Anyone tried pumping cold water through the heater core on a non-A/C car as an alternative to A/C? Answered
My idea is that during the summer months, the heater core could be bypassed of hot coolant with a section of copper pipe. With a cooler in the trunk filled with ice-water, containing a 12V pump/sump set-up, cold water could then be ran through the heater core. If the core is cold, and air is being pushed through it, the air would thus be cooled off before being pushed through the factory vents. The fist of only two issues I can see, is that the blown air may be hot air from the engine bay, thus harder to cool off. However, my vehicle has a feature that 'recycles' the air from inside my cabin as apposed to bringing in outside air. This might rule out the concern of cooling hot air. The second issue would be the possibility that the material which the heater core is comprised (probably aluminum) and/or its seams/welds may not hold up under such cold conditions, as it is designed for hot coolant to pass through. However, cars have cold coolant for several minutes on start-up in the winter, and many people crank the heater long before the coolant is warm, thus the core probably could withstand the cold exposure. I've never asked a question on here before. I'm not sure what I hope o gain from doing so. But if you have tried this or just have 2 cents to add... please, share. Thanks.
