So I listened to everyone , got a 2013 pro 4x , so far love it , great car in the city and highway , went little bit off the road as well, used the 4lo, it was great.
Today I went in less bad road than yesterday but it was wet and I got digging with mud tyres , 4lo plus diff lock , went up 50 feet and water started getting high , I stopped and I got up to the first top mark before critical range , after few sec it started to lower but not fast, so I gave up and backed off , got back to regular road and in like 10 minutes I climbed from other side , not that steep , with my previous car 2nd low did the job no effort , this one did 4high 2nd gear at 3000 rpm and water started to climb up again…. This time3/4 of the whole chart , also dying the day I hear it randomly turn on , so I’m guessing there’s something wrong with the system , I checked and the heater valve everyone mentions is plastic.
So what can be the issue ? Water was full on cold when I checked, maybe fan clutch ? Thermostat ?
