    My engine temperature gage fluctuates while I'm driving, but the engine is NOT overheating. It can go all the way up to red, but if I keep driving, it will go back down again. It is a 2001 Civic EX. What can the problem be, and what will be the least expensive way to correct it?

    Top off the radiator and reservoir with coolant and then bleed the cooling system.

    I'll see how much my mechanic will charge to do it. I'm disabled, on a fixed income, and can't do it myself.

    It's a relatively simple procedure. Maybe a friend can do it for you.

    Is this fix to remove an air pocket in the cooling system?

    Yes. Top off with coolant in reservoir and radiator and then bleed the cooling system.

    Then go from there.

    It definitely worked. My mechanic came to clean my intake manifold, and he bled the coolant for free. My car is back to normal.

    I've learn that a pocket of air can be within. this can be fixed by just raising the car from the front and remove the radiator cap. and top of with coolant. wait for the air to come out and add more coolant. repeat the process until all the air is out.

    That's exactly what the problem was, but my mechanic did what you said, and the problem is fixed now. He came to do something else, and he added this for free. Thanks for the help!:D
