Hello, 

Coolant thermometer gets to max temperature after about 7-10 minutes idling, above the 237 degree marker.   However, the coolant temperature light does not turn on.  Radiator hose is cool, the hose to the block is hot, but not extremely hot.  The engine block doesn’t seem to be hot either.  The thermostat opens up and works. 
 

Does anyone know what the issue could be?  Faulty water pump maybe?

I ended up replacing the thermostat and flushing the radiator and coolant with new coolant.  It was quite dirty.  Seems to be working better, but still running a bit hot. I also bought a new water pump for it and going to end up changing that to see if that regulates temp much better.

      2018 Hisun Sector Crew 1000 engine die after about 15 minutes run
      By Hugh
      My 2018 Hisun sector crew engine cut off after about 15 minutes run. There is no indicator of what is wrong, no error code just die and won't restart until it cool down. I notice that the fan is not running but the temp indicator is on low temp, no overheat indicator. I checked the radiator fluid, it is cool to touch.
      Cooling fans are working, I can hear it running once awhile if I can get the engine warm up enough.  Thank you for all the help.

      Coleman 2022 UT 400 radiator thermo switch replacement question
      By moonrover
      Mine is overheated/burned/melt at connection with its wire connector, parts are ordered to replace both them.  This seems to be a common issue, and some of you already replaced it. I right now just connect the wires, so the fan runs  all the time whenever the initiation is on, but it's better let fan runs as needed with a working temperature sensor/switch. 
      Question: Does some coolant come out by removing the switch/sensor from radiator?  Or, is the threaded hole all the way inside radiator?   If the answer is yes,  I want to drain or extract  some coolant to make its level below the sensor before replacing it, so I don't make a mess with coolant spilled out 
      Thank you.

      Just wanted to check in and say hi to fellow members. I bought a 2023 T-Boss 550 last month just in time for hunting season. So far all is well. I went over it to check things out and learned a lot in the process.LOL! I certainly would recommend that all new purchasers should make it a point to do this because I can promise you that you won’t regret it.
