Engine Coolant

[ford]

How often does a engine coolant should be changed in the car? How to check whether the coolant should be changed or not?

 

[fictious]

Depends on the life of the coolant you have installed. I dont know how to check it sorry about it.

If your car heats up soon like every 20 minutes or like that then its time to change the coolant.

There is always a pressure meter in the driving section. Usually only during long drive only the meter shows engine heat. But if it shows frequently it may be due to coolant.

I dont have much knowledge on this but the coolant work is to cool the engine i guess and so if it fails, change the coolant.

Check with a service center if you feel that the coolant need to be changed.
That would solve the problem.

Coolant reservior..

Just opened one up...
To operate properly, doesn't a coolant reservoir need to dump/draw from the bottom of the tank?This reservoir dumps the expanding coolant into the top of the reservoir.When the system cools down, it's going to draw air (not coolant) back into my radiator... sort of defeating the whole purpose of this tank.

I can't mount it upside-down, it has a vented cap.

Am I missing something? Is my tank defective? Seems like it should have a tube (inside the tank) leading from the inlet nipple down to (near) the bottom of the reservoir.

That sounds weird, jansengeorge! Usually the extra reservoir does have tubes going both ways.

As for *changing* coolant, my understanding is that, while coolant may need to be added occasionally, it generally doesn't need to be *changed* because it does not become contaminated.
