Sealey Damaged Glow Plug & Heater Element Removal Set - 8 & 10mm

This set is specifically designed for diesel glow plugs and heater elements. It is not intended for use on petrol engines.

You will need a drill, drill bits (as specified or included in the set), a tap wrench, and potentially a penetrating oil and a small hammer. A torque wrench might be useful for reinstallation of new glow plugs.

Drilling too deep can damage the cylinder head or enter the combustion chamber. It is crucial to use the centring guides and drill only to the depth required to engage the tap properly.

Flush the threaded hole with a suitable solvent or compressed air to remove any metal shavings before inserting the extraction adaptor.

Please refer to Sealey's official warranty information for specific details, typically found in the product manual or on their website.

While designed for broken elements, extreme seizure may require additional techniques or professional assistance. The kit provides the best method for extracting broken pieces but relies on the seized element eventually releasing.

Ensure the centring guide is firmly seated against the cylinder head and the drill bit is inserted correctly into the guide. Use a slow drill speed.

Ensure the drilled hole is clean and the correct size for the tap. Use a cutting fluid or lubricant. Back the tap out periodically to clear debris.

Verify the thread created by the tap is clean and of the correct size. Ensure the adaptor is fully engaged with the tapped thread. Apply steady, even pressure during extraction.

Try applying a penetrating oil around the area and allow it to soak. Gently tap the extraction adaptor with a small hammer to help break any seized connections. Work the element back and forth slowly.
