close system
The radiator should be analyzed as an open system since mass is crossing the boundaries of the system.
car radiator is an open system...because hot water is coming in and rejecting heat..this means mass and energy r flowing in and out from the system..it is a control volume through which mass is flowing..
A "closed loop" system refers to a system that requires no outside intervention. Like the cooling system on a car or in simpler terms the radiator. The cooling system is a closed loop, the coolant is heated by the engine, pumped into the radiator where it cools off, then is cycled through the engine again.
All I do is remove the radiator cap (wait until car is cold and open cap slowly) and start the car. let it warm up. the thermostat will open and begin fully circulting the coolant. if there is any air bubbles in the system they should work theirselves out. another thing to do after the thermostat opens is slowly squeeze on the lower radiator hose, careful not to spew coolant out of the radiator.
when the enjine was turnoff sometime and then open the radiator and fill it
The Radiator Drain Plug is on the bottom of the front of the car close to the left wheel. The drain plug is red and all you do is turn the plug with your hand counter-clockwise to open it.
Open the radiator cap when the engine is cool, check the radiator's fluid level, and add appropriately. NEVER OPEN A RADIATOR CAP WHEN THE ENGINE IS HOT OR OVERHEATING. Check your car's owner's manual for specific details.
Just flushing the radiator, no but to flush the system, yes.
Off, with a cold engine.
While the radiator and main hoses are generally near the front of the car, that is only a part of the car's cooling system. Included in that system are the heater lines and heater core. Look for smaller diameter hoses (about 3/4 to an inch in diameter) leading back to the firewall of your car, and inspect them for leaks. Hope this helps!
I check radiator fan, and relays and they are good, what can be a problem when my car reaches temperature to open termostat radiator fan does not work
Open the 12mm nut on the the top of the t-stat housing and pour radiator fluid in with heater set on high until you see fluid coming out of the of the bleeder nut. Close the bleeder nut and put the radiator cap back on, start the car and your done!
