Cold Start Injector

An auxiliary fuel injector which injects additional fuel into the intake manifold during cold engine starting and operation

Cold Weld

A method of repairing small cracks in blocks and heads by using tapered plugs to fill the cracks.

Cold Working

The deformation of metallic material at a temperature below the recrystallization temperature, resulting in strain hardening of the material

Cold-cranking Amps (CCA)

A common term used for cold-cranking power rating. The number of amperes a fully charged lead acid battery can deliver for 30 seconds at 0o without the cell voltage dropping below 1.2 volts per cell or 7.2 volts of a 12 volt battery

Cold-cranking Power Rating(CCP)

The number of amperes that a fully charged battery will deliver for 30 seconds at 0 F (-17.8 C) without the terminal voltage dropping below 7.2 volts.

Cold-engine Lockout Switch

A switch that sends a signal to the body-control module, or controller, to prevent an action, such as blower-motor operation, until the coolant in the engine has risen to a predetermined temperature.

Cold-rolled Steel (CRS)

Carbon steel that is worked into shape while cold.

Cold-solder Joint

A loose or intermittent electrical connection, caused by poor soldering techniques.

Cold-start Injector

An electronic fuel-injection system that supplies extra fuel to the engine for cold starting.

Cold-start Test

A prescribed federal test procedure for measuring emissions before an engine has warmed up after a 12-hour cold soak at 68 F to 78 F (20 C to 25.6 C).

Cold-start Valve

A valve that permits additional air into the intake manifold during a cold start on a fuel-injected engine.

Cold-weather Modulator

A thermostatically controlled check valve that traps vacuum in the vacuum motor circuit when the car is accelerated hard at any temperature below 55 F (12.8 C), to prevent hesitation by allowing heated air to enter the engine.

Collapsible Steering Column

An energy-absorbing steering column that is designed to collapse if the driver is thrown into it due to a heavy collision.

Collapsible Washer

A washer that crushes when a nut is tightened against it

Collateral

Property offered to support a loan that can be seized if you default.

Collect

A term used for valve keeper.

Collectible Car

See collector car.

Collector

1. A device that collects exhaust gases from the primary tubes and channels them into a single exhaust pipe. 2. The tank of a radiator that receives the fluid before it passes through the radiator. Transistor part (Emitter, Collector, Base)

Collector Car

Typically, a vintage vehicle that is valued by automotive enthusiasts, although there are some new vehicles that are prized by automotive collectors, too. To become a collectible, a car or truck typically has to have been produced in relatively small numbers, and it must offer styling, performance or other characteristics that set it apart from other vehicles of its vintage. Since many vehicles were produced in small quantities because they were unpopular, rarity alone is no guarantee of collectibility.

Collector Muffler

An exhaust system component that is used to reduce engine noise in drag race applications. The collector muffler mounts right after the header, at the header collector. Many high-performance designs flow just as well as open exhaust, and some even improve performance when compared with an open exhaust system.
