Having problems with your 1998 Ford Contour ?
Air lock in cooling system, what do i do . the thermostat is good, it does not need flushing.
The best way to do it is, in my opinion, usually to start from the beginning. Get a bucket that is small enough to fit under where the radiator is. Then, open the drain **** at the bottom of the radiator, make sure the bucket catches as much fluid as it can. Dump it in a bigger bucket as a holding pen that is just as clean. Take off the upper and lower radiator hoses, drain them into the bucket. Do the same for the heater hoses. Now, put all the hoses back on. Mix the new coolant (It's always better to start with new, anyway, it'll make sure all is good) with some distilled water (swish the water around in a small bucket for a bit), to the blend the manufactorer says, or a 50/50 mix. Pour it in until about 3" from reaching the top. Start the engine, don't rev, just let it idle. keep topping up until ~3" from the top. As the thermostat opens, water will start pouring back into the radiator. Now, in 1/2" inch per 20 second increments, pour more in until it's topped up. Make sure that it's fully filled, then fill up the coolant reservour, and you are done. I just find it best to fix the problem fully, not just try and find the bubbles, you can't tell if you have one or a whole bunch.
