water reduction - 407 - Peugeot Forum

hello friends. my vehicle is 407 2007 model 1.6 diesel executive black. 2 weeks ago, I felt the need to open the hood and check the place where I went short distance. It was very hot and the temperature seemed to rise a little faster than usual at that moment. Anyway, when I opened the hood, I had the crankcase protection sheet installed at the bottom when the original broke. There was a drop of water on the left side of the sump housing as I could see it through the crack. flush under the belts next to the engine. I immediately called the master. "Wait for the car to cool down, add water, come here," he said. After 15 20 minutes, I opened the lid and added 1.5 liters of water and went to the master. The temperature did not exceed 90 until he left. The master opened it and saw the drops. We looked at the water, it was not diminished until it was gone. anyway, there was a road with a long steep slope, we took it there soon. We tried the tool there and forced it. there was no increase in temperature. were within normal values. After climbing the slope, we stopped at the appropriate place and checked. The droplets were still there. To make sure there was water, he touched his hand under the vehicle. it did. he said that there is only circulation in that area. it's throwing it out of circulation. it can't be anything else. There is a radiator-clogging chemical, let's throw it out. If it does, keep it like this for a while. He said if it doesn't cut, I need to look there. Anyway, we put it, I bought it and went. At first it seemed like nothing was happening. Then I traveled about 200 km and when I checked, the water was reduced again, around 1.5 liters. I went back to the master. no drops were visible. this time they connected a pump with a cover to the reserve tank and created pressure. there was no change in pressure or there was no flow from somewhere. We waited for a while, there was very little change in pressure. They said he could escape through the cover part too. I haven't done anything to the car yet, but I'm thinking of taking the car tomorrow morning. I was going to a different master last year and because that master couldn't solve the overheating problem, I had to make two covers. The problem was that the 2nd stage of the fan was not working and that's why it was overheating. I took it to the service and found it and now I made the transition to my master. Has anyone experienced something similar to this? what should I do? The heat situation absolved my last summer and my economy. 5-6 thousand money gone in 2 months with other malfunctions. I don't want to be in the same situation now. If I continue to use it like 1.5 liters of water reduction, it will definitely cause a problem. I'm too bored. It's constantly causing problems. I hope you can help with this.

First of all, get well soon

Your master didn't say let's change this and that right away, this is good news, trust whatever the master says because I think many masters want to change things right away

I say listen to your master and focus on circulation because you can't live with the fear of burning the engine or gasket

Thank you sir. I went today. first, I took the car to around 80-90, made a short lap and went up a couple of steep slopes for a short time. I also turned on the air conditioner. I turned and lifted the vehicle, it was still on the lift. The air conditioner continued to work. We went and looked at the bottom, nothing is visible at first. While we were looking around the circulation, water dripped onto the master's hand. it turns out that the water I was talking about was the water coming from the pipe of the air conditioner. If I told you to concentrate on the pipe, I didn't know if it was leaking, it was dripping a little from there, from the top of the pipe and from the connection. the pipe was cold already because the air conditioner was running. Since he said that the engine cooling water had nothing to do with the cooling of the air conditioner, he did not take any action on it. it was going under the car which I think might be the drainpipe. The master said it was not relevant. Afterwards, I said that I heard a hissing sound from the lid once, but I wasn't sure when I looked. I told this to the master. This time we thought it might be from the cover and I went and bought the original cover for 40 liras. We shut it tight. I will follow again for a while. no traces of oil in the water. When we check the oil, there is no abnormality in it. If it was about the gasket or the cover, there would probably be a change. still, my eyes are always hot, but the values are always normal. Very rarely, 90 goes down to 90, but in normal long-distance driving without traffic, it is usually just under 90. Let's see, I hope it doesn't cause any problems. I'm tired now.

I hope you can solve it soon bro, I have 307, it can cause problems that we can't find, but there is nothing we can do in this market, we need to know the value of what we have 😂

thanks a lot =)

followed the car. I have traveled about 200km and the water has decreased again. I didn't have time to add to it at that time, but it went down a level close to 3 fingers from the line. I just realized something like this. When I checked the water level of the vehicle, the car had last run a day ago and when I opened the lid, it hissed for a very short time. Does anyone know if this is normal or not?

I didn't run the air conditioner to check if it was a condition connected to the air conditioner. Although the air conditioner is not working, the amount I mentioned has decreased on the 200km road. There was water flowing from the pipe at the level of the alternator towards the bottom of the water tank. it was dripping. the place i mentioned at first. I wonder if that pipe is related to the air conditioner? how can i find it is it related or not with coolant? As I said when I said the bottom of the water tank, the pipe at the level of the alternator was not coming from the water tank anyway, as far as I can see.

what else could be the reason, friends? Any suggestions?

Also, check the bottom of the gas pedal and even the driver's side of the car, maybe it's kicking out of the honeycomb.

I don't know exactly where the honeycomb is at 307 and 407, I may not have misled you, but you can have the honeycomb checked

I checked the carpet and there was no wetness or humidity. Do you need to check internally?

No, even if you look inside, the carpet would be wet if it was in the place I call honeycomb. You said 1.5 liters, it's not less

They are throwing colorful things into the water for these leaks, have you actually tried it?

Master do it but you don't try 😅

Okay, I'll tell the master tomorrow that there is such a thing so we can try it. We have thrown a radiator leak plug before, I hope it doesn't cause anything else. :D They wrote that it can cause blockage when they searched a little on the internet.

It's been a long time since you opened the thread. I hope you have solved your problem. I'll add it in case it might be helpful to another friend who has a similar problem. For your information, 407 thermostats will also be among the top 5 perpetrators of water leaks. It has a PC plastic enclosure that includes the temperature sensor and the thermostat. The thin gasket where it connects to the engine starts to wear out over time. Happened to me twice. One of them is when I first bought the car 5 years ago (then the thermostat was working well at that time, it was leaking from the gasket in the flange section) and the other 1 week ago as a result of my thermostat malfunctioning (which this time was leaking from around the sensor socket, not from the gasket). I recommend you to check the thermostat in such cases.

Let's take a breath and try it. it had happened to me.

Hello after a long time. because a small piece was left in one of the piston chambers of the vehicle (probably my old master had rectified it. I think it was one of the series of events that developed because of him.) the cover and piston were gone and the vehicle made raucous noises on the road, smoked and fell out of performance; It came out when I pulled it in front of the house and took it to my new master with a hammer since I was close to home. Of course, I had to build a motor from scratch. parts that could be changed. renewals have been renewed. The reason for water reduction occurred during reassembly. The first thing to notice is that there is a break in the recirculation rear pipe. the second one, a piece called the exhaust gas exchanger was rusted on its edge and water was leaking from there. I hope it doesn't happen to you in the future. If it comes, it would be useful to have these checked as well.
