As a part of our Portland car tune-up service, we will examine all of the different belts and hoses in your vehicle. These days, the serpentine belts in your engine are designed to provide power to a number of different systems in your vehicle. The belts transform the mechanical energy generated from the up-and-down motion of the pistons into a circular motion, which is then used to provide energy for many other important systems in your vehicle. The alternator, A/C compressor, and power steering are just a few of the systems that rely on belts to function. Radiator and heater hoses carry vital fluids and help keep your engine from overheating. These belts and hoses are usually made of rubber.

Over time as the rubber is exposed to heat and friction it can become hard, brittle and weak. Rubber hoses can split or leak, and rubber belts can snap. If a belt snaps, then your vehicle will cease to function. A split hose can overheat your engine and cause significant damage, so it is important to check your belts and hoses regularly.

It can be difficult to assess damage to hoses and belts just by looking at them, as the damage often originates on the inside. If there is visible damage, then it is an obvious sign that your belts and hoses need to be replaced. Another good way to check the dexterity of your rubber belts and hoses is to pinch them with your fingers. If the rubber feels brittle and stiff, or if it feels squishy and soft, then it is probably time for a replacement. Most car owners neglect their belts and hoses and do not check on them regularly. Replacing worn-down belts and hoses can prevent more serious damage to your car’s engine.

With a K & M Auto Service oil change or any other service, you’ll receive a Touch® Courtesy Check. We’ll look inside, outside, under the hood and underneath the car, then explain the findings and give you a written report.

While you’re there, let us perform a Touch® Courtesy Check, which includes a visual check of the following items:

  • Engine air filter
  • Brake fluid
  • Power steering fluid
  • Automatic transmission fluid
  • Coolant/antifreeze
  • We’ll also walk you through your vehicle manufacturer’s recommendations for replacing these vital fluids and filters.

Oil Change – More than You Wanted to Know

Engine Oil
Most cars on the road today use multi-grade oil — one that can work efficiently in cold and hot weather. A multi-grade oil is rated by two numbers, such as 5W-30.

About the oil classification system.
Each engine oil comes with a classification indicating its viscosity, which is its friction or resistance to flow. In a multi-grade oil, the first number indicates how the oil will flow when it is cold. The lower the number, the lighter the oil and the better it will perform at lower temperatures. The second number indicates the thickness of that same oil at high temperatures. For example, a 5W-30 oil will flow as a 5-weight oil at zero degrees Fahrenheit and as a 30-weight oil at 210 degrees Fahrenheit

Why viscosity is a concern.
During cold starting, only a small amount of oil is present in the upper parts of engines. To lessen the friction when upper engine parts, such as the valve train, pistons, overhead cam and cam bearings, scrub against each other, a lower viscosity allows the oil to reach the components more quickly.

Why 5W-30 and 5w-20 oils are so popular.
Many vehicles today leave the factory with 5W-30 or 5w-20 engine oil. Vehicle manufacturers recommend them because they are lighter oils that perform well in a range of temperatures and help improve gas mileage.

Synthetic Oils
Not all motor engine oils are 100% petroleum. Synthetic oils, which are primarily chemically compounded lubricants, are also available. They can provide:

  • Higher viscosity stability over a wider temperature range
  • Reduced oil thickening
  • Reduced wear and increased load-carrying ability.

Which oil is right for your car?
The simplest and safest way to find out is to check your owner’s manual…or talk to your Midas mechanic.

Oil Filters
Oil filters are designed to trap foreign particles suspended in the oil and prevent them from getting to the engine bearings and other parts.

Your vehicle relies on a variety of fluids to operate its brake, steering, transmission, engine cooling and other systems. When these fluids become degraded or are at incorrect levels, damage to other components may occur…so always follow the manufacturer-recommended service schedule.

Automatic Transmission Fluid
This is typically an oil-based fluid used in a transmission that lubricates and cools the transmission and provides hydraulic pressure to shift gears automatically.

Brake Fluid
This is the hydraulic fluid used to transmit pressure through the brake lines in a brake system providing stopping power and protecting hydraulic brake components from internal corrosion.

This is the mixture of water and antifreeze used in an engine cooling system to dissipate heat and maintain the engine’s temperature throughout its operating range.

Starting & Charging
The battery starts your car, powers on-board computers and supplies emergency power needs. A weakened battery causes stress on alternators and starters, especially during extreme temperatures. Let Midas test and inspect your battery regularly.

Air Filters
Clean air filters can increase engine performance, boost fuel mileage and reduce engine wear. Cabin air filters can minimize airborne contaminants in the passenger compartment and improve heating/cooling efficiency.

Touch® Courtesy Check
The Midas Touch® Courtesy Check is fast, efficient and covers many items on your vehicle’s preventive maintenance schedule. We’ll conduct a visual check, looking inside, outside, under the hood and under the vehicle, then provide you with a written report.
