Does Steel Seal Actually Work? A Test on a 2017 Mini Cooper S

TLDRIn this video, we test the effectiveness of Steel Seal in fixing a blown head gasket on a 2017 Mini Cooper S. Despite following the instructions, the product did not successfully seal the leak.

Key insights

Steel Seal did not fix the blown head gasket on the Mini Cooper S.

The instructions provided by Steel Seal were followed accurately.

The cooling system in the Mini Cooper S continued to pressurize even after using Steel Seal.

The smoke and bubbling in the cooling system persist, indicating a persistent issue.

Further examination of the head gasket is required to diagnose the problem.

Q&A

Did Steel Seal fix the blown head gasket?

No, despite following the instructions, Steel Seal did not successfully seal the leak in the Mini Cooper S.

Why did the cooling system continue to pressurize after using Steel Seal?

While Steel Seal is designed to fix leaks, it may not be effective in cases of extreme pressurization. Disconnecting the cylinder causing the pressure is recommended but was not performed in this test.

What is causing the smoke and bubbling in the cooling system?

The persistent smoke and bubbling in the cooling system indicate a persistent issue, potentially related to a blown head gasket or another underlying problem.

What further steps are needed to diagnose the problem?

The head gasket of the Mini Cooper S will need to be examined to determine the exact cause of the issue and necessary repairs.

Can Steel Seal be used with all antifreeze types?

Steel Seal is only compatible with blue antifreeze and is not designed for use with waterless coolants or extended life antifreeze.
