this in in my 1974 B body van with a 318 2 barrel engine.
i have been messing with this overheating problem over the past year and have yet to figure it out.
the engine is the original 318 2 barrel, it stays cool around town and going down the highway. When i get stuck in traffic it starts heating up. it had the original fixed blade fan (no clutch) and radiator with shroud.
i replaced the original thermostat with another 180° one, it made no difference.
my plan is to install a 440 in this van so since i had everything sitting here i went ahead and installed the 440 radiator and shroud. i used the fixed 6 blade from a 1969 383 engine.
it runs cool around town and going down the highway about 180-190° but if i sit in traffic for 5 min it starts creeping up ive seen it as high as 240°
could this be a water pump issue?
