1) Low sodium chloride causes Hyponatremia.(Extra cellular compartment) 2) Low potassium chloride causes Hypokalemia. (Intro cellular compartment) 3) Low calcium ions causes Hyocalcemia.(Extra cellular compartment ) 4) Low magnesium causes Hypomagnesemia. ( intro cellular compartment ) 5) Low iron causes Iron deficiency anemia. 6) Low Iodine causes Hypothyroidism. There are other trace element like Chromium,Manganese, (Iron ) Cobalt,Nickel,Copper,Zinc. (Why are they sitting in a row in periodic table ? ) and few others like molybdenum. These trace elements are integral part of various enzymes in body. (So with Sodium you have Calcium and with Potassium you have Magnesium. Please , refer there position in periodic table )

Maybe the tires? If it is in the engine compartment, it is probably either a loose belt or one is getting old and slipping.

A leak some where in the system, such as a bad head gasket, a cracked head, a leak from the radiator, a leak from the water pump.
