Mazda 6 Head Gasket L3G2-10-271 – Cylinder Head Gasket, Asbestos or Metal Styles

Mazda 6 Head Gasket, Part L3G2-10-271

This Mazda 6 head gasket is a replacement cylinder head gasket with part number L3G2-10-271. Easy Life Markets sells it in six styles, A to F. The supplier lists styles for the Mazda 6 (built before and after October 2005), the Mazda 3 1.6 and the Mazda 5, in either asbestos-based or metal construction. One gasket comes in each order.

A head gasket seals the joint between the engine block and the cylinder head. It keeps combustion pressure in the cylinders and stops coolant and oil from mixing. When it fails you may see white exhaust smoke, coolant loss with no visible leak, milky oil, overheating or bubbles in the coolant tank.

Important: Asbestos and Metal Styles

The supplier lists most styles of this Mazda 6 head gasket as made with asbestos, and some as metal. Please read this before ordering:

• Asbestos is a health hazard. Breathing its fibres can cause serious lung disease, including cancer. Gaskets are generally low risk while intact, but scraping, sanding, grinding or using compressed air on old or new asbestos gaskets can release fibres.
• Asbestos products are banned or restricted in many countries. It is your responsibility to check that you can legally buy, import and fit an asbestos gasket where you live.
• We recommend the metal styles wherever they fit your engine. Metal head gaskets do not carry the asbestos risk and are the modern standard.

If you are unsure which style is metal for your car, contact us before ordering and we will confirm with the supplier. You can read more about asbestos and its health risks.

Styles Listed by the Supplier

The supplier's style list is written in shorthand ("Ma 6" and "Horse 6" both mean Mazda 6) and repeats one letter. As written, it reads roughly:

• A: Mazda 6, built October 2003 to 2005
• B: Mazda 6, built after October 2005, asbestos
• C: Mazda 6, built October 2003 to 2005, asbestos
• D and E: Mazda 6, built after October 2005, metal
• E/F: Mazda 3 1.6, asbestos; Mazda 5, asbestos

Because the list is unclear, please do not rely on the letter alone. Match the part number and engine on your car, and message us with your model, year and engine size so we can confirm the correct style.

Fitting a Mazda 6 Head Gasket

Replacing a head gasket is a major job. It means removing the cylinder head, cleaning both mating surfaces, checking the head for warping, fitting the new gasket and torquing the head bolts in the correct sequence. Many engines also need new head bolts. If you are not experienced, have a qualified mechanic do it. For more on how a head gasket works and why they fail, see the overview.

When handling asbestos-based gaskets:

• Wet the old gasket before removal and scrape gently; never sand, grind or wire-brush it dry.
• Wear a properly rated respirator and disposable gloves.
• Do not use compressed air to clean the area.
• Bag old gasket material and dispose of it according to local rules for asbestos waste.
