Thank you all.... In fact there was a misture in the radiator.... from now I will replace 100% of the liquid (22 liters) from mix to coolant (green or pink Peak - https://www.peakhd.com/product/peak/automotive-antifreeze/ ) And observe with attention the variation of temp in the car in different conditions. When it reaches more than 95° celsius I will stop and investigate more. I dont have vaccun equipment in the city I live so I will add new coolant in the tank and when the car heats and pump acts I get the return hose (number? out till purge all old water in the system. When new coolant starts to leave the return hose I stops the car and reconnect in the tank. Latter I tell you the results... Very glad! Hugs

Yes, some times hits 100-110 in certain conditions? traffic jams in hot days (35°) Maybe something is wrong in the car and this is why tank damaged two times But everything seems work... Mystery machine!!! Better investigate ?

Deenses , Thank you very much to send the squema above... I am going to install the new tank and make a double checking in the tubes (some weeks seemed well). As good coolants are very expensive I am going to put demineralized water, go working with the car for some weeks and observe temp and leaks. If everything OK, I replace to coolant. What do you think? any risk to tank damage again? Normally the temp reaches 110 ceusius into the jam and in a road around 95... Doses it seem ok? Puley, pump, fans, termostat,... seems to work OK. But I cannot ensure 100%. I prefer think in a material trouble in the tanks. If there is any other issue I cannot see. That will be difficult to me. ? Marcio

Some people said this component already blowed up So this is my suspecting over some material problem. But don't know if others components could cause this kind of incident too.

Hello Deenes, Aways chek the level and use water with some adctive to avoid corrosion intead coolants (is this a problem?) About second question: the two past tanks had problem in the same area... behind the tank side near of the body's car right in the junction (imend) of the two parts (up and down) of the tank. Seem the component the building process seems to be two parts embedded and glued

Hello guys, I have a Cayenne S 2009 and this car already damaged two water tank. Could any of you tell me if it is a material problem or something wrong in the car that I should work around? The first water tank was an original component (started to leak when car hot), than I bought an used one that damaged 3 months laters. Now I bought a new one (not original /OEM) from this vendor and will fix the third time same problem in the same component. https://produto.mercadolivre.com.br/MLB-1084039426-reservatorio-de-agua-vw-touareg-audi-q7-porsche-cayenne-_JM An I am afraid to damage this one again. Any idea or recommendation? The car has no leakages till now, water level aways OK, and pump seems to work normal. Maybe lack of look with the other 2 tanks. Thank you in advance! Marcio
