Pinhole in coolant bleed valve

[Jamieb]

I have a 2002 Disco 2 with 153,000 miles. Today I noticed coolant spray residue on the hoses on the passenger side. Looking at the engine, this would be from the bleed valve left to the thermostat housing.

I removed the hose from the bleed valve to the thermo housing, inspected and replaced. Coolant was low about 4 quarts. I replaced coolant, bled the valve and test drove 10 minutes with engine warm.

Temp was normal. When I shut off engine, the bleed valve was wet. I noticed just below the bleed screw cap was a pinhole on the plastic with coolant seeping out.

Just wanted to be sure this hole is not part of the bleed system?

Anyone know a good place to order a replacement if needed?

Thanks!
Jamie
