My LJ73 (2LT diesel) sometimes overheats (well at least the temperature gauge reaches the red zone). It does that if I drive fast (~100km/h) for a while on a motorway that goes uphill (even not so steep). I usually either ease off the accel and take it easy (70-80 km/h) for five-ten minutes to get the temp back in the normal range (middle) or sometimes if that doesn’t work I stop and let it cool down engine off before getting on my way again.
Any pointers?
