Shell Coolant
Though the cooling system is often overlooked, malfunctions are a common cause of engine failure. A high-quality coolant can help you avoid these, along with stressful downtime and costly repairs.
Why is coolant so important?
Whether your priority is to keep fuel costs low or emissions to a minimum, keeping your car in top condition can be one of the best ways to meet your goals. Alongside engine oils and transmission fluids, the coolant you choose can have a big say in the performance of your engine, by helping to:
- Transfer heat away from your engine, regulating engine temperature and maximising engine performance
- Protect your cooling system from corrosion, scaling or deposits, and the long-term damage they can cause
- Maintain consistent performance over the lifetime of your vehicle, so you can run your car for longer
Using a low-quality coolant can cause your cooling system to rust or your engine to overheat – both of which can risk your safety on the road or your finances in the workshop.


Why choose a Shell coolant?
As the world’s number-one lubricant supplier for 15 years running, Shell has a long history of engine fluid expertise to rely on1.
Our technology leadership has seen us build strong relationships with global manufacturers including BMW, Hyundai and Volkswagen, developing high-quality coolant that exceeds the most stringent performance requirements of modern engines – from passenger cars to heavy-duty machinery.
Four reasons to use Shell coolant

1. Enhanced heat transfer
Overheating can cause components and oil to deteriorate, exposing your vehicle to serious damage. By using Shell Coolant with Organic Additive Technology (OAT), you can prevent your radiator from overheating, keeping your car on the road and out of the workshop.

2. Excellent corrosion protection
The heat, pressure and water that your car is exposed to creates the perfect conditions for corrosion. But because the corrosion protection of Shell Coolant is only provided where it’s needed most, important anti-corrosion additives are depleted much more slowly than in conventional coolant – providing ongoing protection that meets or exceeds industry standards and manufacturer specifications2.

3. Long service life
While conventional coolant sees its anti-corrosion properties reduced after a limited distance, Shell Coolant can retain these properties for five years or 250,000 km in the case of passenger vehicles. That means you can spend less money on maintenance and less time on topping up, while potentially keeping your car running for longer.

4. Superior deposit protection
If your coolant is mixed with hard water, the high mineral content can cause scale deposits to form on the hottest parts of your engine 3. Left unchecked, this can lead to inefficient heat transfer, corrosion, and ultimately, engine damage. To guard against this, Shell Coolant LongLife Concentrate is compatible with hard water up to 500 ppm4, reducing the likelihood of deposits forming5.
