For reasons we just can’t figure out the number one internet search for mobile A/C components and the number one blog post consistently read is about the function of the system’s receiver drier.
The heater control valve (sometimes called the hot water valve) is used to control the rate at which coolant flows through the heater core. The valve is located on the…
Soon temperatures will tumble, sweaters and jackets will come out and in order to be comfortable you’ll choose to turn on the heat inside your car. How does heated air get into your car?
Pressure testing is used to check for leaks in the cooling system and to test the radiator cap.
According to MACS member Spectra Premium Industries, a North American manufacturer of many aftermarket A/C and engine cooling system parts, testing for electrolysis is a simple task. Use a digital volt ohms meter (DVOM). Set your meter to DC volts. With the engine off, hook the negative lead from the meter to the negative post of the battery.
A vehicle has many electrical circuits. For an electrical component to function properly, the electricity must return to the source through the ground side of the circuit. Ground paths are usually metal conductors such as wires or the vehicle frame, engine or body.
One way to check for proper coolant circulation is to check the upper and lower radiator hoses. The upper radiator hose should be hot, around 190–200 °F. (The safest and…
Coolant of good quality will be brightly colored. As coolant becomes old, it usually turns into a brownish, rust colored liquid. At this point the coolant is past its useful life and must be changed.
With all the long-life coolants, and even the three-year/50,000 mile conventional coolants, it’s fair to ask: why do we see so many cases of coolants failing at low mileage.
A good flush and fill machine is the most practical way to get out at least 90% of the old coolant. You don’t have a machine and want to do a conventional drain and fill?
Did you know today, Tuesday, September 14, 2010 is the 40th anniversary of the United States Clean Air Act? Section 608 and Section 609 which regulate stationary and mobile…
