The main problem with thermostats rated at 180 or 160 or having none is it takes longer to get the engine up to operating temperature and also the HVAC heater.

I see, I don't have to worry about the HVAC heater temperature since my heater core stopped working a long time ago, maybe I'll replace soon who knows... so, bottom line: Will I have any other problem besides the engine taking longer to heat up?.

You might be right, yet we have to take the car twice every year for emissions test. But even if that wouldn't be an issue I still care about environment and the only reason I kept driving it without a t-stat was because the "mechanic" who fixed a cracked head didn't put the original back in amongst other things (literally broken MAP sensor, no air filter installed and so on...) that was about six months ago, but the car was sitting for 3 months because of a broken trailing arm and lots of problems at home...
and the other 3 months I was working on the other two rides we own.
Thanks for your help Bob
