Well we were doing some maintenance on the Cruiser tonight in preperation for a 3.5 day excursion to a remote Indian Village at about 2500 meters in central Mexico. The remains of the road is 150 km and we aren't sure if we will even make it. So in preperation I decided to drain the block and change the antifreeze, and install a new fan clutch. The fan shroud was removed and when my amigo installed it again----a long bolt was used instead of the neccesary short version--it was me that handed him the long version used for holding the protection plate on the bottom---You guessed it I have a 10 mm hole right next to my fill cap. So can this be patched or is my 1 year old new plastic $450 radiator done for? If it is done for I will try and source a metal radiator before my trip. Or I won't go on the trip at all.... Thanks for your thoughts.
