- when the matrix leaks, is it usually into the drivers' or passenger side?
Don't know
- is it ok to clamp off the rubber tubes on the bulkhead, as I have seen on YouTube? I'm not mechanically competent enough to drain all the coolant down
Not recommended as you could damage hoses.
- when I come to remove the matrix, which side will I need to pull it out from (passenger or drivers?)
Driver side on RHD car
- is there a good place to source a new one, or do I just use eBay? OEM is Behr, is that right?
