hi, one of the easiest ways to locate where its leaking is to get a large piece of cardboard new if possible and once you've got the car and coolant hot, park it up and place cardboard under engine bay on ground ( complete area if possible ) and leave it to cool down for an hour or two and then check cardboard for water stains !!!!!! mark the cardboard to nearest point of the tyres so you can then judge where the location is !!!!!! it worked for me in july last year and unfortunately one of pistons had gone , wasn,t cheap fix sadly ,,,,, hope this helps and hope your engine is ok ,cheers mozz :crazy_driver::crazy_driver::crazy_driver:
