Silverline 154006 Mechanics Stethoscope 320 mm £5.44 @ Amazon

Quite a useful tool, saved me lots of trouble few times. Much better than the screwdriver trick especially for the inaccessible places.

Wonder how many mechanics tell their car to breathe in and breathe out?

The old man use to listen via a long screwdriver and hold his ear to the handle

Cough

I use a screwdriver but tend to just rely on if it's one fire it's broken if not it's golden

If you don't hear 1 gallon, 2 gallon, 3 gallon in a timely manner, it maybe time to check the old tailpipe (edited)

These are dreadful quality and unusable, other than as a prop.

I feel a new career coming on, NHS really needs more Doctors

Thanks OP

For the wannabe docs out there...

I'd like to see someone trying to use this on a dodge demon

"I'm just going to listen to your urethra"

Stuff of nightmares.

Seems more ideal for use on patients with bull****

a good mechanic can often use feel and listen without a stethoscope, but that is an old fashion skill even doctors are hardly trained for

I think you may be able to hear if there are any leaks in underground water pipes as well.
