Thanks so much for the info. A Hisun mobile tech is supposed to finally be here today to "fix" it after 6 months of waiting on them to send parts and the mobile tech has been here 4 times already. I have filed a complaint with the WV Attorney General to try to get my money back and just return this machine. Its officially 1 year old as of Dec 30, 2025 and its been broken down and sitting under the car port for the last 6 months with the overheating/bubbles in the overflow issue. Its only got 406 miles on it and never been off road at all.
First visit, the Mobile Tech said was temp sensors bad, ordered sensors and left
2nd trip brought temp sensors and replaced didn't fix issue so determined it was the water pump, ordered water pump and left
3rd trip didn't bring water pump because he now thinks its the head gasket and wants to do "some tests" determines he is pretty sure its the head gasket, Orders head gasket and leaves.
4th trip he starts working on the machine and takes out the timing chain tensioner and determines it is "sticking" and there is no use to change the head gasket without fixing that first, Orders the tensioner and leaves.
So who knows what todays visit will entail...............
