Default Normal temp.

I have 1997 Buick Park Ave NA. On the highway the temp is at 200-199 In the city with the ac on, the temp is 225. I have a new water pump and a new tstat. Fans work low and high. When car is hot i'm able to take rad cap off with out getting burned and ther is no flow. Do you think I need a new rad ?

Personally, I would NEVER attempt to remove the radiator cap when the car is HOT. But you did wihout getting yourself scalded. Which could mean that the radiator cap is shot because there is no(or little) pressure building up in the system. IMO, I think everything is probably fine(but then again I'm an Optimist so take my opinions lightly). I'm also a cheap SOB so I don't like to spend money when I don't have to. I'll assume (for just a minute) that since you replaced the WP and the T-Stat you also put in fresh Coolant. If NOT, then I would flush out the system with some radiator cleaner, back flush it(with one of those kits from Prestone) and put in some new coolant(50/50 mix). Did I mention a new Radiator Cap? Also, if you have never replaced the water hoses, this is also a good time to do that as well.
You didn't say where you're from, but here in the East, temps have been in the 90'*. And if your car sits in traffic with the A/C going at full blast, coolant temps at 225 sounds normal to me.
After reading this over, you stated that you have no water flow(circullation). I would think if there was abolutely No water recirculating, the car would definitely overheat. It'* rare, but the new T-stat you bought might be defective, the wrong one, or installed incorrectly. Some people on this board swear(@#$%!) by a 180 degree T-Stat. You might want to try one of those "puppies" to see if things cool off. Good Luck.

Agreed, may want to try another thermostat... On the road with a stock 195 the the temps should stay near 200F even on a 90* day... If you were in traffic without the AC on( Fans running ) then 220F and a wee bit higher would fall into the normal range...

I swear(*%$#^... LMAO ) by a 180F as I live in a warm climate( Gotta love Florida Winters ) so its warm most of the year here... But if you are up north and it gets frigid cold than you would be better off with the 195F... And I have had a thermostat that was junk from the get go in the past... I have also seen a few in other cars...

Good Luck
