I had a new coil installed 6 months ago in my 2002 Saab 93 SE and it has been running fine until the other day when the engine started rumbling quite violently.
Took it to a garage and after they took the coil out they found a clear, odourless liquid which appears to be leaking from the coil. Would assume its "oily" water but they aren't 100%.
Any ideas what it might be, and how or where the liquid came from? My understanding is the coil is covered, the car is in good condition and there aren't any other visible leaks.
Having a new coil installed tomorrow.
This is what the part looks like if that helps.
