he engine could be using both water and oil, burning it! scan it, check for DTC codes... looking for a misfire you will not feel it. Then have the radiator coolant checked for Co and HC(head gasket) nothing beats a gas analyzer, a decent facility can check this for a minor fee, of buy the chemical test strips or cylinder style kit, finally have the exhaust checked for Co2 levels. You find the path the liquids are taking as they leave. Regards

Sir, thanks for your answer, please could you clarify me what means Co in the radiator and HC(head gasket)? To correct the mistakes which parts I ahve to buy commonly in this situations?


Co means that burnt and Unburned fuel, from the engine is leaking past the head sealing surface, the head gasket..when this happens it allow by products of combustion to enter into the coolant passage areas contaminating the coolant, its possible to detect these, CO, (Carbon monoxide) HC, (Hydrocarbons) etc. This is also an indication of COOLANT burning in the combustion chamber resulting in a loss of it. One path of loss in terms of the coolant and not uncommon. Once this is determined by testing either the head gaskets or cylinder head will need service.

Thanks once again for the reply, as I am in Angola-Africa and the devices for such diagnosis CO and hydrocarbons are not available, I would like to know what parts must be changed as I have to import them from USA.
