Engine overheating

Four cylinder front wheel drive automatic 116,000 miles. I have been having overheating issues with my car for the past six months and no one seems to be able to figure out why. i have had my thermostat changed two times, still overheating. my radiator has been replaced, still overheating. all my hoses have been checked for leaks, the check out fine. i have had the water pump checked by two different mechanics and they both say that it is working fine. when my car overheats it blows out antifreeze from the hose that connects the overflow to the radiator... i was told that if if run my heater it will pull the heat off and keep it from running hot, but when i run my heat while driving it causes it to shoot straight up to the H. also, when my car is sitting at a red light, in a parking lot, or anywhere where the engine is on but not moving the heat will blow cold. i do not know if it is related but the issues both seem to have started at the same time. I know the top hose is hot. I have never checked the bottom hose. The cooling fans have been checked and they do work. Please help me!

Very slim. Coolant sealants in a bottle do more harm than good under most cases.

My radiator fan works fine sometimes. When I go on long trips my engine overheats and I notice the fan is not on while the car is running. But sometimes the fan kicks in. what can be the problem?

May be a sticking relay. it is the cheapest and easiest fix. your cooling fan relay is located in the under hood fuse/relay block.
