Toyota Avensis T25 2006 after lifetime. Mileage: 180 thousand Engine: 2.2 d4d 150km
Previous repairs: replaced engine + water pump under the warranty of ASO at 114,000 (2012) Documents show that there was a problem with the loss of coolant. I am the second owner, the repair was when the car was not mine yet.
Current problem: He ejects the coolant through the hose, with the tank unscrewed, the liquid bubbles and evaporates, I feel that I feel the exhaust fumes (I ordered the meter to confirm) The car does not smoke, the exhaust pipe is dry. There is no oil in the fluid and no traces of oil in the oil. Despite the fact that since the replacement of the engine the car has only driven 66 thousand. is it possible that the failure has repeated? (I don't want to believe that the engine withstood only such mileage). I called the ASO, they said that after this warranty repair, they did not happen that someone returned with the same fault, and after 66 thousand km it was very unlikely.
Is there a chance that something else has fallen? For example, egr cooler? (apparently the symptoms may be similar, i.e. exhaust gases in the cooling system, depleting fluid, I do not know just how with this discharge through the hose - although if the pressure in the exhaust system is higher than in the refrigeration system, it would probably be possible)
The car drives normally, the engine runs evenly. I am green in this topic, and I do not want the mechanic to stretch me on the head gasket. What do you think?
So if exhaust fumes come out on the test, is it 100% certainty that it is a head gasket? You don't want to believe that Toyota replaced the engine that has driven 66 thousand. km which is less than the one with a disadvantage.
The gasket itself will not help, in these cars the block bends, or do it all, i.e. planning everything and everything. You can also replace the engine, the version without d cata is cheaper and does not have this problem. I suspect that burning dpf is overheating this engine.
It is not a damaged EGR cooler. If this were the case, the fluid would get into the exhaust gas and then there would be steam from the pipe. In my opinion, the head for the photo and planning and the best engine block, although I would be careful with this because I know from practice that there is usually the thickest gasket there, so then there is nothing to put on. Other engines in this series have the same disadvantage, I repaired more often 2, 0 D4D than D-cat. The cost of repairing such a unit should not exceed PLN 5,000
The same is the problem with the 2.0-116 hp d4d engine. In a different power, this disadvantage does not exist. Check if it is not reamed 116 km to 2.2 l. If the seal is broken, it is better to sell it.
