Hey guys, back again with more newbie questions. Ive got a 67 Skylark w a 455 and its lately been running hot. Ive changed absolutely nothing on the vehicle and temps have been creeping higher and higher. The fan (not electric) needs a shroud, but id drive it for hours in Houston summers and its never gotten as hot as it has recently. I dropped by a local car meet the other night and another 455 owner more knowledgeable than myself took a look inside the radiator as i i let it run briefly and said although it looked good and clean inside it seemed i had bad circulation. My question is: whats the fix? New water pump? New radiator? Im assuming they're both "original" in that theyre old and ive never replaced them. I flushed the radiator and double checked the 190 mr gasket thermostat direction. Whats left? Thanks in advance.
