Xulfiqar bhai - With reference to my earlier question dated 28/09/2011, I still haven't managed to overcome the heat-up problem of my Sunny 2.0D (CD20). As per your response, I ensured that there were not any air pockets in the engine cooling system. Apparently, the engine of my car doesn't have any problem i.e. it doesn't reduce the engine oil, it does not produce any bubbles in the radiator. Also, it doesn't reduce water within radiator. The radiator is also new so there is no question of rust in it. I have also changed radiator cap couple of times but it didn't help. Couple of mechanics say that if apparently everything is clear then the last thing to check is Head Gasket - they suggest to replace it. However, I have a doubt that if there are no bubbles in the radiator then how could it be the head gasket problematic. What do you say - Can gasket be an issue if there are no apparent signs?
I have noticed that in the reservoir bottle, the water was quite rusty which lead me to believe that the engine is rusted from inside (yes, you indicated this in your response dated 28/09). How can I ensure that this is case? And if it is true then what is the solution to overcome the rusty engine? Will I have to replace the engine anyhow?
Looking forward for your advice. Thank you
