You’re using zic 10W40, keep using it and change it after 3500km. Use original air and oil filters. If want to switch then go for Shell Helix HX7 5W30 blue box.
Sir I also need help A week ago I drove about 70km the car became overheat Then I changed the fan to direct and remove thermostat Does it affect the performance of car
Sir ?
Yes it doesYou should have cleaned its radiator rather than doing thisAnd this is the wrong oil for your carRecommended grades are5w30 total quartz 90000w20 total quartz/shell 5w20 zic hx7 Change intervals for all these oils is 5-7k depeinding about driving conditionsThese are all fully synthetic oil Lastly clean your cooling system Pour collant either toyota long life collant or caltex Make fan auto install new thermostat valve and also check if radiator cap is keeping pressureThese modren cars wont last very long with direct fan and no thermostat
Babar Ali is right, You should have cleaned its radiator rather then bypassing the thermostat.you are using wrong OIL 0W20 is recommended total quartz/shell/caltex/honda which ever is available but viscosity should be 0W20.Change interval is 8000 KM if you drive in plains and you do not drive your car like a sports car. (which you can't as its 660cc car). if driving conditions change, check your engine OIL after 5000 KM.Use only genuine air and oil filter.Last clean your cooling system and pour in ONLY TOYOTA LONG LIFE COOLANT
Sir the car has travelled 65k
How did you know it overheat? Maybe cooling system has leak. Put thermostat back in and repair leak and pour fresh coolant. Running cold damages engine and reduces its life.
Sir it showed on the meter the light was on that how I knew
Was it red sign? And when it was overheating did you check radiator that it has water/coolant in it?
Sir it has water in it not coolant for now
Sir car 65k chali he aur abh kon sa oil use krne chaye Ac used mostly
Use total quartz 9000 5w30
Sir the water flew to expansion tank but does not come back ?
fill your radiator circuit with water, drive your car for like 10-20KM, check water level if its significatnly less than you poured in than there is a possibility of leakage in radiator circuit, or may be (less chance) your engine seal is damaged
