This link has a diagram showing the location of the relay: http://autorepair.about.com/library/faqs/bl581g.htm

The Pulse Width Modulated (PWM) radiator cooling fan relay is located behind the front bumper fascia below the right head lamp.

Trace the fan wiring back from the fan--it should lead to the relay (a solid state device) that is probably mounted on the driver side radiator surround sheet metal. Clean the surface under the relay before mounting the new one. If replacing the relay doesn't fix the problem, the computer controls the relay with a signal that is generated by the coolant temperature sensor. The sensor also controls the water temperature gauge through the computer.

Um having a Mazda Axela, 2004 model (Right hand drive) 2300cc. Problem is sometimes the coolant is getting less.


have a compression test done to check for head gasket and cracks. have a pressure test done on the coolant system to check for leaks. Check the drain hole under the water pump as it may be leaking from a bad pump shaft seal . If you have a viscous fan hub then check the operation as they have been known to spin but draw sufficient air through the radiator to cool the coolant.. If it overheats predominantly at stop lights or when idling then replace the fan hub.

Radiator fluids came pouring out directly from the radiator, what


You cannot loose coolant only from the radiator without the entire system becoming low. So, lets just say that you lost coolant. You did not mention if the temp gauge was reading high.
Coolant loss is caused by either a thermostat going bad, causing an overheat that will push antifreeze out of the overflow. If you saw it leaking, you should have looked and noted the exact location of the source. (easier to fix when you know what leaked). A second source of overheat and loss is the water pump. The shaft seal when beginning to fail can sometimes leak and other times the system pressure can keep it pushed against the shaft with enough force to temporarily keep it from leaking. Most times you will see a stain or drip from behind the pump pulley, especially with a full system with the radiator cap removed (cold). You also need to check the electric fan. Sometimes the relay can become unreliable and not trigger the fan to come on when it needs to. When the engine is hot, watch the fan and check to see if it comes on as it is supposed to (sometimes covering the grille with a blanket will
make it come on faster so you don't have to spend the day watching it.
If you have any white smoke from the tailpipe, coolant in the engine oil or engine oil in the radiator, that indicates a blown head gasket. If you suspect a blown gasket, do not drive it or run it as you can severely damage the engine. If you can't find anything, have a shop check it out. they can do a pressure test, dye test and cooling system hydrocarbon test to determine what the problem is. Shops are not inexpensive but neither is an engine. Aside from all else I mentioned, check all your hoses and hose connections and correct whatever you find.
Good luck
