I have a chevy 454 in a 82 class A Winnebago motorhome. After suspecting that the engine was running hot, I put in a stewart/warner temp gauge in the engine block replacing the original. On a 90 degree day up a gradual incline at 55mph, the temp approaches 220 degrees. After going over the hill and coming down (with less load) the temp comes back to 215 degrees. I had put in a heavy duty new radiator this spring and was hoping that this would keep the engine running cooler. Should I be concerned with it running these temps? I have seen a lot of discussion about fan clutches kicking in around 210 degrees. I know my clutch has not kicked in this summer since I have put the new radiator in. Is 220 degrees too high? Should my fan clutch be kicking in? If the temp is running too high, is my lack of fan clutch kicking in most likely the reason? What replacement brand fan clutch would you recommend? |
