Re: winnebago chieftain 454 overheating? by JOHN H
Post New Message To Russel Thanks, for your followup, that's a big relief! I was disappointed after spending the money on the new radiator, but now feel as though I'm okay. The fan clutch used to kick in before I put the new radiator in and yet I didn't really know what my running temp was with the original stock gauge. From what I recall, I never really drove the motorhome in serious hot weather after I put the stewart warner gauge in. I did replace the original in the same location (between the two exhaust ports). Thanks again.

Relieved,

John


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.

220 is not an excessive temperature. Especially when you consider where the thermal for the guage is, right between two exhaust ports in the head. (if you put it in in place of the original). A stock spec fan clutch will come on strong at about 230. Assuming you have a 195 thermostat, (which is good) you are running about normal.
