Question 1

Technician A says that a freewheeling engine is one that does not slow the vehicle down when decelerating. Technician B says that a freewheeling engine is one in which the valves cannot contact the pistons if the timing chain or belt breaks. Who is right?

Accepted Answer

A freewheeling engine is designed so that the valves do not contact the pistons if the timing chain or belt breaks, which is what Technician B describes. Technician A's statement is incorrect.

Question 2

Technician A says that an automatic transmission heat exchanger is often located within the radiator. Technician B says that an automatic transmission heat exchanger is often found in the bottom of a radiator. Who is right?

Accepted Answer

Both Technician A and Technician B are correct. The automatic transmission heat exchanger, also known as a cooler, is often located within the radiator or at the bottom of it to help dissipate heat from the transmission fluid.
