## Description

GM Genuine Parts A/C System Valve Cores are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These A/C system valve cores are components of the A/C service valve through which your vehicle's refrigerant can be accessed and serviced. The valve core is a spring-loaded poppet valve that is opened when the service technician connects the A/C service machine hose couplers. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Review: Worked fine but pricey for a simple Schrader valve - This Schrader valve worked fine in the low-pressure valve of our GM vehicle, but "genuine GM" is certainly overpriced.
Review: get the best - weep once - I replaced all the core valve when I flushed, cleaned and rebuilt the AC system top to bottom of my trusty Silverado. Her original AC lasted 18 years before she gave her last full measure. The system is at 250 microns na was pressured tested with nitrogen for three days at 120 PSI. Zero leaks and almost a dull roar when everything is perfect and nothing goes wrong. Big tip for long term success: don't use PAG oil to rub the seals and gaskets. You're asking for oxidation/corrosion creep since the aluminum tubes and components are already been thorough hundreds of heat/cold cycles. Aluminum is always oxidizing. When moisture creeps in as the PAG oil absorb moisture you are on borrowed time. I used GM seal conditioner from the R12 days. It was one of the best conditioners ever made. I fully expect another 15 plus years on the new AC system. Also, when you have the vacuum level you want, load coolant liquid from the high side. Easy to do and gas laws and fluid physics are in your side for a precise and controlled charge cycle. I may post picots of the setup is made up when using this punky little R134a 12 ounce cans. Also, don't pull a vacuum if you can avoid it using those manifold setups. Seperate vacuum and separate charge lines. Just some advice FWIW. It pays to do your homework and be a winner. Peace.

## 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.

### ⭐⭐⭐⭐⭐ pricey but works
*by G***2 on June 2, 2025*

this fit in the low side fill port of a 2015 gmc sierra 1500, as indicated. it looks awfully similar to the extras that came in the generic stem tool kit that cost about the same as this one valve and had many parts, but it did fit as indicated, and it seems to have stopped the leak at that location. not sure the price was worth it since i also had to get the kit with the tool which had valve stems in it too, but this does work for what it was supposed to do.
