Hyundai/Kia Theta Engine Inspection Essentials
The Hyundai Theta engine appeared in 2006 Sonata models and is going strong to this day in naturally aspirated and turbocharged forms in various Hyundai and Kia applications. The one area of the engine that has been the source of more TSBs and tech tips has been the bottom end of the engine and lubrication system.
Air Conditioning Odor Causes And Cures
Air conditioning odors typically result from the uncontrolled growth of bacteria and other microorganisms in the evaporator. Research by independent laboratories has found fungi such as Aspergillus, Cladesporium, Penicillium and others growing on cooling coils and other A/C system areas.
The Carbon Deposit Conundrum
Engine carbon deposits have been around for more than 100 years. They start out as fresh oil and gasoline. The engine uses heat, compression and combustion to turn most of the fuel into power. But, during some combustion events, a droplet of fuel or oil is transformed into a substance that can become a carbon deposit. This typically happens when there are conditions that are outside of the normal operating conditions.

The Oil And Carbon Deposit Connection
Oil is made of carbon atoms. The oil in the crankcase is a highly refined carbon-based substance that is found in long chains with strong bonds that are typically uniform in size and shape. They work well together to lubricate the engine and protect the bearings, as they are engineered to withstand extreme temperatures.
Flash Or Pass? Don’t Leave Money On The Table
These days, nearly every car on the road has multiple on-board computers. They often need to have their software updated or be reflashed because a component has been changed or upgraded.
Curing Carbon Deposits On Direct Injection Engines
Direct injection improves fuel economy by injecting the correct amount of fuel for the conditions in the combustion chamber. But, it is not a perfect science: Carbon deposits can form on the intake valves, piston and other surfaces in the combustion chamber.

Spark Plug Diagnostics
If you are replacing spark plugs to solve a misfire problem, you might want to take a look at the original plugs to make sure you are replacing them for the right reasons. Most original equipment spark plugs have a life of more than 100,000 miles thanks to electrodes that contain precious metals like platinum and iridium. If the plugs fail sooner than the recommended interval, solve the problem before installing new plugs.
