.040 Over
Finally got some time off work and decided to change the coolant on my Rocket Roadster. Never changed it before; anyway, plugged in DealerTool and turned on the bike to get a pattern of what the bike coolant temp readings are. By the way, the radiator is full along with the overflow bottle. Once the bike heated up, the fan came on; also, the temperature here is HOT (my truck swore it was 105 F). As I was monitoring the temperature in Dealertool, I noticed the fan never shut off. It was reading 106 C (about 223 F); left it on for a few more minutes, and the fan never shut off. I then plugged in my OBD reader to take the bike out and as soon as the bike gained some speed, the temperature started dropping. Riding the bike, the temperature was around 200 to 210 F.
There were no codes, overheating lights, overflow issues, or nothing like that; just feel that those temperatures are too high. I then went home since the coolant temperature does drop once the bike moves; I assume then the system should be working, although, maybe not efficiently.
Parked the bike outside this time (initially I had her on in my garage) and the same pattern was there. Temperature read up to 234 F; took her out for a quick spin and it drops about 10 - 15 degrees fairly quickly.
Again, no leaks, no lights, no codes, no overflow, but it just seems like the coolant temps are too high; anybody else seen this?
Also, I touch the hoses before the fan comes on and then after the fan and you can feel the temp difference; not sure if that's a good sign or not. Any info would be appreciated; I am changing the coolant but also going to boil some water and test out the thermostat. The service manual calls for about 190 F before it opens; 190 to 234 seems like a range too wide for me. Unless the reader is wrong since no lights came on.
Please advise.
