Your garage can get extremely hot at times, and that’s no different with your car’s air conditioner or compressor. However, in this case it can be much worse because your car is almost certainly running on a cold engine. This means that the temperature of the engine has to go up, and this would be extremely bad for any sort of cooling system. For this reason, the usual repair option is to try and cool the engine off as quickly as possible.
This can work for a car air conditioner and compressor but will not work as well for a radiator fan assembly. The radiator fan itself is made up of a big, flat rotating metal cylinder, and that rotating cylinder is surrounded by what’s called a heat exchanger. That heat exchanger is designed to move heat from the engine to the radiator, so that the engine gets cooled down faster. A lot of people think that using a fan to move the hot air from the engine to the radiator is inefficient. They are wrong. That is because it is not at all uncommon for the engine to turn off if there is a problem. But the engine only shuts down because the heat exchanger is cold.
Now, you could run both engines off of one set of water, and so it will remain at that temperature, but that is not the most efficient way to run your car. The more efficient way to go about it is to have the two different sets of engines go at different temperatures at the same time. This is achieved in most compressors and air conditioners by adding a secondary cooling system in the form of a water reservoir. This reservoir is normally used to store fluid that is filtered to remove any debris, or oil that is used to clean the system.
