thickness gauge
Glossary “thickness gauge” Definition:
Strips of metal made to an exact thickness, used to measure clearances between parts.
thickening agent
Glossary “thickening agent” Definition:
Added to grease to achieve the proper viscosity or other required properties. It is usually a soap such as aluminum, lithium, sodium, or sodium. It may make-up 5 to 25% of the grease by volume.
thick film integrated module (TFI)

Thexton
Glossary “Thexton” Definition:
Aftermarket tool manufacturer
thermosyphon
Glossary “thermosyphon” Definition:
Flow of coolant in a heat exchanger, such as a radiator, that is possible by the difference in densities of heated and cooled fluids.
thermostatically controlled air cleaner (TCAC)
Glossary “thermostatically controlled air cleaner (TCAC)” Definition:
Device used to regulate the temperature of the air entering the engine air cleaner as an aid in reducing emissions. May be also referred to as an EFE.
thermostatic vacuum valve (TVV)
Glossary “thermostatic vacuum valve (TVV)” Definition:
Valve that is operational with a vacuum signal that is proportional to an applied temperature.
thermostatic vacuum switch (TVS)
Glossary “thermostatic vacuum switch (TVS)” Definition:
Valve that controls the passage of vacuum according to temperature, blocking vacuum until a certain coolant temperature is reached, at which point it opens.
thermostatic switch
Glossary “thermostatic switch” Definition:
Term used for thermostat.
thermostatic pressure valve
Glossary “thermostatic pressure valve” Definition:
Valve that opens and closes in relation to temperature changes.
thermostatic gauge
Glossary “thermostatic gauge” Definition:
Type of gauge used to indicate fuel, engine oil, transmission and engine coolant temperature.
thermostatic expansion valve (TXV)
Glossary “thermostatic expansion valve (TXV)” Definition:
The component of a refrigeration system that regulates the rate of flow of refrigerant into the evaporator as governed by the action of the remote bulb-sensing tailpipe temperatures.
thermostatic de-icing switch
Glossary “thermostatic de-icing switch” Definition:
Thermostat that prevents the evaporator from icing up due to low temperature conditions.
thermostatic clutch control
Glossary “thermostatic clutch control” Definition:
Method of temperature control using a thermostat to cycle a clutch on and off.
thermostatic air cleaner
Glossary “thermostatic air cleaner” Definition:
Engine air cleaner assembly that controls the temperature of the intake air by blending relatively cool underhood or outside air with relatively hot air picked up from a shroud over the exhaust manifold.
thermostat bypass
Glossary “thermostat bypass” Definition:
Small passage way that allows coolant to circulate when the thermostat is closed.
thermostat
Glossary “thermostat” Definition:
1). Driver operated device used to cycle the clutch to control the rate of refrigerant flow as a means of temperature control. 2). Temperature sensitive component located in a housing at the coolant outlet of the engine that restricts coolant flow to the radiator to maintain the desired engine-operating temperatures.
