Default thermostat...

Did you install it upside down?

The spring side of the thermostat should be down so that the temperature-sensitive spring metal is in contact with the the hot engine coolant so it can open the valve plate.

I hope that this helps!

The only other suggestions are:

New thermostat

Check the radiator fan to see if the fan clutch is working. The fan should turn by hand - but only after applying some pressure. If it turns freely, the fan assembly needs to be replaced.

New water pump. If this is the case, DO NOT attempt to remove the timing belt cover by loosening the big 17mm bolt in the center of the crankshaft! There are 4 smaller bolts that hold the accessory pulley to the crankshaft via the crankshaft timing pulley. Remove those 4 bolts in order to remove the accessory pulley! Refer to the Samurai Factory Service Manual - a downloadable pdf file at Ack's FAQ (see signature below for the link) - for detailed information. Do a search for fsm and select the '88 Samurai FSM link.

I hope that this helps!

No, a 165 degree thermostat will not work properly. The engine will run best at the right operating temperature, which is determined by a 195 degree thermostat.

The cheap solution (165 degree thermostat) will only be a band-aid solution.

You really need to check the fan clutch, belt tightness and look for problems with the water pump.

Try running the engine from cold with the radiator cap removed. If the water pump is working there should be circulaton seen when looking into the top of the radiator core. If not, remove the thermostat then look again. If there is still no circulation then you probably have a water pump problem. Remove the belt and hand-turn the pump. If it is hard to turn it's replacment time.

Also, check the water pump drive belt to see if it is tight. If it is loose, you might have belt squealing and charging problems.

I hope that this helps!

Default running to hot

sometimes if the rig runs a little to hot with the right thermostat installed it could be a flow problem and by drilling a small hole in the thermostat it can help this problem. Just an old school trick that works.

Remember, the thermostat doesn't really control if it cools or not, it just controls at what temp the engine runs at. Your cooling system cools.
If you are overheating or running hot, make sure you ARE running hot. Is the temp gauge right? If so, as someone else said, check your flow (water pump). How old is the radiator? Is it clogged? Fan shroud on? How are the fins? I do my mix stronger than 50/50.
I've got a friend that can't understand why his rig runs hot... he has so much crap in front of his rat it is amazing. Bumper, air horns with compressor, this, that... gee, it runs hot, wonder why...
All that said, years ago I used to run a cooler thermostat and hotter plugs in the summer, then change back in the winter. Once a year I did a total flush. That was back when I had money.
I also have a electric fan in front for when I rock craw. Then again, I also have more than one heater core and fan. (got tired of the wife saying she was cold, now I can roast her)
