The best method for installing the thermostat in the radiator upper hose is the hot water technique mentioned. Boil a pan of water on your stove, set aside, then insert a new hose to make the rubber more pliable. Apply some plain old liquid dish soap all around the outside body of the new thermostat then work your way into the upper hose from the radiator end. The unit is inserted with the pointed end towards the radiator. The original hose had a band attached to the upper end in order to keep the unit from slipping down towards the engine when system got hot. New hoses made by Dennis Carpenter have this band but if you don't have this band, you can use a plain hose clamp or a plastic wire tie. I advise to use a new hose when doing this. Rubber will lose some properties over time and harden up. That makes it more difficult to work with. I've used WD-40 to lube the thermostat for insertion a few times too. Soap and WD-40 won't do any harm to coolant. Here is an older post on the cooling system you may want to keep for reference.
