A cooling system with a 17 psi radiator cap will have what boiling factor? - ANS-263° F
A refrigerant system this is as little as three ounces low can reason oil stream inside the A/C
system to decrease with the aid of as a lot as: - ANS-zero.Eight
A ruptured desiccant bag in a receiver-drier, or accumulator-drier, is usually because of what? -
ANS-Moisture contamination
An internal engine coolant leak may be due to all of the following EXCEPT: - ANS-Leaking
heater core
An orifice tube limit is regularly indicated with the aid of: - ANS-Low gauge strain
At what temperature does an engine run cleanest with least wear? - ANS-two hundred°F
By what yr did all evolved countries agree to section out production of most ozone-depleting
CFCs? - ANS-1995
During an HVAC diagnostic, which of those does no longer want to be done before checking
excessive and coffee pressures? - ANS-Identify refrigerant
Every A/C system has all the following additives EXCEPT: - ANS-Expansion Valve
How is a Hybrid A/C machine specific from conventional systems? - ANS-Its compressor is
electric
How is the Air Delivery temperature controlled at some point of A/C operation? - ANS-By
controlling how a good deal air passes over the heater center
If the ambient temperature is eighty°F, approximately what must the static A/C pressure be on
the excessive and low gauges? - ANS-80 psi
In addition to terrible cooling, what other predominant problem is related to a low rate? -
ANS-Compressor oil hunger
In an A/C machine, the low facet may have: - ANS-Larger pipes and hoses than the high facet
In an A/C system,the high side provider port may be placed in all of these EXCEPT: -
ANS-Between the evaporator and compressor
