A common issue we’ve encountered with the Mazda CX-5 diesel models, particularly those exceeding 150,000 kilometres, is the failure of the original plastic water fittings under the inlet manifold. Diesel vibrations can cause these plastic fittings to fracture over time, leading to potential engine overheating and severe damage.

At Blackwood Dyno Tune & Service in Blackwood, we recommend upgrading these plastic water fittings to more durable metal versions well before 150,000km to avoid overheating, leading to catastrophic engine damage. We've successfully performed this upgrade on multiple vehicles, preventing costly engine replacements.

Our recent work on a Mazda CX-5 involved replacing the faulty plastic fitting with a robust metal piece, safeguarding the engine from future failures. Our gallery of before-and-after photos showcases the difference the original fitting and the Mazda factory upgrade.
