Full details
The Dunnet Tools 5L Antifreeze Coolant is designed for vehicle owners who need reliable year-round thermal management for their engines, vans, or motorbikes. This premium mono-ethylene glycol–based formula provides critical protection against freezing in winter temperatures as low as –26°C and prevents overheating during summer months, extending the lifespan of vital engine components; however, users must ensure the engine is completely cold before application to avoid pressure-related hazards.

FAQs
Can I mix this with other types of coolant?
It is generally recommended to flush the old fluid before adding new coolant to prevent chemical incompatibility between different additive packages.
How often should I change this coolant?
This formula provides protection for up to 2 years, after which it should be drained and replaced.
Is this product safe for aluminum radiators?
Yes, the formulation is designed to protect standard engine components, including aluminum radiators, from corrosion.
What happens if I spill the coolant on my paintwork?
Wash the area immediately with plenty of water to prevent potential damage to the vehicle's finish.
Do I need to dilute this coolant with water?
This is a ready-to-use formula; follow the pouring instructions directly into the expansion tank as directed.
What is the purpose of the bittering agent?
The bittering agent is added to give the liquid an unpleasant taste to discourage accidental ingestion by children or pets.
Troubleshooting
Coolant level drops shortly after topping up
Check for external leaks in hoses, the radiator, or the water pump, or ensure the cap is tightened securely.
Engine temperature gauge remains high
Verify that there is no air lock in the cooling system and ensure the coolant level is at the manufacturer's recommended 'MAX' mark.
Discoloration of coolant in the reservoir
This may indicate internal corrosion or contamination; consider a full system flush and replacement.

Setup, Compatibility & Care
To ensure maximum effectiveness, drain any existing old coolant from your system if it has exceeded its service life or is contaminated. Always store the container in a cool, dry place, keeping it tightly sealed to prevent evaporation or contamination. When disposing of used coolant, adhere to local environmental regulations, as it should never be poured into standard drains or soil. The coolant is compatible with most standard cooling system materials, including aluminum and cast-iron components common in modern engines.
