Sonnax Cooler Line Repair Kits

Sonnax cooler line repair kits allow case salvage without transmission removal. A common complaint in late-model Chrysler rear-wheel-drive units is a cracked and/or leaking case caused by installing the cooler lines. The tapered threads and the lack of a stop on the OE cooler line fitting can load the case and create a fracture, resulting in leakage that may require replacing the case. Sonnax kits feature adapters that seal on the leading edge, preventing fluid from reaching the fitting threads and crack. The fittings have straight, not tapered threads, to prevent the crack from spreading. A special tap tool for case threads is also included in the cooler line repair kits.
