well, went for a test run today with the PATCHED rad and the Geo Metro fan sorta temporarlily installed... never had to turn the fan on once. this was with the kia fully loaded and towing a trailer. the patch on the rad held and once it warmed up it never got over the normal mark on the gauge. guess i'll just run it like this for a while and when it starts to warm up we'll see what the metro fan can handle.
