Engine Coolant Replacement

Model: Mazda 3 BK, MK 1 - Years 2003-2009
Part: Antifreeze coolant

Lift the vehicle and secure it. Before proceeding, open the radiator cap. Remove the plastic cap located under the radiator using the special tool, then place a container under the vehicle to collect the used coolant. Allow all the fluid to drain completely. Close the lower cap and fill the radiator with new coolant to the level indicated on the expansion tank. Start the engine and run it until the thermostat valve opens. When the engine is cold, top up the fluid if necessary. Antifreeze is a chemical product and must not be disposed of in the environment; take it to appropriate collection and disposal centres.
