1. What is the composition of an engine coolant without antifreeze for large engines?
An engine coolant, also commonly referred to as coolant, consists of additives (inhibitors) and water.
2. What are additives and inhibitors, and what is their function?
These are chemical stabilizers and inhibitors that, for example, maintain the pH level within a specified range and inhibit the physical corrosion of metallic materials.
3. Can I run my engine on water?
No, using plain water would cause the engine cooling system to corrode, become clogged with sludge, and develop scale. This could lead to malfunctions or even serious damage.
4. When can engine coolant without antifreeze be used?
In regions with a mild climate or in buildings where temperatures do not drop below freezing.
5. How often should coolant without antifreeze be changed in large engines?
This depends on the type of coolant and the operating conditions. It is generally recommended to change the coolant every 2–5 years or according to the manufacturer’s specific guidelines. Our coolant analyses provide a good indication of how much longer the coolant can be used.
6. What are the consequences of not changing coolant without antifreeze on a regular basis?
Old or degraded coolant can lose its effectiveness, which can lead to overheating and corrosion. This can significantly reduce the engine’s lifespan and performance.
7. What signs indicate that the coolant needs to be replaced because it lacks antifreeze?
Check the pH level regularly. If it falls below 7.5, that’s a bad sign. If the coolant contains rust particles or magnetite, is cloudy or discolored, or has an unpleasant, acrid odor, or if the engine shuts down due to overheating, these are signs that the coolant is worn out.
