Hose clamp on hose at coolant reservoir lower connection failed. Vehicle had 1,935 miles on it. Hose clamp was either defective or over stressed at installation when truck was manufactured. This failure resulted in a rapid loss of engine coolant. Vehicle was stopped prior to overheating due to driver noticing that vehicle was having difficulty maintaining normal engine temperature based on temperature gauge indication. Warranty repair replaced clamp with screw type hose clamp. All other engine coolant hoses use similar factory installed spring type clamps. Currently no other problems exist.
