We are new to RVing. We purchased a 92 Fleetwood Bounder, 34 ft. It has a Cummings engine and Allison Transmission. It runs excellent EXCEPT for when climbing hills. The temperature gauge sits at 180 degrees until we start climbing and then depending upon the grade it can raise up to over 210 degrees. Within 5 minutes of pulling over, the temperature will drop back to 180 degrees and if we idle longer it will drop down to 160. We've replaced the thermostat, raidiator cap, had the radiator rebuilt, replaced all the hoses and fan belts. We also of course had all the radiator fluid replaced when we replaced the hoses and rebuilt the radiator.
Any other suggestions?
Hill climb in a LOWER gear...thereby causing engine RPM to run higher and fan to spin faster....getting more air thru the radiator. DONT depend on the auto trans to know when you need to downshift....YOU do it manually
