GU Radiator Fault

Last weekend I was about to leave for Darwin and checked my vehicle. I found that my radiator was leaking.

When I removed the radiator I found that there are two lugs on the cowling. They had worn holes in the radiator.

I took the radiator to Darwin and spoke to a Natrad gentleman there who informed me that it is a common problem. His advice was to cut off the offending lugs.

For me it was an expensive and time consuming way of discovering this fault. I have submitted this post so that others may not have similar or more serious problems due to this fault.
