Re: Water under car

Get some red food colour from the baking dept of your supermarket and put it into the engine cooling system, by the radiator cap , expansion tank, or whatever you use

Then see what colour the leak water is. This will tell you if the water is from the cooling system, windscreen washer (which will presumably be blue), or aircon
It might even tell you whereabouts on the cooling system the leak is

It'll probably take a couple of days for the dye to work its way round, depending on the mileage you do

Yes, a pressure test on the cooling system would be useful, but perhaps leave it till after you've added the dye, then you're more likely to see any leaks

Yes, I realised that and was not making any comparison. I was just saying that as a person who previously used to service and repair my own cars I now know from my VW Golf just what the modern car is like in that regard – impossible!

My other car is now 35 years old and has a 2.8 litre V6 Ford engine, all components are easily visible and accessible just by lifting the bonnet.

On modern cars that might just about slide underneath by itself, I would probably have to lose about 90% of my body to be able to slide underneath my car on one of those!
Ha ha me too.

Re: Water under car

Ah yes servicing one own car, those were the days. replacing big end white shell bearing. Decoking valves with a rubber sucker on a stick on the port heads. I hate to think of the number of clutches I have replaced, can't find my clutch aligning tool now. May still have a ring compressor somewhere but no idea what happened to the timing light. Must really have a good hunt around sometime to see what I have left lying about

Re: Water under car

Others have answered most possibilities, but the a/c will deffo drip water from the drain when in use. Just normal condensation and nothing to worry about.

Re: Water under car

Thanks all - most helpful.

Have just thought - my aircon has NEVER been used during the last 6 years. Is it likely that lack of use for a long time might cause drips?

No, but it’s probably allowed the seals to dry out, and the gas to escape..I doubt it will work now anyway, if you’ve never used it for that length of time..

The weather is very humid at the moment which equates to a greater volume of moisture from the aircon...
