I have a 2024 model RX7320. The engine doesn't warm up and the heater doesn't keep the glass clear in below zero weather unless you work the engine harder than just putt-putt snow clearing. Kioti has the heater return going back to the radiator bottom tank rather than the water pump inlet (like everyone else does) which is just like having a thermostat that doesn't close. The engine is getting a steady flow of cold water from the radiator even when the thermostat is closed and it doesn't need it. Has anyone else in winter weather noticed this? Has anyone come up with a fix for this?
