    The heater hoses are connected to the heater core just under the A/C hoses on the right side of the firewall. There is not much room back there and not much rubber hose to install a flush tee. You may need to find another way to flush your cooling system. Don't forget, used coolant is considered hazardous waste. Please dispose of your old coolant properly.
