4jg2 what part is this ?

Postby jackapoo » Sat Nov 27, 2021 4:47 pm

Hey guys. Can any one tell me what this black reservoir is that is connected to the break booster and the alternator on a 3.1 4jg2. It is making a bubbling/whining noise. Thanks

The whine is from the booster behind it. The black box is an additional vacuum tank

My guess is an air leak in the booster. My bighorn does it and the wizard I used to own also did without that tank
