Product Information
Full details
Holts Antifreeze Coolant is an essential maintenance solution for vehicle owners looking for long-term engine protection and thermal management. Ideal for both petrol and diesel engines, this ready-to-use OAT (Organic Acid Technology) formula delivers high-level anti-corrosion benefits and a lifespan of up to 10 years or 300,000 miles. While it offers premium protection and convenience, users must ensure their cooling system is thoroughly flushed before application to avoid mixing incompatible chemical bases.

FAQs
Do I need to add water to this coolant?
No, this is a ready-to-use formula. Adding water will dilute the protective properties.
Can I use this in my older vehicle?
It is compatible with most Ethylene Glycol based systems, but please check your manual to ensure OAT is recommended for your specific engine type.
Is this safe for aluminum engines?
Yes, the advanced anti-corrosion formula is designed to be safe for modern aluminum engine blocks and radiators.
How often should I change this coolant?
The formula is designed to last up to 10 years or 300,000 miles, whichever comes first.
What should I do if I spill some on my driveway?
Clean it up immediately with an absorbent material. Antifreeze is hazardous to animals, so ensure the area is rinsed thoroughly.
Troubleshooting
Engine temperature needle remains high after refilling
Air locks in the system are common after a flush. Ensure the system is properly bled following your vehicle manufacturer's instructions.
Coolant level drops shortly after filling
This is often due to air bubbles escaping. Check for leaks, then top up to the 'Max' line once the engine has completely cooled.

Setup, Compatibility & Care
To ensure peak performance, follow these guidelines for setup and care:
- Compatibility Check: Verify your vehicle owner's manual to ensure it supports OAT or Ethylene Glycol based coolants. This product is ideal for vehicles requiring MB 326.0 or BMW GS 9400 standards.
- System Flushing: Do not top up over old, depleted coolant. Drain the cooling system entirely and flush with water to ensure the new OAT formula is not contaminated by old inhibitors.
- Application: Use the included pouring spout to fill the expansion tank to the 'Max' indicator. Do not overfill.
- Storage: Keep the container tightly sealed in a cool, dry place away from direct sunlight. Ensure it is stored out of reach of children and pets, as antifreeze is toxic if ingested.
- Disposal: Always dispose of old engine coolant at an authorized recycling facility or local council waste site.
