I had a 51 at the cabin that a mouse got in the block and it never ran cool ever since,it was not worth tearing apart due to the motor being very tired and the truck was rough and I ended up giving the truck to someone down the road before the property was sold. We could not keep radiators in our lot trucks up there when we were not up there since the radiators would disappear and I forgot to plug up the motor. Jeff
