How to Fix Passenger Cowl Vent Seal Gap

There isn't a notch in the rim of the cowl collar where the J hook is supposed to sit. The hook should find plumb stance though. Assuming you have the correct new seal ( about 3/4 inch square profile foam ) it should conform and fill the gap. By the way... the peal paper to expose adhesive on that new seal is a joke. Glue it to the heater case with a bead of weather strip adhesive. Otherwise it wont stay in place and its glued ends will separate, you'll have C instead of O.
