I'm guessing you have air in your cooling system, you need to properly bleed your system.
remove the cap from the expansion tank, and remove the bleeder screw which is a plastic screw to the right of the expansion tank cap. the bleeder screw looks like a plus sign and is plastic. it's maybe 1/2 inch long when removed and maybe 1/2 inch wide. just look for a screw with the cross mark or plus sign and unscrew and remove it.
turn your key on, but don't start the engine, and turn your heater temperature all the way to hot, this will open up the valve to your heater core, and also turn the fan on.
now slowly start filling your expansion tank. coolant will bubble out of the bleeder screw, keep filling the expansion tank until only coolant comes out of the bleeder screw hole, no bubbles. you will spill some coolant doing this, so put a towel under the car to minimize the mess. you can also massage your coolant hoses, trying to get all the air out of your system when doing this.
close everything up, drive the car to temperature, and repeat this process until you cannot get any more coolant into the system. some people say you can raise the front end of your car to make the job easier, but I never had to do that with my car.
Good Luck Martin
