Oil in Coolant: What Now? Removal, Disposal and Certification

Oil in coolant

Draining coolant in oil

Oil in Coolant? This is what you need to know as a car company!

Car dealerships and garages regularly encounter vehicles where oil has spilled into the coolant. This is often a result of a broken head gasket, a leaking oil cooler or, in rare cases, a crack in the engine block. The consequences can be serious: overheating, reduced engine performance and damage to the cooling system as oil deposits in pipes and radiators. The longer a vehicle goes on with this, the greater the likelihood of costly repairs and permanent engine damage.

But besides the technical impact, there is another problem: waste management.

Hazardous Waste That Must Be Handled Properly

When oil and coolant mix, it creates waste that cannot simply be discharged. The combination of these substances makes the liquid harmful to the environment and poses risks if not disposed of properly. To do this safely and according to the law, a certified collector is necessary. Koeweit Oil Trade offers a complete solution for automotive and industrial companies, from safe storage and transportation to proper disposal. We have all the necessary permits and certifications, so you can be sure that your waste will be disposed of according to regulations. We also provide the right documentation, so you can always prove that the waste has been processed responsibly.

What should you do if you have oil in the coolant?

As soon as you notice that oil and coolant have mixed, quick action is crucial. First, have the defect investigated and repaired to prevent further damage to the engine. Next, thoroughly flush the entire cooling system to remove all oil residue. The contaminated coolant released in the process should be collected in an appropriate container and should not end up in the sewer system or in nature. Because this liquid is considered hazardous waste, it is mandatory to use a licensed collector for disposal. Koeweit Oil Trade will completely take care of this process for you. We ensure that your spent coolant is processed in a safe, environmentally friendly and legally compliant manner.

Frequently Asked Questions

Can I dispose of oil in coolant myself?

No, companies are required to have this collected by an approved collector.

Yes, oil can get into the coolant due to a defect in the engine. The most common causes are a broken head gasket, a leaking oil cooler or a crack in the engine block or cylinder head. This causes engine oil to mix with the coolant, which is harmful to the engine and cooling system.

If engine oil gets into the coolant, the coolant loses its effectiveness and the cooling system can become clogged with oil deposits. This can lead to overheating, accelerated wear of engine components and possibly permanent engine damage. In addition, disposing of the contaminated coolant becomes more complex because it is now considered hazardous waste.

As a garage or workshop, you may not discharge contaminated coolant yourself or mix it with other waste streams. This is considered hazardous waste and requires a licensed collector. Koeweit Oil Trading offers a complete disposal solution, including safe storage and certification.

Brown coolant can indicate several problems. It could mean that oil has entered the cooling system due to a faulty head gasket or oil cooler. Another possible cause is corrosion and rust in the cooling system, especially if old or improper coolant has been used. In either case, it is important to identify the cause, flush the system and replace the contaminated coolant.

We comply with all Dutch and European environmental requirements, including VIHB registration.
