Correct, pump is on side of block, it pushes thru the block, into radiator, out radiator to thermostat, then thru the pipe from t stat to back of pump. If you are having an overheating problem, remove the plate on the front cover( has 4 small bolts) and make sure gear will NOT spin by hand. I have seen the balance shaft chain break(spins pump) and not make any noises or cause any problems other than it will run hot.
