Hi, does anyone know the internal diameter of the top radiator hose on a classic import STI? Car is a 1998 V4 is that is relevant - no access to the car just now but need a water temperature adaptor.
Used search but couldn't find anything.

Thanks in advance

38mm internal diameter. You'd be well advised to buy a new top hose to do the job...I didn't, and manipulating mine split it, so it leaked the next day

Superb, thanks for that
Think the guys at GI Motorsport have it all in hand.
