NBaxter Posted March 17, 2021 Share Posted March 17, 2021 Hi all I am a new owner of a 2017 TC swb. I really like the van so far but I am going to try and lessen the noise from the back into the cab by putting some sound insulation foam and deadener on either side of the bulkhead. My question is, what's the purpose of the vents in the bulkhead and are they really needed for a work van? Obviously my soundproofing would be greatly improved if I could cover them! Any help would be much appreciated Nick Quote Link to comment Share on other sites More sharing options...
MLB Posted April 11, 2021 Share Posted April 11, 2021 Dont' have a bulkhead so no clue what vents you are talking about. Never seen a tc with a bulkhead other than adverts for such thing. Quote Link to comment Share on other sites More sharing options...
JackGrimshaw Posted April 11, 2021 Share Posted April 11, 2021 I have read that there are 2 vents in the rear pillars that allow air out under the rear bumper. This allows fresh air to come in through the cowl(unless you have the recirculate button pushed). They also allow you to slam your doors and not pop your ear drums. I imagine the bulkhead vents equalize pressure between the front and back Quote Link to comment Share on other sites More sharing options...

The bulkheads are needed for air flow and pressure equalization. You really notice the pressure when you close a lift gate. Quote Link to comment Share on other sites More sharing options...
