I have fluid stains or puddles under my car - what is it and where is it coming from?

There are a number of fluids that can leak from your vehicle, with many of them leading to a possible breakdown and expensive repair if neglected. Some leaks are obvious, where others may play “hide and seek” with you. If you can’t find the location of the leak, place fresh newspapers under where you think your leak is overnight and then check them in the morning. Following are some helpful hints as to the type of fluids used in today’s vehicles, as well as various colors and other characteristics to help you identify them.

What is a cabin air filter and why do I need it?

During the hot summer months, contaminants, such as pollen, dust, mold spores and smog, can easily enter a vehicle’s passenger compartment through the air conditioning, heating and ventilation systems, making the air in the car six times dirtier than the air outside.. Motorists can protect themselves and their passengers from these containments by replacing the vehicle’s cabin air filter annually or more often in areas with heavy containments, or whenever heating or cooling efficiency is reduced. Cabin air filters clean the incoming air and remove allergens. If your vehicle is model year 2000 or newer, there’s a good chance it is equipped with a cabin air filter. Check your owner’s manual. If the cabin air filter is not replaced, it can cause musty odors in the vehicle, and over time, the heater and air conditioner may become damaged by corrosion.

How can I prevent my car from overheating this summer?

Radiator Coolant, or anti-freeze as it is commonly known, works to combat both heat and cold – ensuring that your engine doesn’t freeze or over-heat. Over time and with exposure to the cold of winter and the heat of summer, the protective components of this fluid are weakened and its effectiveness can be dramatically decreased. Check and service your car’s cooling system every 48,000 km or every 2 years (for most vehicles) and pressure test the system and radiator cap to ensure they are in proper working order. The Great Canadian Oil Change Radiator Fluid Change will thoroughly flush your radiator and engine block, draining exhausted anti-freeze and replacing it with fresh, warranty approved coolant.

My "Check Engine" light is coming on, but there‘s plenty of oil and water in the car. What’s wrong?

When the “Check Engine” light comes on, your car is telling you to have the computer system checked out at the earliest possible opportunity. A “Check Engine” light means that your car’s computer system has recognized a fault in one of its circuits. It is different from the oil pressure light that means “STOP” driving the car.

What does SAE and API mean?

The A.P.I. (American Petroleum Institute) takes data from automobile manufacturers and determines what qualities motor oils must have to properly lubricate engines. Oil companies use this information to blend additives into petroleum base stocks to produce proper motor oils used in automotive engines The S.A.E. (Society of Automotive Engineers) oversees testing and sets standards for oil viscosities. On oil containers or labels the weight is noted as “SAE 10w30” (usually noted within or near the API Donut), meaning that in accordance with Society of Automotive Engineer standards, the viscosity of the product is a 10-weight in colder temperatures and a 30-weight in warmer temperatures. Note that the “w” between the 10 and 30 stands for “winter” (or colder). The “w” is included in all multi-grade oil labels as a sign that the first number is the cold viscosity measurement, while the second number is the warm viscosity measurement. With regard to tools, SAE refers to fractional measurements, non-metric. Many car manufacturers recommend a lighter weight oil be used in newer cars. Newer engines are built to tighter tolerances than before. This requires a lighter weight oil for proper lubrication when the engine is cold. Lighter weight oil also helps to increase fuel economy by a small amount. Most manufacturers will list a range of oils that can be used for different conditions. Some are for below 30°C, some are for above 40°C, or for towing or trailering. These weight ranges will be listed in your owner’s manual. If the oil is not listed in the manual, it’s not a good idea to use it.
