Review: Genuine OEM Replacement - Vehicle: 2011 GMC Canyon SLE I5 Genuine OEM replacement. STAY AWAY from the Dorman or equivalent parts as they rely on flimsy plastic tabs to snap on to the heater core. They are also difficult to remove because you need to get a removal tool behind it. In my case, there was not enough clearance for a tool and I had to cut it off with a Dremel. This replacement part uses a retaining clip to "snap on" to the heater core. The clip is easy to remove and has a much better fit than the plastic tabs. The seal also seems of higher quality. I very much recommend buying this replacement part.
Review: Works as a replacement - So why GM designed this brittle plastic thing like this, who knows. I guess, to create a sacrificial weak point to fail instead of the heater core. As a quick replacement for a part that almost no one carries in stock, good option. It is easy to fix yourself if the hose is in good shape.

## Questions & Answers

**Q: How does my vehicle’s AC system work?**
A: The AC compressor pressurizes refrigerant gas, which moves to the condenser. The gas releases heat, condensing into a high-pressure liquid. After cooling, the liquid passes over evaporator coils to cool the air as it is blown through the vents.

**Q: What are the signs the system needs service?**
A: Common indicators of an air conditioning system in need of service include warm and/or weak airflow through the vents, frequent on/off cycling of the system and a strange or musty odor.

**Q: Is the puddle of water under my car a sign of AC problems?**
A: Not necessarily. Condensation typically builds up on the AC evaporator and the water is drained at the bottom of the vehicle. That’s normal, but a larger puddle combined with reduced AC performance could indicate a problem.

**Q: Does low refrigerant mean there’s a leak in the system?**
A: In most cases the answer is yes. AC systems in older cars will experience refrigerant leakage over time, but a later-model vehicle that needs continual refrigerant recharging typically indicates a leak.

**Q: Can a new cabin air filter improve AC performance?**
A: Yes. A very dirty or clogged cabin air filter can reduce the airflow of the AC system, reducing its cooling efficiency and making the system work harder than normal. Periodic cabin filter replacements help the AC system keep its cool.
