Hi, I was wondering if anyone has had or is having this issue, the water flange on my 91 VW cabriolet keeps breaking. I've taking it to the machanic and he tells me there is nothing wrong with the car it runs fine he he can't understand why it keeps breaking. I have tried everything and I want to fix the car because there are no other major problems, but i have not been able to figure this out, any suggestions and help would be greatly appreciated.

What are you referring to as the "water flange"?

Hey, I just changed the water flange on my sons cabbie . I used the permatex blue rtv sealant along with the o-ring or gasket . Maybe the bolts are being tightend too tight.

Mine does the same thing. it's the Plastic hose flange on cylinder head. I replaced mine 3 times still happening, it gets warp or melting, I don't know what else to do. my oil temp light goes on too but if I step on the gas it goes away. I change to different oil (10W-30) I replaced all coolant temperature sensor,timing belt, water pump, thermostat will be replacing oil pump now.

I had the same problem. I used an autozone part and then a Napa part both failed. I got the vw oem flange and have had no problems.

the problem is not the flange you have a block heater hose from the cylinder head to the heater system. there is a metal pipe thats attached to the cooling system take it apart and make sure nothing is clogged

look to see if when you install the stat , that you get it in the correct postion .."centered "n the housing , or what happens is that you end up tightening the housing down with the stat lopsided in its housing causing stress on the housing ..or doesn't bolt up flat and it will surely break ..plastic parts ..however most of the time i have seen this done, usually you also would have a coolant leak ???
