ENGINE AND ENGINE COOLING - COOLING SYSTEM - HOSE
04/18/200415000309/10/2003
 My hose that connects to the engine to the radiator has cracked at least three times in the past two and half years, i have ask chevy on each occasion that i had to purchase it from the dealership, if there is a problem with how the hose is position so close to the exhaust pipe with no support to keep the hose away from this pipe that gives off so much heat, i truly believe this is creating the problem and i'm tired of replacing it and would like to get to the bottom of this. *jb
