Disadvantages of the Mazda KL-DE engine
- With reliability, the engines of this series are all right;
- The aluminum block here is very afraid of overheating, watch the cooling system;
- Valve cover gaskets to 100,000 km often lose their tightness and leak;
- The timing belt serves approximately 80 – 90 thousand km, but when it breaks, the valve does not bend;
- Due to poor-quality lubrication, hydraulic lifters can knock even up to 50,000 km.
