Hello, new owner here. I have a coolant leak from the right side (as you look at the car from the front) where a metal plate bolts to a block. In the pictures and linked video you can see the dried pink residue. Can anyone tell me if the plate that bolts to the block has a gasket that's replaceable or is there a seal built in to the metal part that bolts to the block? Depending on the answer to my question, I would be grateful if anyone had a part number. The car is a 2012 reg WV62YSO.
