Never open or inspect the radiator while the engine is running or the system is hot
Personal injury can result from hot, pressurized coolant. Always shut off the engine and allow the radiator to cool before examining the system or beginning any work.
Keep coolant fresh
It’s estimated that 40%-60% of engine failures are coolant related. These failures either are related to using an improper coolant or to topping off the system with the wrong product. Keep careful records to make sure you’re changing the fluid at factory recommended intervals and not mixing coolants.
Remove blockages daily
Check your radiator screen daily during warm weather for dirt, grass or other debris. A clear screen will help your machine stay cool and assure maximized performance.
Clean radiator cores
Use compressed air to blow debris from the cores. If material remains, you can use high pressure water or steam to remove dust and debris, but compressed air is preferred.
Inspect the radiator cap for damage
When the radiator is cool, slowly remove the radiator cap to reduce system pressure. Inspect the cap for damage or deposits of material. If any cracks or damage are visible, install a new cap. Otherwise, clean and close the cap firmly.
Be especially vigilant when using hydraulic attachments
Hydraulic attachments put more stress on a machine’s cooling system than using a bucket. This stress leads to faster overheating and requires the operator to keep a close watch of the machine, especially in hot weather.
