Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello I will help you with your question,
I am unable to speak on the phone but I know the valve you are seeing the leak from. This is a vacuum operated water valve and is in a very awkward position to replace but that is the cure for your leak.
Yours looks like the one found at this link?
Use new hose clamps and you will probably have to dig pieces of the old plastic out of the hoses. Be sure to get it all out. mark the hoses before you take them off!
Please let me know if that is what you are seeing
