Communicates the engine coolant temperature to the ECM to ensure proper air/fuel ratio, cooling fan and temperature gauge operation.
Thermistor placement within the housing matches original design to ensure proper output.
Proper thermal conductive grease to provide accurate temperature transfer to the thermistor.
Causes for replacement: check engine light, no/erratic gauge operation, no/erratic cooling fan operation, engine overheating.
Causes for replacement: rough idle, engine hesitation, poor fuel economy, failed emissions test.

For best performance, follow the manufacturer's recommendations in your vehicle owner’s manual..
Cleans, restores, protects the entire fuel system (fuel injectors, carburetors, intake valves and combustion chambers).
Restores: lost power, acceleration, lost fuel economy, and operation of the fuel gauge sensor.
Reduces: rough idle, engine surge, hesitation, and spark plus fouling.
Improves: cold start performance, and fuel stability for up to one year.

Using Cataclean can lower your total hydrocarbon emissions by up to 50 percent.
Reduces carbon build-up in catalytic converter, oxygen sensors, fuel injectors and cylinder heads which results in improved fuel efficiency.
Improves overall vehicle performance-including driveability issues such as power reduction, hesitation, rough idle, hard starts and lost fuel economy.
Safe for gasoline, diesel, hybrid and flex-fuel vehicles.
Not for use in 2-stroke or oil / gas mix engines.

Quickly dissolves gum, varnish, fuel residues, and other deposits from carburetor, PCV valve, automatic choke, carburetor linkage, throttle body, and distributor shaft with H.E.S.T. for maximum performance and fuel economy..
Improves drivability by removing deposits that cause rough idle, stalling, and loss of acceleration..
