Well, it has been like this for awhile and I need some help. My '87 K5 seems to get real hot...not meltdown hot, but hotter than I like during driving in hot weather or up big hills...210 up to 220 or so. I have replaced the radiator already, the T-stat was replaced about a year ago. Anything I shoudl look at? It has the stock fan (132k on stock motor), the water pump was replaced about 5 years ago, but isnt leaking at all that I can tell. But my overflow seems to empty alot and it was dumping good this weekend after a hard drive in high heat. What should i look at???
