I have 1999 GMC Sierra 2500 4x4 with a 6.0 (LQ4) and an Auto (4L80e). The truck has the trailer tow package on it with an engine oil cooler built into the radiator and a Trans oil cooler built into the radiator also, plus an additional front mounted factory tranny cooler. I’m tired of the hard lines and GM quick connect fittings leaking (Both have been replaced before). Does anybody make a hose kit conversion, using the factory coolers? Or can anybody at least point me in the direction of what parts I need to adapt the radiator, engine, tranny, and the front cooler over to AN fittings?
