good book on physics of autos? pressure in coolant system...
hi all! got a couple questions if anyone's got the time!
1) got an intermittent coolant leak that i'm trying to pin down. it seems to happen with the ventilation fan on. does turning the ventilation fan re-route coolant or change the pressure in the cooling system? does the heater valve open when the fan comes on regardless of temp setting?
2) the fan only comes on at setting 4 (the max). are the resistors and/or connections that have mostly likely fried right behind the ****?
3) since the water pump runs on the cam belt, does the pressure in the cooling system depend on RPM? so i could only leak coolant when i run hard => say above 4k rpm?
4) anyone know a good book on the basic physics of internal combustion engines and autos in general? one that has mostly "back of the envelope" calculations that are useful?
cheers and TIA!

1. WHere's the leak? I don't know, but I don't think the coolant would be re-routed when you turn on the fan.
2. Soulds like the resistor pack is fried. Its on the blower motor on my early model.
3. I think the pressure in the system depends mostly on the temperature of the collant.
