I would like to estimate the amount of time needed to idle a car in order to get it warm in a cold day.
I need to know how much of the coolant fluid is actually inside the engine (The car datasheet just gives you the total coolant volume such as 19 qt, but this includes the radiator and the heater) and how much weighs the engine block itself as it gets heated as well.
I need the answer for the F-150 but will appreciate a generic answer for any car (a link or something).
You could pull off the bottom hose on the radiator then measure how much comes out of it. (maybe put your hand over the opening then refill it with water first) I would take a guess on the heater then, you should be close.
But I was wondering if they actually mention it somewhere. I also need to now the size of the engine block itself. And it is not practical to do it for every car...
In the owner's manual they mention the total volume of coolant that goes into the engine, the radiator, the heater and the overflow. (e.g. 19 qt)
I am interested in the amout inside the engine only.
warm up time depends on outside temp. t-stat won't open untill set point is reached.Now does warm-up mean hot air blowing out of heater or when is it safe to leave the driveway,I idel for at least a minute the proceed slowly,as oil and other things might need time to loosen up,before I put a load on the motor.Your engine is always full of coolant once the intial air has been worked out,the heater may hold aprox.+-1.5qts. If your concern that the block may be empty it's not ,the coolant system is a closed loop and it's up to you to maintain a full level.As far as idle time,you decide according to conditions ,on these new motors the computer handles the amount of fuel given to the motor during start-up and idle as opposed to a carburator
