Brake Room
This component squeezes the brake pads against the rotor.
What is a brake caliper?
These raised bars in the tread grooves indicate when a tire reaches its tread-wear limit.
What are wear bars?
This is required before performing any engine replacements or use of strait time over 1.0 hours.
What is district parts and service manager authorization?
This cooling-system component regulates coolant flow based on temperature.
What is a thermostat?
This ignition component creates the spark inside the combustion chamber.
What is a spark plug
This brake component uses engine vacuum or another power source to reduce the driver’s pedal effort.
What is a brake booster?
This alignment angle describes the tire leaning inward or outward when viewed from the front.
What is camber?
Part of the three c's this is the detailed description of how we determined the failure.
What is the Cause?
The cooling-system cap raises the coolant’s boiling point by maintaining this.
What is pressure?
Oil entering the combustion chamber commonly produces exhaust smoke of this color.
What is blue or blue gray smoke?
Brake fluid is described as “hygroscopic,” meaning it absorbs this.
What is moisture?
A sawtooth or feathered tread pattern commonly points to an incorrect setting of this alignment angle.
What is Toe?
This sheet displays a list of diagnostic trouble codes and is required any time a trouble code related repair is made under warranty.
What is a dtc printout?
A cooling-system pressure test should not exceed this specified limit.
What is the manufactures specified test limit?
Positive fuel trim means the engine computer is doing this to the commanded fuel amount.
What is fuel trim?
A rotor can develop this thickness condition that contributes to brake pedal pulsation.
What is rotor runout? Or What is disc thickness variation?
A tire can be balanced correctly but still cause vibration because its stiffness varies as it rolls. This loaded test helps identify it.
What is road force?
This is required documentation any time a warranty brake repair is needed.
What is a brake worksheet?
This test checks for combustion gases entering the cooling system.
What is a compression test?
A misfire moves to another cylinder after two ignition coils are swapped. This component is the likely cause.
What is an ignition coil?
A restricted brake hose may allow pressure to apply the brake but prevent its release, causing this condition.
What is brake drag?
During a controlled diagnostic tire swap, a vehicle’s pull changes direction. This points toward this source of the pull
What is a tire pull?
This is needed any time 2 components of the same system are replaced in order to account for overlap.
What is strait time?
In a cylinder leak-down test, air heard escaping from the throttle body points toward leakage past this.
What is an intake valve
Fuel trims are strongly positive at idle but move closer to normal at higher RPM. This pattern commonly suggests this type of leak.
A vacuum leak or unmetered-air leak
