I have a Komatsu D65 EX dozer which overheats after 20 minutes of work. I already put a new radiator new waterpump new thermostate and a new fan. Then it takes 10 minutes to cool then work again for 20 minutes and then do the same. What can i do.
What series is it? If it has a hydraulic fan then I think that would be the next thing I would look at.
A serial number is going to be needed in order to figure out which machine you have.
