Again, there's nothing wrong with the thermostat or anything else. This is normal behavior. The temperature gets up to about 175 degrees under a fairly heavy load even with 25 degree air blowing across the engine and the bypass allowing water to go around the fully closed thermostat. I wrote all about boiling the thermostat on the stove the other day on this forum. I have many years of experience as a mechanic and I even do my own engine overhauls. I've dealt with many bad thermostats over the decades. This is not a bad thermostat. I can't get my Detroit Diesel to warm up in cold weather without loading it either. Do I need to change both thermostats in it too? What about all the commercial truck drivers up north who put a winter front on their radiator to get their diesel engine to warm up, do they need to change their thermostats too? Do I need a thermostat on my air cooled motorcycle because it certainly won't warm up at 25 degrees even with a load on it. Most of you have missed the whole point. I guarantee if I replace the thermostat with a solid disc the engine still won't warm up at 25 degrees unless I load it up. I'm not gonna do that because the thermostat actually works and I learned years ago not to disturb a working thermostat because it's difficult to find one that works well... Just the other day someone on this forum told me the engine will overheat if I REMOVE the thermostat... no really! ...I don't know why I even bother to post anything on this forum. I can write something important that's proven true only to get a bunch of foolishness from armchair RV owners who use their coach so infrequently that they have algae in their fuel and other "lack of use" problems. I'd kinda like to start a whole new RV forum restricted to full timers who have actual experience and know what they're talking about.
