(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

Uncontrolled explosion of fuel causing pinging or damage.
knock (detonation)
Circulates coolant through the engine and radiator.
water pump
The small gap between the valve stem and rocker arm.
valve clearance (lash)
Removes contaminants from engine oil.
oil filter
Connects the crankshaft and camshaft so valves open at the correct time.
timing belt / chain
Seals the surfaces between parts to prevent leaks.
gasket
The main structure of the engine that holds the cylinders and supports other parts.
cylinder block
Measures how much pressure leaks from a cylinder.
leak-down test
System that recirculates exhaust gas to reduce emissions.
EGR (exhaust gas recirculation)
Helps keep the engine spinning smoothly and connects to the transmission.
flywheel
Regulates engine temperature by controlling coolant flow.
thermostat
Connects the piston to the crankshaft.
connecting rod
Checks the engine’s ability to compress air/fuel.
compression test
Measures engine vacuum to diagnose internal problems.
vacuum gauge
Holds the engine oil at the bottom of the engine.
oil pan
Delivers fuel from the tank to the injectors.
fuel pump
A measure of oil’s thickness or resistance to flow.
viscosity
Opens and closes the engine’s valves at the right time.
camshaft
A code identifying a specific problem.
DTC (diagnostic trouble code)
Creates a spark to ignite the air/fuel mixture.
spark plug
Prevents oil or coolant from leaking out of rotating parts.
seal
Control the flow of air/fuel mixture in and exhaust gases out.
valves (Intake/Exhaust)
Converts the up-and-down motion of pistons into rotary motion.
crankshaft
Terms describing assembled engine sections (short block = lower end; long block = includes heads and valvetrain).
short block / long block
The top part of the engine that closes the cylinders and contains valves and spark plugs.
cylinder head
Reduces friction between moving engine parts (e.g., crank bearings).
bearing
Electronic device used to read trouble codes and data.
scan tool
Point where the piston is at the top of its stroke.
TDC (top dead center)
Tool used to tighten bolts to a specific tightness.
torque wrench
The proportion of air to fuel in the mixture.
air-fuel ratio
Moves up and down inside the cylinder to create compression and power.
piston
Fluid that removes heat from the engine.
coolant / antifreeze
Ratio between cylinder volume at bottom and top of piston travel.
compression ratio
System that removes gases from the crankcase.
PCV (positive crankcase ventilation)
Cools the engine coolant by air flow.
radiator
Sprays fuel into the engine for combustion.
fuel injector
Area where fuel and air are burned to create power.
combustion chamber
System that monitors and reports engine faults.
OBD-II (on-board diagnostics)
Reference points used to align the camshaft and crankshaft.
timing marks
Circulates engine oil to reduce friction.
oil pump
