Don’t forget to add a bypass not just shut off valves. If you merely deadhead the supply line you can create problems. The coolant system is designed to have a certain amount of circulation even when the heaters are in the ‘cold’ position. Bypass ALL of the remote heat, especially the dash heater.
You need 2 T-fittings, 2 ball valves and a bit of hose. Put a T fitting in the supply line with a ball valve just downstream of the T fitting. Then connect the 2 T fittings with some hose with a ball valve in the middle.
Summer time the ball valve in the bypass line is opened and the one in the supply line is closed. In cool weather the positions are reversed.
A bypass setup will also keep the dash A/C working FAR better.
