Engine Coolant

Engine Coolant ( Coolant 30) is a specially formulated ready to use engine coolant, for both petrol and diesel engines. It contains a mixture of mono-ethylene glycol and selected chemical agents formulated to provide outstanding all round protection.

FAQs – Engine Coolant at German Mirror

Q: What is engine coolant?
Engine coolant, also known as antifreeze, is a special fluid that keeps the engine at the right temperature. It prevents overheating, freezing, and rusting so that metal components are not damaged.

Q: What types of engine coolants are available?
There are various types, such as ethylene glycol and propylene glycol-based coolants. Each type offers different protection levels and compatibility with different vehicle engines and manufacturers.

Q: Can I mix different coolants?
It is not recommended to mix different coolants, as chemical reactions may reduce performance and protection. Always use the type specified for your vehicle.

Q: How often should coolant be changed?
Follow the vehicle manufacturer’s recommendation. Generally, coolant should be changed every 2 to 5 years depending on the coolant type and driving conditions.

Q: What coolant-to-water mix should I use?
A 50/50 mix of coolant and water is usually ideal. It provides protection against freezing, overheating, and corrosion in both hot and cold climates.

Q: Can I use only water instead of coolant?
No, pure water does not contain corrosion inhibitors or antifreeze agents. It may be used temporarily in an emergency, but proper coolant must be added as soon as possible.

Q: Why do coolants come in different colours?
Coolant colours indicate different chemical formulations, but colour does not guarantee compatibility. Always check your vehicle manual or the product label before topping up or mixing.

Q: What is the best way to check the coolant level?
Check the coolant level when the engine is cold. Ensure the level is between the minimum and maximum marks on the reservoir tank.

Q: What causes coolant overheating?
Overheating can be caused by low coolant levels, leaks, clogged radiators, or improper coolant mixtures. Regular inspection helps prevent costly engine damage.

Q: Is coolant poisonous to humans and animals?
Yes, most coolants contain chemicals that are harmful if swallowed. Handle carefully, store securely, and clean up spills immediately.

Q: Can radiator stop-leak products be used?
Stop-leak products can be a temporary solution but may clog cooling passages. Professional repair and proper coolant replacement are recommended.

Q: How should old coolant be disposed of?
Never pour old coolant down drains or onto the ground. Collect it in a sealed container and take it to an authorized recycling or disposal centre.

Q: Can old coolant inhibitors be tested?
Yes, test strips or diagnostic tools can be used by mechanics to evaluate the effectiveness of corrosion inhibitors and cooling performance.

Q: Do classic vehicles need special coolant?
Yes, older vehicles often require traditional coolant types that are compatible with their engine materials. Always follow manufacturer specifications.

Q: What should I do after repairing a coolant leak?
After repair, refill with the correct coolant mixture, bleed out air bubbles, run the engine to normal temperature, and recheck the coolant level and for leaks.
