Bongo Fury

Hello to you all,could some one please help iv had my mazda bongo standing in my garage for 6months i started it up today and found water dripping from a hole in the cover which covers under the engine.I kept the engine running for 20 minutes but the water which dripped out was still cold,i had the heater running and that was nice and hot.

has it lost any water from expansion tank

It could just be condensation, but check the expansion tank level, if it's gone down, it's leaking out somewhere, check all the hoses etc under the seats & in the engine bay if so.

No it seems the same

Personally I'd lift the seats & check oil, gearbox oil & steering fluid levels anyway if it's been sat that long, give all the hoses etc a check over anyway, only takes 5 minutes, check there's no swelling or water staining.
Sounds like it's just condensation that you're seeing though.

If it's stood for 6 months, it's probably worth having the oil changed as well - unless it was done just before the lay-up. Also run your aircon to get the lubricant to the seals.

When i put aircon on i could hear a whining sound

slipping belt maybe? does it get cold?

Yes it gets cold
