One thing I have learned in this place is that everybody is in denial about their radiators. At this age get it recored. It will be one thing or another with it. If your going to go through the effort of pulling it, recore it. I am assuming it's a GM With the GM temp gauge the halfway point is about 220-230 degrees. I have a second gauge that when the engine is at 180 degrees the GM gauge is about 1/4 of the way up. My radiator had to come out of the front. I was able to swing the A/C core up and out of the way and bungeed it to the wipers. ( didn't want to lose the r-12 )
Here is an explanation on everything that had to come out on mine. I pulled mine last spring. I took my time because my A/C charge is as good as gold. (R-12) By time I removed the grill,oil cooler,trans cooler,tied up the A/C coil disconnected the wiring harness the electric fans, bumper some of the fiber glass and then the bracketing holding the Radiator it took 7-8 hours. About 6 to put it back in. Getting the radiator recored was the best money I have spent on this so far Edit: When I took the radiator in, the guy showed me that the fins were pulling from the tubes and that the tubes were 3/8" he said it looked like they took an automotive radiator and sized it up to fit a motor home, it was a 4 core radiator. When he was done it was still a 4 core but it had 5/8" cores and he showed me the old core, they were plugged pretty good. He asked me what kind of fluid I had been using and told him Prest... he replied "I thought so, seems most of the recores he runs into use the same stuff. He said run anything in it but that stuff and I would be good to go. I now run at 180 degrees and never hear the declutching fan kick in except on decelaration
