Two blue plugs drain the exhaust manifolds, one on each side of the block, two on the raw water pump on inlet and outlet, one on the low hose into the water circulation pump and on mine one more on the transmission heat exchanger. Heater return is usually at the intake of the water circulation pump and source for the shower and heater are usually near the thermostat. They might have disconnected the hoses at the heater and shower also.
I hope that helps.
