Product Description
When a lower radiator hose O-ring fails on certain Chevrolet and GMC vehicles, the dealer often requires replacing the entire hose assembly. This Dorman OE FIX allows direct replacement of just the failed O-ring to save time and money. Please note: this O-ring is engineered to fit only the updated OEM radiator hose on specified vehicles; it will not fit the lower radiator hose that was factory-installed on 2014-06 Chevrolet and GMC vehicles.
- Direct replacement - this O-ring matches the fit and function of the original O-ring on the factory-updated version of the lower heater hose on 2014-06 GM vehicles
- Cost-effective repair - inexpensive alternative to dealership forcing an entire hose replacement just to replace an O-ring
- Application specific - engineered to fit only the updated OEM radiator hose on specified vehicles; it will not fit the lower radiator hose that was factory-installed on 2014-06 Chevrolet and GMC vehicles
- Trustworthy quality - backed by team of product experts in the United States and more than a century of automotive experience
