Hey my mx3 is overheating.. and theirs no heat coming in the car and the coolant isnt low. the coolant is topped up and never goes down. so.. and the coolant came out of the over flow tank once it really got hot. its the v6 motor i have in it.. please help! lol

Change your thermostat. Ensure that your radiator fan is running at idle. See if your heat blows warm or not when the engine is warmed. if the heat is clod, then you have no water circulation in your engine. either the thermostat isnt opening up, or there is a blockage in your cooling system.
Overheating can seriously damage a car's engine if left unchecked. Although overheating simply means that a car's engine temperature exceeds normal operating temperatures, the causes of overheating are varied. What follows is a brief list of some of the most common causes of engine overheating.
A car that overheats will often have a faulty radiator. A radiator is responsible for cooling hot engine coolant that picks up heat from inside a car's running engine. A radiator "radiates" the heat from engine coolant out into the outside air. A faulty radiator loses its "radiating" effects and allows engine coolant to become overheated, thus rendering it ineffective at adequately cooling and engine.
Faulty Water Pump
A faulty or malfunctioning water pump prevents adequate engine coolant flow and can cause a car to overheat. A water pump serves to pressurize and propel engine coolant throughout a car's engine and radiator to increase the heat-reducing capabilities of engine coolant. A faulty water pump loses its ability to adequately pump and propel engine coolant, and can cause a car to overheat.
Coolant System Leaks
A leaky engine coolant system reduces the level of circulating engine coolant, which increases engine temperature and leads to engine overheating. Radiators, water pumps, and coolant system hoses and seals--all of these coolant system parts can develop leaks, which can result in low coolant levels and engine overheating.
A car thermostat regulates the flow of engine coolant. A thermostat is a heat-sensitive valve that opens when a car engine reaches a set operating temperature and closes when a car engine is cold and warming up. If a thermostat gets stuck in the closed position, coolant will be prevented from reaching the engine, which will quickly lead to engine overheating and potential engine damage.
Low Engine Oil Level
Engine oil, in addition to lubricating an engine's internal parts, helps to keep engine operating temperatures reduced by eliminating friction within the engine. If engine oil levels are low, friction and heat build up inside an engine, a condition that causes increased engine operating temperatures and can lead to engine overheating.
Ok this one is kind of hard to diagnose but maybe I can give you some answers. The 2 problems you have work hand in hand. If you have low oil level the heat in your cylinder walls raises because there is not enough oil to lubricate the fiction caused by the pistons going up and down. Secondly if your car overheats it gets so hot that the oil gets really thin thus viscosity break down occurs. Your Honda has an electric fan on the radiator and if this fan is not working your car will overheat. Crank your car with the hood up and let it idle till the temperature gauge comes up and the electric fan should come on. You will be able to hear and see this happen. If the temperature guage keeps climbing and the fan has not come on then turn your AC on and see if the fan comes on. They are tied together and when the AC is on the cooling fan switch is bypassed and runs all the time. You also have a oil pump in your engine that keeps the oil pressure moving inside the engine. If this is going out it will cause the oil light to come on and make your engine overheat. I am sure you have checked the oil level and the coolant level in your car but if you haven't please do that. I hope this helps you out to find your problem. Oh yea if the coolant fan comes on when the AC is turned on then you have a bad sensor and you need to replace that. In any case I would not drive it until you figure this out because it will for sure cause engine damage. Good luck, Roger
