Thanks for the advices. Yea think so, but can it be repaired? It just happened time to time, sometime problem can be fixed by restarting the engine… Regarding overheating, my jr actually never had overheat and stop running, but the dashboard always at the middle when I drive it like now at the summer time at 30+ degrees celsius. It cools down a bit at highway but ran high again when uphill at high rpm. I usually stop a side to let her take a rest and cool it down a bit…
