Of course, use the bleeder on top of the thermostat with the car off, engine cold and pour coolant in the radiator until a steady stream comes out with no bubbles. Close the bleeder and crank the car, let it get up to operating temp and keep the radiator topped off until no bubbles come out of the neck, do it with the heater valve open (slider to red).

If the fans cycle twice and the lower radiator hose is still cold or not as hot as the top hose going to the head then the thermostat may be stuck closed. Give the car time to warm up to be sure though. You can hold the engine speed at 3000 rpm (this will not hurt and is recommended in the manual) to speed up the time to bring the engine up to operating temp but if the car starts to read hot and the lower hose still feels considerably cooler than the upper then replace the thermostat.

Saw your other thread, don't buy aftermarket parts, they're junk as you have most likely have realized, fitment and function is always a problem. The way those companies develop parts is by just making a cheap copy, absolutely zero engineering is involved. Buy parts that were designed and engineered to work with your car.

it's hurting by not using OEM Honda that have built in fail safes in addition to using something that has the wrong opening temperature

do it on a flat surface, or with the front of the vehicle raised up a little. and do it exactly how minilogoguy said above.
170 is entirely too cold of a thermostat. 192/195 is factory, use a factory spec thermostat.
if it's a full out race car, use a 180 or 185. typically anything lower than a 185 will not work well with a stock ecu though, it'll make your gas mileage worse, and LESS power. so unless your car is built up and tuned properly, use only 192 or 195 thermostat

it's actually best to jack the front end up as far as you can...this guarantees you get the most amount of air out...also make sure to open up the heater control to full red(away from blue)
