Have an 84, 75K miles.
Had water pump and radiator replaced a couple weeks ago. My mechanic removed the thermostat for the summer. Engine got up 245 going up my driveway with a/c on yesterday. Fan goes on around 230.
Runs about 10-15 degrees hotter with a/c on. Was removing the thermostat a good idea?
Thanks!
The coolant moving too quickly through the engine and radiator IS NOT ONE. To suggest that it is, shows a lack of understanding of both mathematics and physics.
If the water moved through at 1 gallon per minute, or 100, it would make no difference in its ability to absorb heat in the engine or dissipate it in the radiator. I will explain with math, as it's the easiest. for the sake of simplicity, let's assume that, as it moves all the way through the cooling system, a single water molecule would spend half it's time in the engine and half it's time in the radiator. In an hour of driving, that molecule will spend a half hour in the radiator and a half hour in the engine, NO MATTER HOW FAST IT IS MOVING.
If this doesn't make sense to you, try this simple test of physics. Heat a pot of water, stick in a thermostat, or your finger, with it sitting still. Record the temperature and how quickly the thermostat achieved it, or how badly you burned your finger. Then quickly take the same pot and swirl the water so it is moving quickly in one direction in the pot and stick the thermometer or finger in again, and it will heat the thermometer, or burn your finger, exactly the same. This means that the heat transferred was the same whether the water was moving or not.
How many times have we seen 'physics' or some other 'science' applied here? More correctly: misapplied. The theory may be sound and even proven but it turns out to, 1) either not solely apply or 2) be overridden by other factors. At times, it seems some seem driven to bless the rest of us with their knowledge, however misapplied it may be.DDC5, you're not making any friends with this post. Your "hot pot" test does not contain any verifiable scientific information!
