes has become a point of contention among experts. The Engine Oil Bible maintains that engine oil can’t be changed often enough, but Nordic Group insists that, with the advent of detergent oils and multi-weight oils, some vehicles can go as far as 6,000 miles before needing an oil change. The best course of action is to check the owner’s manual and follow the manufacturer’s recommendations.

An obvious benefit of changing one’s own oil is saving money, but oil change services frequently advertise bargains. If the check engine oil light comes on when you’re driving, this is a strong indication that the car is running low on oil. A driver does not need a mechanic to add oil. However, if the oil light stays on or lights up shortly after adding oil, there may be a leak, and a mechanic should look at the car.

The air conditioning unit in your vehicle operates similarly to a refrigerator. Your vehicle’s air conditioning unit is designed to move heat from the inside of your car to outside of it.

Your vehicle’s air conditioning unit has six major components:

The refrigerant carries heat. In modern cars, the refrigerant is a substance called R-134a. Older cars’ refrigerant is called r-12 freon, which is more expensive and difficult to find than R-134a.

The compressor circulates and compresses refrigerant within the vehicle’s cooling system.

Your vehicle’s condenser changes the refrigerant from gas to liquid and expels heat from the car.

The expansion valve (sometimes called the orifice tube) is a nozzle that simultaneously drops the pressure of the refrigerant liquid, meter its flow and atomize it.

Your vehicle’s evaporator transfers heat to the refrigerant from the air blown across it, cooling your car.

The receiver or dryer filters your vehicle’s refrigerant and oil, removing moisture and other contaminants from them.

When you start your vehicle’s air conditioning system, the compressor works by putting the refrigerant under pressure, sending it to the condensing coils, which are generally in front of your vehicle’s radiator. The condenser expels hot air outside the car, cooling the air within the vehicle. When this happens, the refrigerant is cooled, and it changes from a gas to a liquid, which then passes through the expansion valve and to the evaporator.

Once the evaporator receives the liquid-state refrigerant, it loses pressure and cools the remaining liquid. The vehicle’s blower moves air across the evaporator and into the vehicle’s interior. If you keep your air conditioning unit turned on, the refrigerant goes through this cycle continuously.

If any of these components is damaged, it can turn your cool car into a furnace during the summer months. Your vehicle’s air conditioning issue could be as simple as topping off refrigerant to replacing a valve. When your air conditioning unit is not working as it should, bring your vehicle to RPM Auto Specialists. One of our trained air conditioning specialists will inspect your car’s air conditioner, all lines, the evaporator and the compressor for leaks and wear.

Your vehicle’s radiator helps keep your engine cool. Overheated engines can lead to numerous problems, including eventual breakdowns. Your vehicle’ radiator sits at the front of the engine bay; it’s made up of slim, hollow channels that run between the inlet and outlet tanks. Coolant pumps through tubes to the engine, where it is warmed. Once the coolant reaches the engine, it goes to the radiator, which is constructed to cool the flowing liquid using the air passing the radiator. The cooled liquid cycles back through the engine, where it absorbs more heat. This cycle allows the engine to keep working at ideal temperatures.

If your vehicle overheats, you may need to have your radiator serviced or replaced. An elevated temperature gauge is another sign that your radiator might be malfunctioning. Puddles of green, yellow or orange coolant under your car could indicate that there is a radiator leak, which could be caused by corrosion. If you notice any of these signs that your radiator needs to be serviced or replaced, bring your vehicle to RPM Auto Specialists. Our Douglasville auto technicians can fix leaks or replace your vehicle’s radiator so you can get back on the road worry-free.

If you’re concerned about passing emissions or you already know your exhaust system isn’t what it should be, visit RPM Auto Specialists in Douglasville.

We are a full-service exhaust repair center and can do everything from simple leak repair to designing and building complete custom exhaust systems. We also replace hundreds of catalytic converters and can deal with any and all exhaust manifold leaks including those cases where studs have broken off in the head.

If you live in a larger city, you may be subject to emissions testing. If you fail your emissions test, you may need to get your exhaust system repaired or replaced. The team at RPM Auto Specialists can diagnose and repair your exhaust system and help you pass your emissions test.

While your exhaust system helps reduce noise output from your vehicle, it also significantly reduces harmful emissions from being released into the air. When your muffler and exhaust system functions properly, it significantly reduces your vehicle’s harmful impact on the environment. It also significantly improves the functionality of your vehicle.

Your vehicle’s exhaust system involves several components. The exhaust manifolds right behind the engine collect exhaust gases and connect to cylinder heads. Gases collected by your vehicle’s exhaust manifolds are analyzed by oxygen sensors and refined by catalytic converters before being muffled by the mufflers. By the time these gases reach the muffler, the emissions system has made your car run smoother, quieter and cleaner.

If any of the components of your vehicle’s exhaust system fail, your gas mileage and quality of air around you can be affected. The expert team at RPM Auto Specialists can inspect and repair your entire exhaust system to ensure your vehicle is running cleanly.

Tire pressure monitoring systems can save lives.

Most people ignore their tires, yet tires are undoubtedly a critical safety component on a vehicle. Where the rubber meets the road affects traction, handling, steering, stability, and braking. Because of this, sudden tire failure can have serious consequences, especially if it occurs when operating at high speeds.

• Nearly 250,000 accidents occur in the United States per year due to low tire pressure.
• About 75 percent of roadside flats are preceded by a slow leak or under-inflation.
• According to a recent survey, America could reduce its fuel consumption by 10 percent and save a collective $2 billion a year by keeping tires properly inflated.
• The National Highway Traffic Safety Administration estimates that tire pressure monitoring systems could prevent as many as 79 deaths and 10,365 injuries each year in the United States.

What are the effects of under-inflation?

Annually, an estimated 23,000 accidents and 535 fatal accidents involve blowouts or flat tires. Maintaining proper tire air pressure is not only a major safety concern but can also affect the handling and performance of your vehicle.

Why is it more expensive and time-consuming to have tires serviced rather than rotated?

Technicians use special diagnostic tools to test and recalibrate sensors any time a tire is moved from one location on the vehicle to another. A sensor must be tested to make sure it is functioning correctly and also must be reprogrammed whenever tires are moved from one position to another during rotation. OEMs recommend a sensor service kit be installed every time a tire is serviced. These kits include replacement parts to properly service the sensor. Sensors are powered by a battery that usually has a life of 6 to 8 years. The sensor has to be replaced when the battery fails because the sensor’s batteries are not replaceable.

We will first ensure all tires are at the correct, manufacturer specified inflation level. Next using a scan tool, we will determine if the vehicle’s system is functioning properly. If not we will isolate the problem and either repair it or direct you to one of our local and reliable partners to address the issue.

Today’s modern transmissions still require regular maintenance and we are your go-to shop. Each vehicle is different and we will help you decide which service is best for your vehicle and budget. From a simple drain and fill to complete service with new filter and gasket to removing and replacing conductor plates and valve bodies, we have done it all for years and will get your car shifting as it should. We do NOT perform transmission flushes as this is a practice the industry is moving away from due to the fact it often dislodges gum and varnish built up in the transmission leading to clogging of small passageways in the valve body which can lead to premature transmission failure.

Using the latest in state-of-the-art technology, we will install a safe and effective cleaner to suspend harmful varnish and sludge from the transmission valve body, torque converter and lines and install new high-tech fluid with conditioners.

Just like your engine, you should have your transmission serviced regularly. When RPM Auto Specialists services your transmission, we:

• Remove and inspect the pan
• Clean or replace the screen
• Clean the pan
• Reinstall the pan
• Install a new gasket
• Replace old transmission fluid with new, high-quality fluid
• Make any additional needed changes and adjustments

By replacing the old transmission fluid, the expert team at RPM Auto Specialists essentially gives your vehicle’s transmission new life. The new fluid restores your clutch’s holding power. This reduces slip and heat production. Additionally, flushing the old fluid gets rid of small bits of clutch material and metal shavings, which can damage your transmission by clogging passages and wedging themselves between moving parts. Getting rid of the old fluid reduces wear within the transmission.

Replacing old fluid with new also provides better lubrication within the transmission, which boosts the holding ability of the transmission’s friction components. Improved lubrication also results in less heat. By decreasing friction and heat, your transmission will work better for a longer amount of time. A simple service can save you the money and time that come with a major transmission repair or replacement.
