Hi, since buying the car I’ve had a new (second hand) heater radiator waiting to go onto the car as the tube on the left has snapped in the firewall. Can someone help me as to how I get the old one out? I’ve taken all the push rods off and all the cables I’m guessing I need to take the whole dash out? I’ve also loosened the Phillips screws and managed to open it down the big split in the middle of the big black box behind the dash, but can’t open it enough to get the heater rad out and new one in. If anyone can let me know whether it’s a dash out job and how to do it that would be great thanks! ?
