Question

A tech is testing an upper radiator hose by squeezing it. the most likely cause of cracking or crunching noises would be:

a corroded anti-collapse spring
low coolant level
a deteriorated hose inner liner
damage due to contact with power steering fluid

Answer 1

The most likely cause of cracking or crunching noises when squeezing an upper radiator hose is a corroded anti-collapse spring.

Step-by-step explanation:

When a tech is testing an upper radiator hose by squeezing it, the most likely cause of cracking or crunching noises would be a corroded anti-collapse spring. This spring is designed to prevent the hose from collapsing under suction when the engine is running, so if it is corroded or damaged, it can cause noises as the hose is squeezed. Other potential causes of cracking or crunching noises include a deteriorated hose inner liner or damage due to contact with power steering fluid.
