Maintenance of the Mazda 6 gh / Mazda 6 gh cooling system: replacing antifreeze


Maintenance of the Mazda 6 gh / Mazda 6 gh cooling system: replacing antifreeze

Coolant in a car engine is a very important element.
During operation, the piston group and other components of the machine heat up and require constant cooling. This is especially true for the high-revving engines of the Mazda 6. Antifreeze acts as a coolant. However, it also has its own production resource. Any coolant must be replaced on time. Replacing antifreeze in Mazda 6 cars is not done so often, but ignoring the next procedure is fraught with the most disastrous consequences, including a major engine overhaul.

Our auto repair shop provides a full range of services for repairing cooling systems and replacing any fluid, as well as examining components and assemblies of cars, including Mazda.

Signs by which you can determine that it’s time to go to a car service to replace antifreeze:


  1. Car manufacturers specifically make fluid expansion tanks transparent. The owner of the car can check the antifreeze level himself by looking at the marks on the tank body. Notches indicate changes in the volume of liquid poured. If the antifreeze level has dropped to the minimum level or below. But there are no visible leaks on the radiator or pipe, which means the antifreeze has lost its properties and thickened, it’s time to change it.

  2. Coolants come in different colors. This helps consumers remember what kind of antifreeze they filled in; if necessary, add liquid of the same color. You will have to replace the antifreeze if its color has changed at all. That is, the owner remembers that the liquid was green, but turned brown. This indicates that the antifreeze resource has been exhausted.
  3. The engine cooling fan is constantly running. Antifreeze does not cope with its duties and the engine requires additional cooling. Overheating of the internal combustion engine is dangerous for the overall performance of its components and assemblies, so if you suspect that the cooling fan is operating too often, or a high engine temperature light comes on on the instrument panel, you should immediately go to a workshop to replace the fluid.
  4. Any coolant has its own resource. Even if at first glance everything is in order, this does not mean that irreversible processes have not begun in the radiator. Antifreeze should be changed every 200 - 250 thousand kilometers, or 5 years of operation. And it doesn’t depend on whether the car was parked all this time or not.
  5. The owner of the car has changed - this is also a reason to replace all the fluids, including antifreeze. It is not known how the car was used before the new owner. Maybe the antifreeze was never changed at all.
  6. The Mazda 6 cooling system was repaired, which means that after assembly the fluid needs to be changed.
  7. The heater in the Mazda 6 does not heat well. Antifreeze not only cools the engine, but also provides heat to the car interior. Therefore, if the stove stops heating, it means the liquid has thickened and clogged the passage in the heat exchanger.

You cannot replace antifreeze with your own hands. This procedure seems simple only at first glance. There are many nuances that a simple car enthusiast does not take into account. Our service center employs only highly qualified specialists. We can offer suitable antifreeze for your Mazda 6 GH, or change the fluid that you bring with you.

Types of coolant:

  • FL 22. Green in color, considered the original liquid, poured at the factory during production. Used in Mazda 6 GH 2007 - 2012 model years.
  • G 12 and G 12+. Red color, suitable for engines that came off the assembly line from 2002 to 2007.

Replacing antifreeze Mazda 6 III, Mazda 6 II (GH), Mazda 6 I (GG)

Removing radiators for MAZDA 3, washing the cooling radiator.

Your health is more valuable than a new cooling system pipe or a tube of sealant! We check the temperature and condition of the cooling hoses, and if there is any suspicion, we replace the cap at a cost of only RUR! And this is the first point for diagnosis - I confirm.

To identify the car and reliably select the cooling system of the Mazda 6 I GG Sedan, you should carefully...

Correct leaks in the cooling system in a timely manner to prevent coolant vapors from entering the vehicle interior during operation. In this case, it can escape through leaks in connections, or cracks in the radiator or pipes. And on the advice of friends, I bought a Moskvich car with a radiator cap - incl.

Avoid inhalation of its vapors and contact with skin. If you remove the plug on an overheated engine and this action coincides with thermal shock, then boiling of the liquid and the formation of air pockets in the cooling system of the Mazda 6 cooling system will be guaranteed. Signs by which the condition of used antifreeze in a Mazda 6 is determined:

Antifreezes are distinguished by the additives they contain: If you need to add coolant to a Mazda 6, then it is safe to mix only one type of antifreeze, not a color. Color is just a dye.

It is forbidden to pour even distilled water into the radiator of a Mazda 6, since in hot weather at a temperature of about C the water will boil and scale will form. In cold weather, the water will freeze and the pipes and radiator of the Mazda 6 will simply burst.

They replace the coolant in a Mazda 6 for several reasons: The antifreeze is running out of time - the concentration of inhibitors in it decreases, heat transfer decreases; The level of antifreeze from leaks has decreased - its level in the Mazda expansion tank should remain constant.

In this case, it can escape through leaks in connections, or cracks in the radiator or pipes.

Why is it better to trust a professional to replace antifreeze on a Mazda 6 gh?


Firstly, during the replacement procedure, the Mazda 6 GH is raised on a lift, and a specialist will check the quality of the pipe connections and the tightness of the radiator itself from below.
Which is impossible in a regular garage. Express inspection of the engine compartment for leaks in the cooling system, as well as the degree of wear of the equipment. Secondly, only a car mechanic will be able to determine whether the components of the Mazda 6 GH cooling system require replacement or repair, especially if the car is older than five years. In addition, a list of spare parts to be replaced is compiled absolutely free of charge.

Thirdly, emergency situations often occur when replacing antifreeze in the garage. The most common thing is that debris or metal shavings get into the radiator. Subsequently, a foreign object blocks the passage in the tubes. This is not possible in our car service.

Fair pricing and quality guarantee


The auto repair shop's pricing policy allows it to seriously compete in the car repair and maintenance services market.

We provide a guarantee for every antifreeze replacement for Mazda 6 GH. If the liquid was purchased from our service, there is an additional warranty from the antifreeze manufacturer.

Replacing antifreeze with your own hands

Winter is coming. Anyone who has changed the antifreeze themselves, tell the kettle in detail how to change it, namely: 1. What and where to unscrew, in what sequence. Hot or cold. 2. What and how to wash, how long to wash. I heard that the first rinse is done with a special liquid (who used which?), the second with distilled water. 3. Which antifreeze can be poured and which is not necessary. I'm interested in real experience, whether all sorts of super duper sophisticated blue antifreezes, designed for 100 thousand kilometers, are suitable. 4. Where and how much to pour (into the radiator, into the expansion tank), how much goes in, and most importantly, how to bleed air from the system. I read that you need to put the car on a slope, face up, and apply gas (for how long?), another way is to dent something “on release.”

I changed it 3 years ago, upon arrival at the service station, from green to green, without flushing. We diluted it with ordinary water, so I’m waiting for sediment, and I want to rinse it thoroughly and generally do everything correctly (and preferably for a long time), so that neither my engine nor my brain warms up due to this
