I tried it, but I'll be honest it's hard to gauge and really really hard to tray shear what area it's from. It's definitely low down but there's a lot of sort of like echo making it seem all over the place, a bit like a wheel bearing on a car, always seems different places.
Wouldn't be surprised, as I said it was second hand last year. Did notice a drip or 2 of coolant near it but nothing on the floor yesterday. It has also just been out so I did put it down to that being the problem
