Peugeot 306 Rehears with a new joint and lid

Thank you very much Tessy, Kikemec and all for the aid. For me it is very important to share and listen to experiences with cars. Women know about cars like portfolio men !!

Hi Natylesca.

The reference to water is a very interesting issue that you have touched, and I mean the liquid that you are putting the cooling system.
As you know, there are several types or classifications of water, according to their sources. There are harder, soft waters, etc. A hard water is what is considered to have more lime and other elements that make it more difficult to treat, it requires more treatments so that some materials do not damage much.
Soft waters are somewhat more pure, loss of lime and other heavy substances.
In some countries, hard water, which usually contains high percentages of lime, forms a whitish scab in the cooling ducts of cars engines, which obstructs (it is like cholesterol in the veins) the ducts. For this it is necessary to clean the systems. But even better, it is not to use common tap water because it is usually very harmful to the ducts. I corrode, the pica, cavitation problems in the water pumps, etc.
It is very possible that the origin of your problem is even: tap water.

Hello people, I tell you that the car was seen this morning and no longer heats up. Now, I tell you that I brought a role with several recommendations that you gave me, saw it and tells me that what I had was air in the radiator duct and made the radiator purge. The truth is that I tried a long section and does not heat. We see how long it lasts so I still did not change the radiator lid or hoses or anything. I did not get the lid here (here is re complicated ..). I'm going to try it for a few days and then I will let it go until I get what is necessary. Then any change warns you, thank you all for the time to answer doubts.
