Kernplug - Expansieopening Cilinderblok is een geperst stalen afdichtingsplug die in de buitenkant van het cilinderblok is geïnstalleerd om de gietopeningen die tijdens de motorproductie zijn gevormd, af te sluiten.

Deze openingen ontstaan als onderdeel van het zandgietproces en moeten worden afgedicht om koelvloeistof in de interne watermantel van het blok te houden. De plug zit in een machinaal bewerkte boring in de cilinderblokwand en wordt erin gedrukt om een strakke perspassing te vormen. Vervanging is nodig wanneer corrosie, vorstschade of lekkende koelvloeistof aangeeft dat de plug defect is of uit zijn boring begint te komen.

Frequently asked questions

What is the ETC4529 core plug and what does it do?

The ETC4529 core plug is a pressed-steel sealing plug that closes the casting apertures in the cylinder block on Land Rover 2.5L engines. These openings are left by the sand-casting process and must be sealed to contain coolant in the block's water jacket. The plug is driven into a machined bore to form a tight interference fit.

Where does the core plug sit on the engine?

The core plug sits in the outer face of the cylinder block on the 2.5L engine, sealing the expansion ports along the block wall. It closes the openings into the internal water jacket as part of the engine's coolant containment. This is a Genuine Land Rover part, ETC4529.

Why do core plugs fail?

Core plugs typically fail from internal corrosion, coolant weeping, or freeze damage when antifreeze is weak and coolant expands. On these Land Rover 2.5L blocks, a plug that's rusted or pushing out of its bore needs replacing. Signs include coolant seeping around the plug or a slow, unexplained coolant loss.

How do I confirm this core plug fits my vehicle?

This Genuine core plug fits the 2.5L cylinder block on the Defender (1987-2006), Discovery 1 (200TDi, to VIN LA081991) and Range Rover Classic (1992-1994, 200TDi from JA610294). Use your VIN and engine type to confirm, as the Discovery and Range Rover fitment has specific VIN limits.
