I need to fill/bleed my coolant and know my car is missing the bleed service kit.

Don't have access to car right now to check.

Can anyone confirm the internal diameter of the tube.

I think from past experience with other mk1's I've had, it's standard 5mm that you use for brake bleeding.

Know can use smaller one and heat it to fit nipple but as ebay do any mm width may as well buy the right one.
