I have seen new radiators come partially blocked. Take it down to a good
radiator shop that can do a thermal image or a temp probe check of
radiator temps top to bottom and side to side. There were issues with
plastic water pump vanes eroding, so make certain you have a metal
impellor if you go in there.
My 90 was running 90 to 100 up until this year - it now runs 95 on the
highway, 102-105 in town - rad, water pump are 4 years old so I expect
I'm getting some clogging. Is the system holding pressure? That can be
an issue also.
- and I run a thermostatically controlled 14" pusher fan in front. These
cars do run hotter than most people expect.
