2 PCS Heater Inlet Hose Fitting, T-connector Three-way Cooling Water Pipe Joint, Original Replacements, Compatible with Select Cadillac/Chevrolet/GMC Models 15055343 15055342 (Black & White)

One of the fittings in my 2010 Tahoe has had a very slow leak since I bought it, but I never got around to replacing them. Saw these and ordered them and the first thing I did when I received them was replace the old ones.These fit perfectly, though I did use some dielectric grease to ensure everything slid and snapped together easily without damaging the o-rings.Filled the cooling system and pressure tested at 15psi for about an hour and nothing was leaking.Very happy with these so far and look forward to not having to add coolant every oil change.

It's hard to tell if these are going to last since even the factory ones break pretty often. Overall though they look like their well made and thick walled. For the price it's for sure worth a try. Do yourself a favor and change them if your working on your cooling, even if yours are not currently cracked.

just pay the extra for D@$#¥n or GMdon't waste your time, energy and antifreeze.
