The CA is leaking coolant. Have circled where it is leaking in the pix. It is a dicast elbow, with a steel fitting pressed into each end. It appears the steel fitting facing the rear has rusted and has a pin hole. Area is wet, and although engine has not started for 3 weeks, have drips of coolant on the floor.

Any one come across this before. Thinking of using a plastic elbow, with some new hose ???

As assume you cant buy this fitting.

Cheers
