I have a coolent leak.
Have replaced the darlek cap, not the issue.
Have found leaks in pipes and repaired replaced pipes/jubilee clips but still lose coolent.
1.6td
where is the water going!!!!
How can I find out, i'm starting to pull my hair out since replacement coolent ain't cheap

Have looked in oil, no sign of water, no sign of oil in water either
Have pressurised the system using a bicycle pump bumped against darlek cap and found some leaks this way, do I need to drain all coolent out of system first to really find all leaks?
help me obi wan kenobi
your my only hope

You are basically on the right track using the bike pump idea to pressurise the water system as this one of the ways external water leaks are checked in most good garages.

You really could do with borrowing the proper tool (Water pressure tester) to hold correct pressure (shown on the top up tank pressure cap) while you have a close look for any thing obvious.

But if you are loosing water and you are sure it is not a visible loss it may be safe to say it might be due to the early stages of the cylinder head gasket failure ( water finding its way into a cylinder from the water jacket)....

ps, water system will have to be full during the pressure test....
