Review on TYC 96011 Replacement Heater Core by Jerry King

Error for 15 minutes. It fits perfectly, however I have noticed that the supply and return lines are a bit loose at the connection to the heater core. Plugged everything in, tested for a few minutes, and everything worked fine at first, but after 15 minutes, coolant from the intake line started spraying over the passenger side of my truck just minutes before I was about to put the heater core cap back on. . The leak was at the junction of the intake manifold and the heater core. I will return it as soon as I can get an OEM replacement. It's a pity to drain the coolant again.
