Mixing incompatible coolants often causes sludge build-up, which clogs radiators and hoses. This can quickly lead to overheating and costly repairs. Always choose a coolant that meets the engine manufacturer’s specifications. The TGP coolant is specially designed for commercial vehicles, offering the right protection against heat and corrosion.

2. Neglecting Regular Coolant Changes

Coolant does not last forever. Over time, it loses its effectiveness and breaks down. Old coolant becomes acidic and can:

Corrode engine components
Damage the radiator and hoses
Reduce cooling efficiency

Ignoring scheduled coolant changes risks overheating and engine failure. Regular replacement helps keep the system clean and working at full capacity. For heavy commercial vehicles, the coolant works hard and needs to be checked and replaced more often than in smaller vehicles.

3. Filling Coolant to Incorrect Levels

Both too much and too little coolant can cause problems.

If coolant level is too low:

Engine can overheat quickly
Cooling system loses pressure
Air pockets may form, causing hot spots

If coolant level is too high:

Pressure builds up and may cause leaks
Overflow can damage other engine parts

Always check coolant levels when the engine is cool. Use the recommended fill line and avoid guessing or topping up without measuring. The TGP coolant comes with clear instructions to maintain the correct level for optimum performance.

4. Mixing Coolant with Water in Wrong Proportions

Coolant needs to be mixed with water before use, usually in a 50:50 ratio. Using too much water or too little can reduce the coolant’s protective qualities.

Too much water causes:

Reduced boiling point, risking overheating
Increased corrosion inside the cooling system

Too little water causes:

Poor heat transfer
Risk of freezing in cold weather

Using distilled or demineralized water is also important; tap water contains minerals that cause scaling and clogging. Carefully mixing coolant and water, as advised for products like TGP coolant, ensures the engine gets the right balance of protection and cooling.
