EMISSIONS & EXHAUST SYSTEMS
What is it?
Your car’s emission system keeps the engine running cleanly and efficiently in all sorts of operating conditions. If your car’s engine isn’t performing up to par or the “Check Engine” light goes on, have it inspected immediately. Failure to do so can reduce your mileage per gallon of fuel or cause your vehicle to pollute.
What does it do?
Your car’s emission system controls the emissions, exhaust and pollutants 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 prevents harmful gasoline vapors from escaping at the fuel tank.
Typical Wear and Tear includes:
• Driving and atmospheric conditions
• Mileage
• Vehicle age
• Type of spark plug electrode material
• Maintenance history
• Poor spark
• Bad fuel
• Damaged or worn sensors
Maintenance Tips:
EMISSIONS
• Replace PCV valve every 30,000 miles
• Replace oxygen sensor every 30,000 miles
• Replace air filter every 10,000 miles
• Check choke and linkage every 30,000 miles
• Check crankcase vent filter every 20,000 miles
• Replace vapor canister and hoses at 50,000 miles
• Conduct and emissions analyzer test every 30,000 miles
EXHAUST
• Check for leaks in exhaust every 20,000 miles
• Check hangers and exhaust system supports every 20,000 miles
• WHEN A CATALYTIC CONVERTER FAILS, IT IS ILLEGAL TO INSTALL A JUNKYARD REPLACEMENT
