Frequently asked questions

What does the 602289 cup plug do?

The 602289 is a pressed-steel cup plug, or core plug, that seals the front casting gallery in the Rover V8 cylinder head. It blanks off a hole left from casting and keeps the coolant passage sealed.

How many cup plugs are fitted per cylinder head?

Typically four cup plugs are fitted per Rover V8 cylinder head. They're sold individually, so order four to renew a full set on one head while it's off for overhaul.

Which engines and models use this cup plug?

This cup plug fits the Rover V8 cylinder head on the Defender up to 2016, Series 2 and 3, Discovery 1, Discovery 2, Range Rover Classic and Range Rover P38. On the Defender the casting is also shared with the 2.5L four-cylinder diesel head.

Why would a cup plug need replacing?

A cup plug usually needs replacing when corrosion or a coolant weep shows at the front of the cylinder head. They're commonly renewed during a head overhaul on the Rover V8, since access is easy with the head off.
