Any automotive air conditioning system employs four basic parts-a mechanical compressor, driven by the vehicle’s engine; an expansion valve, which is a restriction the compressor pumps against; and two heat exchangers, the evaporator and the condenser. In addition, there is the refrigerant that flows through this system.
The belt-driven compressor uses engine power to compress and circulate the refrigerant gas throughout the system. The refrigerant passes through the condenser on its way from the compressor outlet to the expansion valve. The condenser is located outside the passenger compartment, usually in front of the vehicle’s radiator. The refrigerant passes from the expansion valve to the evaporator, and after passing through the evaporator tubing, it is returned to the compressor through its inlet. The evaporator is located inside the vehicle’s passenger compartment. <read more>

How can I tell if My Car’s alternator is charging ?
There are a couple of ways you can do this. One is by using a multi-meter set to DC Volts. If the meter shows less than 13 Volts it is not charging(this is done with the engine running). Another indication is if the icon on the dash that looks like a battery illuminates then the alternator is not charging. Typically the alternator will produce 13.5 to 14.7 volts. If it does not you will need to replace the alternator. Make sure to check this after installation.

How do I turn off the Flashing Maintenance light (oil change reminder) on my Toyota Prius?
The oil change light will start flashing 4500 miles after the last reset to remind you that an oil change is coming up. Once at 5000 miles after the last reset, it stays on. If you change the oil yourself, or the dealer forgets to turn the light off, rather than taking it back to the dealer, do the following:

Question:
I have a 1995 Mazda Millenia that I need to have the CV Joints Replaced. Is there a difference between inner and outer CV joints? How much Should I expect to pay for the parts?
Answer:
There is a left and right cv axle for the vehicle. The right side on Napa lists for 54.19 reman and 87.49 new. The left side reman is 61.89 and new 114.00. The axle assemblies have the new cv joints and everything in them and are the most cost effective way to replace the cv joints. I’d say labor for both sides is 2 to 3 hrs.

Yes, fuel injectors can be cleaned to an extent. Most service stations and dealers offer a fuel injection cleaning service the uses an industrial grade solvent to run through the injectors by use of pressure and the kit installed directly to the fuel rail. This is the best cleaning service to have done but you want to make sure they use the direct cleaning kit.

Question:
My engine warning light came on and the dealer said the 2002 Acura RSX with 99,000 miles needed a $1,000 catalytic converter. I took the car to Auto Zone and they reset the engine warning light after running the diagnostic check. I have driven the car about 200 miles and the engine warning light has not come on again. How long do I need to drive it before everything resets prior to running a new emissions test?
Answer:
Typically if the check engine light was going to come back on it would have by now. Usually there is a secondary cause for converter failure i.e. engine misfire, raw fuel being dumped etc. As to running new emissions test I would have it done so long as check engine light is off. These vehicles are sensor-ed to the point that anything at all pertaining to emissions will trigger the light on.

Tighten the spark plugs to 20 N·m (15 lb ft).
