Hi
I followed the great walk though my T J G to replace the thermostat on my golf 1.8t AGU
a of bit difference. But when I took the thermostat housing off there was no thermostat

so I put the new one in then I put the o ring on and then the housing but I think I have put it in the wrong way I think it should have been o ring then thermostat then housing

. I took it for a run and it went to 90 and stayed there and I checked it and it dose not leak.
