which 5?

follow lower rad hose where it connects to the block...

The hose should connect to a thermostat housing which (as name indicates) houses the thermostat

Be carefull that there are numerous other reasons that might cause vehicle to overheat, rather than thermostat...
ie: air trapped in system, expansion tank cap not sealing (can be pressure tested), water pump impellers broken, etc... Blown head gasket,etc...

You get my drift I guess...
