Cooling problem on a SB 1972....
I'm going to describe my problem and appreciate any help. Last year the car started to overheat (guage spiking 2 250) at standstill. When it got moving it came down to normal (210). I replaced the thermostat (160F) in the fall before putting it away and it seemed to help the problem a little but not good enough. I have records back to the 80's for this car and as far as I can tell, the radiator has never been touched (77k mi). I've checked the obvious stuff like the right side of the rad being hotter than the right and the upper hose being pressurized while running. I know the water pump was replaced at probably 60K. Before I pull the rad and have it re-cored, is there anything else to check? 2 mechanic buddies told me to re-core but I like toi hear all opinions. Also, any tricks to pulling that rad? It looks pretty straight forward.
