The temperature seams to climb to 195 or even 210 at idle. When the RPMs increase the temperature drops to 180. When I shift into 3rd gear temperature begins to climb until RPMs increase. What's happening? The water pump is rebuilt.

My other engine seemed to be constant at 180. This is a rebuilt 216 bored over 40 thousandths of an inch.
