## Questions & Answers

**Q: Will this product work on a 2015 ram 1500 ?**
A: The vehicle should have a tag under the hood which tells you the type of refrigerant to use. 

I’m guessing a 2015 does not take R1234YF.   More likely it takes R134.

**Q: Can I add after freon?**
A: this is a stop leak with freon. yes, freon can be added at any time.  you have to be careful not to overcharge this system.

**Q: So add this before the refrigerate, won’t this take up “space” and reduce the amount of refrigerate the system can take?**
A: Yes add this product first and then add refrigerant. This product is safe to use with any R1234yf system.

**Q: I understand that this product stops leaks but is it also a refrigerant?**
A: Yes the stop leak is also in the freon.  Count  the weight in total of system charge.

### ⭐⭐⭐⭐ Can of R1234 is one-time use and Hose is only for use with Stop Leak R1234
*by W***O on June 17, 2023*

The Stop Leak R1234yf system comes with a can of Stop Leak and a hose for connecting the can to the low-pressure side of R1234yf systems. If you are familiar with recharging AC systems, you'll find this system reasonably priced and relatively easy to use. I decided to give it a try and, after separately adding R1234yf my system, my AC system has been working and blowing cold for a month. Three things to keep in mind are: 1. This is Stop Leak and not R1234yf fluid for recharging your system. 2. Although the hose has a valve, the valve pierces the can, so you have to plan on using the can up, or throwing-away what doesn't get used. The hose is specific to cans of Stop Leak and will not work on cans of R1234yf fluid. 3. Plan to still have to add R1234yf fluid to charge your system. Get a system with multiple cans of R1234yf fluid and a hose with a gauge so you can see how much pressure is in the system. My story: The R1234yf AC system on my 2016 Honda Civic suffered from a slow leak that got resolved through periodic recharging. (The charge tends to last the whole season, maybe two.) My Honda dealer said they replaced most of the system (except two hoses) and, although there are documented factory issues, are no longer warrantying repairs. They want over $1500 to replace the two hoses and charge the system. R1234yf is expensive but I figured for less than a couple hundred dollars a charge can at least buy myself a few years by recharging the system myself. Hoping that where I have such a slow leak, this will be a permanent fix...so far, so good. Note: The Honda AC System has sensors to prevent compressor operation if pressure is too low, OR if pressure is too high. If it is too low you will need to put a jumper on the respective contacts in the fuse block to operate the pump. If pressure is too high, you will need to bleed some gas to allow the fluid in the can to pass into the system.
