So I've had my truck for a year and this has happened every single time you turn off the engine sounds like a gargling or a plunger sound... It's random and sometimes it can happen a couple of minutes after the engine is turned off but it's every single time.
This cannot be a normal sound because it's loud it echoes and when people actually hear it they turn their head sideways so can someone please tell me where this is coming from?
