Heating AC and Engine Cooling
Heating, air conditioning (AC) and engine cooling require a radiator to transfer heat. Heating a cabin requires heat to be transferred from an engine block. Engine cooling blows the heat out of the engine. AC uses refrigerants to cool air.

Where can one purchase a cooling fan?
There are many places a person could go to purchase a cooling fan for their computer. Some of the best stores are Walmart, Future Shop, Amazon, eBay and Target.
What is meant by sensible heat factor?
Sensible Heat Ratio - SHR - is defined as the sensible heat or cooling load divided by the total heat or cooling load.
Try backflushing the heater core. You have two heater hoses going into the firewall - after running, one should be hot to the touch, and one should not. The one that's hot to the touch will be the inlet... when you backflush it, you'll use it as the outlet. Disconnect the heater hoses, keep the ends elevated, put in some radiator flush or CLR, and let it sit for about 15 minutes. Then, using the outlet hose as the inlet and vice versa, you can either flush it out with pressurized air or pressurized water.
How do you put an orifice tube in a 99 gmc 1500 savanna van?
To replace the orifice tube in a 1999 GMC 1500 Savanna van, first ensure the AC system is fully discharged to avoid refrigerant exposure. Locate the orifice tube, which is typically found in the liquid line between the condenser and the evaporator. Remove the necessary components to access the tube, then use a pair of pliers or a special tool to pull the old orifice tube out. Insert the new orifice tube into the same location, reassemble the components, and recharge the AC system with refrigerant.
I think I know who your talking about. Yeah, she's great!
What causes high amps in a air conditioner compressor?
your condensor is clogged up, or your condensor fanmotor is not working, or your compressor struckup due mechanical problem inside of your compressor.
Where is cabin filter in 1995 Chevrolet truck?
The cabin filter is underneath the dashboard behind the glove box, if so equipped.
Does removing thermostat in a 4G15 engine helps cool the engine?
from what im experiencing right now...i still have have a lot of work to fine tune my 4g15 piston carburetor for my 1995 1.5 wira...okay now the answer is yes...it helps better cooling but...the heat up from cold start will confuse the auto choke...it takes forever for you to heat up in the morning plus...chances are black smoke and poor idling will occur...and will lead to future problems....best to keep the thermostat....you can buy a lower thermostat valves in the after market shops...maybe something around 72'c should be fine because OEM is 82'c...dont forget that the carburetor also plays a major part in this process...too lean will heat the engine and too rich will cool the engine..if too rich you will get black smoke and unsteady idle...if too lean..a very hot exhaust air blows out means you will lost peak power and damaging the spark plug....email me if any of you have a questions about this engine at kutan_86@yahoo.com
How many types of cooling systems in an engine?
what are the types of engine cooling systems and what are the advantage and disadvantages pdf
Do you need to install a new accumulator when you install a new car AC compressor?
It is usually required for the warranty to be valid.
How pour oil in rotary ac compressor?
You do not pour oil into an ac compressor, It goes in just like the "freon",,,under pressure. You can but an oil charge kit from any good auto parts store but only use it if you absolutely know it needs oil. Too much will ruin the compressor and clog the separator.
What device cools a cars engine?
Hi,
The main device that cools a cars engine is the radiator, however to state that is not exactly true. Car engines run hot, and this is to increase the efficiency of the engine. The thermostat in the engine, and the temperature probe in the radiator are all set to keep the engine at a predetermined factory set temperature. The cooling fan behind the radiator will only work when the temperature of the engine goes over the predetermined temperature, to bring it back down. Notice the word temperature not cool in the explanation. Like the human body temperature is monitored.

There's some inaccuracies in the above answer. The radiator does not directly cool a car's engine - it cools the coolant which passes through it.
The whole cooling system is the "device" you're referring to. That would be the water pump, radiator, hoses, and thermostat. When the thermostat reaches a predetermined temperature, it opens up and allows coolant to flow through the motor. The most basic law of thermal dynamics is that heat always flows to a cooler object. Thus, the heat from the engine flows to the coolant in a heat exchange. The heated coolant then is cycled to the radiator, where another heat exchange takes place - this time, the heat from the coolant transfers to the air which is passing through the radiator. This is why it's important to keep air flow to the radiator (as well as the air conditioning condenser) unobstructed.
Additionally, the airflow over the motor created by the engine fan also creates a heat exchange, where heat from the engine is transferred to the cooler air flowing over the engine.
Can driving with a broken thermostat on your car eventually make your water pump go bad?
Probably not in the context you had in mind. If the thermostat is constantly open, however, it can cause the water pump to run excessively or even continuously, and that'll cause the pump to wear out faster.
Could needing freon cause the engine to run hot when the air conditioner is on?
No, that's most likely the result of low coolant, burned out coolant, or a thermostat in need of replacement. A defective water pump may also be to blame, or possibly even loose belts
As previous OP stated, but to elaborate, the condenser is located in front of most radiators, when you turn your a/c on the condenser will produce a good amount of heat, almost "preheating" the air going through the radiator. Your cooling system must be in good order to dissipate the additional heat. Also most vehicles if equipped with electric fans will have i.e. one or two cooling fans that will come on when the ecm or high pressure switch on the a/c indicates high pressure due to excessive heat in condenser (high head pressure). Also, look at condenser for bent fins, leaves or debris between condenser and radiator, proper electric fan operation and if it's a belt driven fan, some have temp operated clutches, the hotter they get the more air the fan will pull, if this fan clutch has leaked oil, it will cause this issue. Shut vehicles off HOT and look at the fan, if it keeps spinning freely and slowly comes to a stop, its shot, if it stops after a few revolutions its most likely in good shape. Year, make and model would help BUT for most part, if it runs cool until a/c is on, then you have a marginal issue, most likely fans, radiator getting plugged or possibly thermostat, however some VW and other vehicles use plastic impellers that fracture and others that impellers slip on the shaft, again - year make model helps...
