sounds like water pump problem or the fan 2nd speed is not functioning well.Hi bros, might need advise from sifus here on my car problem. My Exora (CFE) recently having temperature hike during uphill (no matter no/off aircond) which the root cause yet to define :(
Step had been taken/done:
1. Engine oil changed
2. Radiator pressure checked (no leaking)
3. Coolant water level checked (no need to top up since last service)
4. Fan fuse checked (no issue)
5. Thermostat changed (requested by me during 2nd visit to Proton SC)
What should I do now? The SC foreman informed me that my engine might need to open up and check for the abnormality. Should I do so or something else we should check/do before we take the last resort? Please help me :(
