What to Do When Auto AC Not Blowing Cold Air
Whenever you've got a car AC not blowing cold air, the quickest and simplest way to remedy this will be to install a refrigerant to the system. This is what most of us would do. Some use Freon but this can be deadly especially when one hasn't got any idea what the pressure readings could be. There are times when the problem is not with the refrigerant but with other parts.
One should know the capacity of the air conditioning system before installing any refrigerant, regardless of whether you know the low and high side readings. It is a good idea to use high quality materials when buying parts for repair like the single hose or the AC charging kit. Substandard materials may lead to damage to the system. Always remember this when doing repairs if your vehicle AC isn't blowing cold air.
Vehicle AC Not Blowing Cold Air Still?
It only makes sense once you're able to see both the low and the high readings with the usage of an AC manifold gauge. Professional AC mechanics do this every time they find a vehicle AC not blowing cold air. Gauge readings are important when doing problem-fixing. Each reading, high, normal or low, is important.
If for instance the gauge reads low, what you want to do is hook the refrigerant to the yellow hose. Then open the blue knob found on the AC gauge set so the refrigerant can flow into the system. You would know that everything is all set once the proper reading is got. Your problem with car AC not blowing cold air is resolved. Once the system quickly loses its charge, then there is a need to diagnose and fix the leak.
When doing repairs after finding your car AC not blowing cold air, it's necessary to utilize the right tools for the job. These are: thermometer, AC gauge set, vacuum pump, and electronic leak detector. To service your AC system correctly, it's better to grasp the signification of gauge readings and what it means to have a unusual reading. A clear choice when repairing your AC will be to hire a pro to do the job. Your understanding won't be enough. Contact the Car AC Repair Phoenix professionals today!

GMC chevy 350 valve problem?
Bought a 1986 GMC 350
day 1 started up good - idle was rough - idle really too low, when brakes where applied, it would backfire.
(day 2) Changed oil which was really dark - oil filter too... ghanged spark plugs and wires. % 10 improvement... Engine lack power and vibrates but no more backfire.
day 4 Changed Cap and rotor - % 30 improvement -
day 5 Got the manifold gasket replaced. Same condition but silent...
day 6 Changed coil in cap ... Changed fuel filter % 60
improvement... The thing ran like new... Full power I started beliving again..Got full oil pressure 300 kpa - no valve noise
Ran 30 minutes on highway.... Valves started making noise especially on driver's side... Engine lost lots of power, and vibrates a lot... doesnt heat up to much but oil pressure seems very low.
(day 7) Start up the thing, and even when cold and choke on, oil pressure not as good as in the beginning.
What went wrong
Sound like a blown intake valve. Do a compression test and if you find a bad cylinder, do a leakdown test. A leakdown test is where you pump compressed air into the cylinder with the bad compression. You need to make sure that both valves are closed which is determined by the crank position. If the air is leaking into the intake/carburetor, then you have a bad exhaust valve. Time to pull the heads, or do an engine swap.
As for the "buy a Ford" guy, the GM blocks are the best out there. That is why almost all marine engines are GM blocks.
