crossmember
Glossary “crossmember” Definition:
Part of the underbody structure of a vehicle that extends from one side of the frame to the other or from one side of the unibody to the other. Usually removable to gain access for repair.
crossover network

crossover pipe
Glossary “crossover pipe” Definition:
A pipe used to connect both sides of an dual exhaust system to equalize the pressure.
crossfire injection
Glossary “crossfire injection” Definition:
Type of throttle-body injection system that uses two injectors mounted on the manifold. Each injector feeds cylinders on the opposite side by using a crossover port.
crossflow head
Glossary “crossflow head” Definition:
Cylinder head design, having its intake ports on one side and the exhaust ports on the other side.
cross fire induction
Glossary “cross fire induction” Definition:
When one spark plug firing induces a spark into a near by spark plug wire, causing it to fire at the wrong time.
cross groove joint
Glossary “cross groove joint” Definition:
A disc-shaped, inner, constant-velocity universal joint that bolts to a transaxle stub flange and uses balls and V-shaped grooves on the inner and outer races to accommodate the plunging motion of the half-shaft.

crossfire
Glossary “crossfire” Definition:
Electromagnetic-induction spark that can be transmitted in another wire close to the wire carrying the current.
cross fluid contamination
Glossary “cross fluid contamination” Definition:
When oil and coolant are interchanged with each other. Incorrect fluid added to a system.
cross fire
Glossary “cross fire” Definition:
