The water inlet housing connects the radiator hoses to the thermostat. For certain applications, the water inlet contains threaded holes or ports for sensors and switches. These original equipment engine coolant thermostat/water inlet assemblies have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Review: Not the correct part for my 2014 chevy impala 2.5 4cyl
Review: Used on my 2014 Cadillac ATS4 2.0T. Was quoted over $1,300. Did it myself for just over $100. Helped my car stop overheating. Pretty easy to change out. For the ATS 2.0T, you don't NEED to take off the turbocharger; having smaller hands helps. If your car still overheats after, check the coolant temperature sensor to see if that needs replacing too.

## 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.
