Buy the solvent spray kit to go with it and you will be happy with the results, if you do it right. My AC system is completely clear of any old refrigerant, oil, and any debris from a failed compressor. ### ⭐⭐⭐⭐⭐ Works Fine *by K***S on 13 June 2022* I just flushed the lines and front Evap Core from a 2010 Dodge Grand Caravan. Fluid cleans well and evaporates fast. Evap Core was plugged, this flush broke through the plug very quickly. I didn't get any residual oily film like other users have reported. It did the job it's designed to do and did it well. ## Frequently Bought Together - Mastercool 91049-128-4 Black/Yellow Flush Solvent, 4 Pack (1 Gallon) - Mastercool 69900 "Mastercleanse Flush Machine, 1 Pack - Mastercool 69925 Multiple Flushing and Leak Test Adapter Kit for Flush Machine, 1 Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.my/products/363287177-mastercool-91049-32-6-black-yellow-flush-solvent-6-pack](https://www.desertcart.com.my/products/363287177-mastercool-91049-32-6-black-yellow-flush-solvent-6-pack) --- *Product available on Desertcart Malaysia* *Store origin: MY* *Last updated: 2026-08-13*
