Review on 🔥 OSC Cooling Products 98004: High-Quality New Heater Core for Efficient Heat Transfer by Robert Pierce

Perfect for my 2000 Superduty 7.3. It comes with foam which is way better than what my local store doesn't have. The foam prevents hot air from entering the cabin. And we don't want that in the summer. Using your old loose foam will definitely cause leaks. Fast delivery and cheap price. One piece of advice when disconnecting the factory heater hose quick connect couplings from the heater tubes: use a 21mm open end wrench as a removal tool. No tools need to be bought. And watch a video or two to understand how to replace the heater core. This saves you a headache. In general, nothing complicated, the most difficult thing is to remove the heater hoses from the old core.
