Has anyone else had any problems with the URO components. I replaced my original coolant expansion tank with one from URO about 2 years ago and finally found it was leaking around the seam between the tank’s bottom and top. It was a slow leak and now I wish I had left it alone. My new replacement tank has/had an issue with the cap. It became really tight before it “clicked” and then leaked like a waterfall. I found a very similar leak in a forum post/clip provided by Tony_Likes_Going_Fast_XJ8: ( https://youtube.com/shorts/ewSBy1o2VAE?feature=share ). I replaced the URO cap with the original one from my initial tank and it goes on nicely, does the 3 clicks right away and seems right. However after running up to temperature it also leaks (drops/drips not a river) so now I am wondering if the tank itself is the issue.

Also a question regarding the lower radiator hose. I ordered one from SNG that was a “repop” (at the time they did not have a Jaguar one) and it turned out to be a URO. It has hand written numbers C2C9778 which are supposed to be correct. However the outside diameter of the hose is the same as the diameter of the radiator outlet/inlet. It might stretch over my new replacement radiator but I feared it would cause my original radiator to crumble. Especially since the inlet for the upper hose is already crumbling. The upper replacement hose slipped on nicely and was an original Jaguar branded hose. My car is a early 2004 model with a build date of April 2003 but I ordered a hose that should have been right. Surely they do not all have to stretch that much to fit.
Any others have issues with any URO parts?
