Why does the engine overheat when idling and cool down when running hard or uphill?
Defective cooling fan or bad fan relay.
Why does a car blow cool air while idling?
Blowing cool air while idling & the water pump is not moving very fast is a key indicator of low engine coolant levels. Add some anti-freeze/water and likely you'll have warm air all the time.
Why does the engine cooling fan run on high speed after engine has been idling?
because when car is sitting still and at idle you do not have "air flow" coming into radiator to help cool it as you do when you are driving. So fan compensates for this higher engine - antifreeze temperature to try and cool it off it has to work harder.
What is the green truck from Real Steel?
MODEL: a GREEN FORD F150i think the question was asking about the transport truck. it was a 1963 international harvester cab over engine or (COE) the larger model had those windows in the grill for safteyif your looking for a cool ride to fix up thats not a great choice. check out the IH 150 metro its a cool little cargo van
How long should a diesel engine warm-up before driving?
Usually you would let it warm up to 160 degrees f, and if run hard let the turbos cool down for at least 1 minute. My truck has a Cummins ISX in it. I warm the engine up by dumping the air out of the tanks before starting the engine, and letting it build pressure by idling. When the air is up to 110psi or so, it's ready. In shutdown, if you come off the interstate and pull into a truck stop, by the time you get to where you want to stop the truck, the turbo is spooled down. If I had something like a Cat 3406 or a Cummins Big Cam--an old tech engine--in my truck I'd idle for five minutes, but the ISX is designed to be shut down quickly.
Getting stuck in the snow engine overheating?
Getting stuck in the snow and having your engine overheat is a very bad idea. You should turn the car off, let the engine cool, and call for a tow truck.
What direction does an F150 Radiator Fan operate non electric on a 1994 F-150 Ford pickup truck with a straight 6 cylinder engine?
The purpose for the fan is to cool the radiator, therefore, the blades would, by definition, turn TOWARD the direction that the part of the blade that is closest to the engine... Therefore, it would push the air toward the radiator, particularly, when the truck is not in operation. As the previous poster indicated, it is generally clockwise.
When did people start idling their cars?
Idling cars started before the Ford Model T in 1909. In those days cars were very dificult to start so once you hasd them running you didn't shut them off untill you were done with them. Now we Idle to warm or cool our cars. Blame the guy who invented the car heater.
What makes a 1981 Nissan 280zx run smooth cool but when it warms up idle rough?
when your running Dow the highway the engine get massive cooling from the high wind flow of road, but when its idling its just siting there with no real air flow to help cool it like on the road
Why does car heat up when idling and cool down when moving?
It is more than likely a thermostat
How can the thermostat in truck keep the heat from getting warm?
If the thermostat is stuck open, the radiator is able to cool the antifreeze faster than the engine can heat it.
Why does my 1995 impala SS run hotter when idling?
The vehicle does not have any airflow across either the engine or the radiator to cool things down like occurs when driving, if at an idle. This, coupled with a diminished flow of coolant through the engine at idle speed creates undissipated heat.
