Toyota Avensis T25 2.2 D4D - Coolant ejected through the hose

Hello,
I will briefly describe the car's story:

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?

If you suspect an egr cooler then bridge the fluid circuit then you'll find out.

The problem is I don't really know where she is. The EGR valve starts just above the tank with the coolant, but I can't locate the EGR cooler.
I'd like to check it out before visiting a mechanic.

I attach a photo, will you help locate?

Is access to this radiator from the bottom of the engine?

I looked through the pictures and I see that your egr has no cooler.

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.

I do not have a good opinion about these cars, listen to the users and it will pass you.

I knew about this defect, but I assumed that since the engine is new, I would do 100,000. Toyota engine after 66 thousand and replacement of the head gasket, it's ridiculous.

Hey, I'm new and have pretty much the same problem. Has anything been done? What cause? Kisses

Head gasket.
I add the liquid and continue driving, because the repair is 50% of the car's value, so I don't plan to do it.

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

Hi, my Avensis 2ad-ftv 2005/06 has the same issue with the coolant. Not yet repaired, but working on it. (The full front=egr, oil cooler, hoses, intake, radiators have been cleaned and checked)

Soon will move on to the back side, where there is also the mentioned EGR cooler!! Turbo, catalytic converter....

If there is nothing found, then it will be costly and time consuming 😔

The problem is in the gasket under the cylinder head, as I wrote earlier. It makes no sense to look for another reason.

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.

In these cars with DPF, the seals fail, and after disassembling, it often turns out that the block is crooked and it is not worth doing it. Engines without DPF work.

The EGR cooler is located on the rear of the engine. It can be seen from the canal or on the lift. If the EGR cooler is tight, the coolant will get into the exhaust gas, so it will go into the engine intake and the engine will smoke white. The engine will also smoke in white with a leaky gasket under the head, but here the fluid will mix not only with the exhaust gases but also with the engine oil, so an emulsion ("goo") should be formed under the oil filler cap.

And you say your engine is not smoking at all.

If it is not smoking, why do you choose the failure of the EGR cooler or the head gaskets at all?

The fluid pressure in the cooling system can be measured. Maybe there is a leak in the system somewhere, not related to the radiator, and even more so with the gasket under the head. After all, there is also a pump in the car, it is sealed, and hose connections and seals do not last forever.

Someone advised to bypass the EGR cooler if a malfunction is suspected and see if the situation improves. Some people blind the fluid inlet and outlet from the EGR cooler and only then check whether the exhaust gas appears in the liquid on the test. In Toyota, there is a problem to do this, because the EGR cooler on the one hand has the fluid supplied through the connector (hose), but on the other hand it enters the engine block (a hole sealed with an O-ring). I would try to replace the EGR coolers with another, used, in a certain condition, and only look if there are liquid exhaust gases.

Putting that the head gasket has fallen "because the engines are bad" is like taking thousands of zlotys from someone's pocket without a thorough examination and diagnosis.

This EGR has radiators, but on this engine model it is located at the rear, located under the exhaust manifold.

Hello, I have the same situation.. from what I learned, the sleeve on cylinder 1 drops and this is what happens, but then wouldn't the engine limp? The test for the presence of exhaust gases done once comes out negative once positive.

He will walk normally. Only the fluid comes out

And when it comes to repair, it's cheaper at Toyota service than at any other mechanic, at least in my area

So that they will make a gasket in this engine cheaper at the ASO? What indicative costs are you talking about?

That's what I wanted to do in Szczecin with an ordinary mechanic, they call 8k .. in aso for parts and work comes out 3500 thousand zlotys. Except that they don't do grinding, so I agreed that when they disassemble, they give me the heads and possibly the block, I'll bring them on my own for grinding, and later, when I bring them to them, they assemble. The grinding of the head and block is about PLN 400, so it comes out 4k

Hello, someone knows how to unfasten and where the injection to turn off the DPF burning, I don't mean computer only so quickly manually.

Toyota t25 2.2 diesel 150hp year 2006 Short on topic. I was ejecting fluid even on cold engine when adding gas. Exhaust test positive, immediately changed color. No other symptoms, none apart from a slight loss of power. Mechanic said straight away head gasket, a bagatelle 1200 gbp total with labor and planning. AHA I am thinking and reading this post of yours. I bought the egr exhaust cooler second hand for 17gbp. Fact, it is at the back of the engine. I even bought the car because it was standing and I needed it, I think old Toyota and so need to change. AHA. Now I have two and it drives like it used to 8 years ago. Torperda. I feel sorry to give it away. No engine overhaul until you replace the radiator at little cost. Cheers to all of you, and I don't want to hear about defective engines and head overhauls and that the blocks are also crooked. And by the way, you can't fit a bypass to check it because it is directly mounted to the engine.

Well, just check whether the block is made of cast iron or aluminium.
Aluminium block actually makes no sense to repair.

Hello
I follow the topic, I own a Toyota Corolla Verso 2.2 version 177KM, in my case there is a loss of coolant only when the air intake is set to warm values (consumption of about 1L for about 300 km), when I set cold air the coolant is not lost. 3 independent mechanics have ruled out a head gasket, they have also not found the source of the loss, there are no visible leaks in the engine compartment or in the cabin, the windows do not fog or smell of coolant in the cabin, the car drives normally, no smoke, no slime on the cap or in the expansion tank.
Maybe someone has been through something like this 😫
