Please check the AC pulley is rotating freely. It can also be a case that bearings of the AC system which are connected by different belt are damaged or not rotating freely. If this is the problem normally there is more noise. For checking this you need to remove the belt which is connected to AC stuff and rotate and check it. If the bearings or some thing is wrong with AC, this will require more power from the engine to rotate at low speeds, which gets the engine to heat up. Correct me if I am wrong.

Thanks guys. Checked the whole cooling system. Everything fine. Checked AC Fan. Good too. The fan revolves freely no bearing or any other problems. AC Fan fuse went bust while trying to check the electricals. Replaced the same. Engine still heating up.

Have to check compression as the engine is run 100K kms.

Sorry was busy over the weekend couldnt check anything else.

Yes I am in Bangalore. But from Panaji.
