Denny Hamlin and Joey Logano finished 3rd and 4th, respectively, in the NASCAR Chase, giving both a JASPER 4-Speed Transmission and a Differential places in the Top-4 finishes of the Championship run. Congratulations to Kevin Harvick on winning the 2014 NASCAR Championship, as well as on a great racing season.
The engine cooling system affects your car’s overall dependability and engine longevity. Cooling systems have advanced over the years with new coolant formulations and new radiator designs and materials. If you suspect a problem with your cooling system, you should check it immediately.
What does it do? The key parts of the cooling system remove heat from the engine and automatic transmission and dissipate heat to the air outside. The water pump circulates coolant through the engine. The coolant absorbs heat and returns it to the radiator where heat is dissipated. The thermostat regulates the coolant temperature to keep it consistent for efficient engine operation.
Your car’s exhaust system has come a long way from the old days of exhaust pipes and mufflers. Today, the exhaust system is safety and emissions control rolled into one. Have your car’s exhaust system inspected regularly and check it immediately if you suspect any problems.
What does it do? The exhaust system routes dangerous exhaust gas from the engine out and away from the car to keep from affecting the occupants. Next, the exhaust system reduces exhaust noise from the engine. The catalytic converter reduces the level of harmful pollutants in the exhaust. The oxygen sensors mounted in the exhaust system monitor the level of oxygen in the exhaust gases to maintain efficient engine operation and to monitor the converter’s operation.
A program designed to periodically check vehicle emissions to ensure they are within limits. Often referred to as an I/M (Inspection/Maintenance) program, they are used in numerous states and areas as required by the Environmental Protection Agency to improve air quality in those areas.
Your car’s emission system keeps the engine running cleanly and efficiently in all sorts of operating conditions. A steady or flashing warning light on your vehicle dashboard indicates a problem that is currently happening and may require immediate attention. Failure to do so can reduce your gas mileage or cause your vehicle to pollute.
What does it do? Your car’s emission system controls the emissions, exhaust and pollutants (including gasoline vapors escaping from the fuel tank), using an array of sensors, computerized engine controls and the exhaust components. The emission system substantially reduces harmful gases such as carbon monoxide (CO), unburned hydrocarbons (HC) and oxides of nitrogen (NOx) and, by law, must be maintained in operating condition.
