## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great hose assembly
*by N***L on May 11, 2024*

Good items works great

### ⭐⭐⭐⭐⭐ Heater hose assemply for LT1
*by H***8 on May 17, 2025*

Exactly like the original hose assembly!

### ⭐⭐⭐⭐⭐ Replacement for 1996 Impala SS (LT1)
*by S***C on December 7, 2018*

I used this kit to replace the primary water pump heater hoses and the associated t-fitting and flow restrictor in my 1996 Impala SS. The kit also includes the reservoir hose from the t-fitting to the reservoir. The product seems to be of reasonable quality, comes with several crimped on connectors (to the t-fitting and restrictor), several lengths of hose are covered with conduit for protection, and there are even a few spring-clip style hose clamps as part of the package. I do not think these are 'original' quality (they are clearly marked "Made in China") but the it is likely the highest quality new replacement available for these old cars...
