Particularly during hot months or intensive work cycles, the engines of bulldozers, cranes, and excavators can overheat. Overheating ultimately leads to engine failure and massive costs. ### Top 5 Reasons: 1. **Low coolant (Antifreeze) levels:** If there is a leak, coolant runs low, increasing temperature. 2. **Clogged radiators:** Dust and mud from the environment get trapped in radiator fins. 3. **Faulty thermostat:** A broken thermostat prevents the coolant from circulating through the engine block. 4. **Poor quality engine oil:** Oil minimizes friction. Worn-out oil raises engine friction and heat. 5. **Broken water pump:** Without a functional pump moving the coolant, an overheated system is unavoidable. Keep your machines safe by consulting us for high-quality engine components and antifreezes.
