Komplug - een komvormige kernplug (ook wel expansieplug of welchplug genoemd) die een gietgat in het cilinderblok of de cilinderkop afdicht.

Deze wordt in de bewerkte boring gedreven en sluit de openingen die door het gietproces zijn achtergelaten af, waardoor koelvloeistof in het waterkanaal wordt vastgehouden.

Frequently asked questions

What is the Cup Plug used for?

The Cup Plug is a cup-type core plug, also called an expansion or welch plug, that seals a casting core hole in the cylinder block or head. Driven into its machined bore, it closes the openings left by casting and keeps coolant inside the water jacket.

Which Land Rover models and engines does this Cup Plug fit?

The Cup Plug fits Land Rover Defender 1987-2006 (2.25 and 2.5 petrol, 2.5 naturally aspirated and turbo diesel, 200 TDi and 300 TDi), Discovery 1 with 200 or 300 TDi, and Range Rover Classic V8 EFI petrol and TDi. Check your engine before ordering.

Why do core plugs like this fail on Land Rovers?

Core plugs like this Cup Plug typically fail by corroding through from the coolant side, then weeping or leaking coolant. They're often renewed as a set during an engine rebuild or when a leak appears, since access is easier with the engine stripped.

How is the Cup Plug fitted?

The Cup Plug is driven squarely into its machined bore with a suitable drift or socket until seated, usually with a smear of sealant. It's a straightforward job with the right drift, though plugs behind the flywheel or manifold can need more dismantling to reach.
