Summit, Jegs, etc. sell washers with various size holes that restrict flow. I havew made stainless steel washers that fit snuggley in the hose from the thermostat housing to the radiator and put it in the hose jut beningd the radiator inlet nozzle. You can have the impeller turned down to a smaller diameter but go slow with this - the effect on flow is squared. If the impeller is shrouded, remove the shroud. Also, you can use a 'low performance' (small flow area compared to 'high performance' thermo) thermostat.

Best way is to put some sort of restriction in the thermostat area so the pump is still putting out full pressure and that pressure is built up in the engine block. This helps prevent nucleated boiling.

i have a 160 thermostat and if i reduced the coolant flow would it keep my motor cooler cause the 160 runs hot almost all the time.

You probably have other problems to address before hand. Give us a description of the symptoms in as many details as you can and we will see what's going on.

Restricted air flow is the problem 99% of th time assuming the system components are in good repair.
