Location. Temperate grasslands are located north of the Tropic of Cancer (23.5 degrees North) and south of the Tropic of Capricorn (23.5 degrees South).The major temperate grasslands include the veldts of Africa, the pampas of South America, the steppes of Eurasia, and the plains of North America.limate. Temperate grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They typically have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer.
In summary, certain conditions can force a heat pump into a defrost cycle (or cooling cycle) where the fan in the outdoor coil is stopped, the indoor fan is stopped or electric heat is turned on, the frost melts and is removed from the outdoor coils.
There is a temp sensor in the engine which tells your fan when to kick on. If that is faulty, the fan won't turn on, and it will overheat when idling. If it overheats while idling, I would look at the fan to make sure it's doing it's job...when I say look at the fan, I mean check the temp sensor, check the relay, and check the fan itself.ome things you might turn to... - Low coolent level-Thermostat is stuck-A bad water pump-Faulty coolant temp sending unit-Faulty engine temp sending unit? - Faulty engine fan relay, or fan itself is bad-Radiator is plugged A faulty temp sensor and/or gauge can read high heat, but be wrong.
