Our 94 Coachmen Santara with the Chevy 454 motor had some overheating heating problems in our last trip thru W Virginia.
On long uphills the temp gauge would get close the the red marks.. We turned off the ac and turned on the heater to help dissipate the heat.
What is odd is that our fan clutch did not come on.. It has been sporadic when it would turn on/off. I have seen it come on at 170* and other times it would not come on at 240*
So I decided to replace it.. The oem chevy dealer wanted $300 for one.. Ouch.. Napa had one that they said was exact same and met all the same requirements.. $60 Since I am retired and trying to be frugal... (cheap) LOL.. I went with the Napa one.
Big difference.. This one comes on partially at 180* Full roar at 210* It will cool the motor down to 170 then shuts off..
But it seems to engage a LOT.. Running on level ground ,65 MPH no ac on, outside temp 80* it will kick on/off often.. 20/30% engaged, not full Roar... Have not had a chance to take it to any mountains to see if it will keep temps down or not. (we are going to Kentucky this weekend, but dont know if we will hit any long climbs near hopkinsville KY)
So my question to all you chevy 454 owners is, does your fan clutch engage a lot? How often and at what temps?
