MC18 Cylinder Head Coolant System link pipe

Tue May 05, 2020 4:37 pm » Post: #1 » Download Post

Hi All,

I have had my cylinder on my 1989 MC18 R5K replated.

Unfortunately the insert for the coolant system has been lost by the workshop.

Struggling to find this item seperately and may have to have one fabricated.

Wondering if anyone may have this item to give some dimensions and whether there are any O rings required.

I have attached an image to clarify as a little difficult to describe.

You're looking at about 15.5mm OD (13mm ID), overall length approx. 27mm, fitted approx. 20mm proud of the boss face.

The OEM spigot is a press fit, with a little sealant; no O-ring.

Something similar to this should see you OK.
