Cylinder Block Drain Tap threads into the coolant jacket of the cylinder block, providing a controlled drain point for the engine cooling system.

Opening the tap drains coolant directly from the block during servicing, flushing or before frost protection, working alongside the radiator drain to empty the system fully. Fitted to the V8 EFI petrol engine.

Frequently asked questions

What is the cylinder block drain tap used for?

The cylinder block drain tap threads into the coolant jacket of the V8 EFI petrol cylinder block and gives a controlled drain point for the cooling system. Opening it lets coolant run straight out of the block during servicing or flushing.

Why drain from the block as well as the radiator?

Draining from the block clears coolant the radiator tap leaves behind, since a lot sits trapped in the engine. Using both drains together empties the system far more fully, which matters before flushing or when setting up frost protection.

When would the drain tap itself need replacing?

The drain tap typically needs replacing when it corrodes, seizes shut, or no longer seals once closed, leaving a coolant weep at the thread. Old coolant left in the block is the usual cause, so it's worth checking the tap whenever the system is drained.
