I'm in the market for another disco, looked at 5 so far. The latest prospect had what sounds like water sloshing around under the dash. Didn't do it when accelerating or braking, just when turning. So from what I've read it has air in the heater core. The owner didn't mention replacing any cooling system parts. Can the head gaskets cause this?

 

Either that or maybe drains in the cowl plugged and have water in it . But I am new into these so sure season member will point right direction..

 

Air is in the cooling system. Could be simple and wasn't filled properly or honestly it could be a bad engine. Mine did the same thing when the block (slipped sleeve) took place. Major repair cost if that's it!

If you are interested in it I would pay for a compression and leak down test to be sure! Even then there could be issues though... I would personally stay away

 

Could just be the AC nipples, but I wouldn't trust it. Run away.
