Fix the design defect they refuse to fix yourself! - Gas trucks-**See Photo 4**Install the valve at the water pump on the front of the motor on the heater supply hose. Find the hose labeled "Eng Out" and remove it. Install this valve to the hose you removed and connect the supplied hose to the valve and the water pump. Install clamps as shown in the photos. Top off coolant, you will lose some when you initially removed the hose from the water pump. - Diesel trucks- **See Photo 5** Install the valve on the heater supply line above the turbo. See Photo 5 to determine exact location to install the valve. Remove the heater supply line from the black tube coming from the motor. Install this valve to the hose you removed and connect the included hose to the valve and black tube and install the clamps as shown in the photos. Top off your coolant, you will lose a small amount when you remove the line. - There is a known defect in these new trucks. The blend door in the dash allows hot air via the heater core into the HVAC system when the AC is on. There is a service bulletin to address this and it requires them to rip your entire dash out to replace the HVAC system. I guarantee you will have damage and problems down the road if you allow them to do this plus there are many reports that it does not even fix the problem! This is an easy fix that is guaranteed to make your A/C blow 8°-15° cooler! - This kit installs in minutes without making any permanent mods to your truck. It is 100% safe for your truck and won't cause any damage or Engine Lights. This kit is comprised of premium components that will not fail. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B092YVQS7K | | Best Sellers Rank | #21,317 in Automotive ( See Top 100 in Automotive ) #11 in Automotive Replacement Heater Blend Door Levers | | Brand Name | Muzzys | | Color | Black | | Connector Type | Clamp | | Customer Reviews | 4.5 4.5 out of 5 stars (371) | | Item Weight | 16 ounces | | Manufacturer | Muzzys | | Material Type | Metal | | Model Number | 10377 | | Number of Pieces | 5 | | Set Name | True | | Size | 0.625 inches | | Thread Size | 0.63 | | Thread Type | NPT | | UPC | 600599657694 | | Unit Count | 1 Count | ## Product Details - **Brand:** Muzzys - **Color:** Black - **Connector Type:** Clamp - **Item Weight:** 16 ounces - **Material:** Metal - **Number of Packs:** 1 - **Number of Pieces:** 5 - **Size:** 0.625 inches - **Thread Size:** 0.63 - **Thread Type:** NPT ## Images ![A/C HACK KIT Fits: Ram 2019 2020 2021 2022 1500 2500 3500 Trucks with Weak/Warm Air Conditioning from Factory, Heater Core Blend Door By-Pass Mod Fix, W/Clamps Hose Shut Off Valve, Gas & Diesel - Image 1](https://m.media-amazon.com/images/I/31CFn2nDUFS.jpg) ![A/C HACK KIT Fits: Ram 2019 2020 2021 2022 1500 2500 3500 Trucks with Weak/Warm Air Conditioning from Factory, Heater Core Blend Door By-Pass Mod Fix, W/Clamps Hose Shut Off Valve, Gas & Diesel - Image 2](https://m.media-amazon.com/images/I/61cuVi4-VpS.jpg) ![A/C HACK KIT Fits: Ram 2019 2020 2021 2022 1500 2500 3500 Trucks with Weak/Warm Air Conditioning from Factory, Heater Core Blend Door By-Pass Mod Fix, W/Clamps Hose Shut Off Valve, Gas & Diesel - Image 3](https://m.media-amazon.com/images/I/61cBGXRusyS.jpg) ![A/C HACK KIT Fits: Ram 2019 2020 2021 2022 1500 2500 3500 Trucks with Weak/Warm Air Conditioning from Factory, Heater Core Blend Door By-Pass Mod Fix, W/Clamps Hose Shut Off Valve, Gas & Diesel - Image 4](https://m.media-amazon.com/images/I/91eFve-9dQL.jpg) ![A/C HACK KIT Fits: Ram 2019 2020 2021 2022 1500 2500 3500 Trucks with Weak/Warm Air Conditioning from Factory, Heater Core Blend Door By-Pass Mod Fix, W/Clamps Hose Shut Off Valve, Gas & Diesel - Image 5](https://m.media-amazon.com/images/I/91HCn5HujHL.jpg) ## Frequently Bought Together - MUZZYS A/C HACK KIT Fits: Ram 2019 2020 2021 2022 1500 2500 3500 Trucks with Weak/Warm Air Conditioning from Factory, Heater Core Blend Door By-Pass Mod Fix, W/Clamps Hose Shut Off Valve, Gas & Diesel - BOSCH 6090C HEPA Cabin Air Filter - Compatible with Select Ram 1500, 1500 Classic, 2500, 3500, 4500, 5500 Trucks - FRAM Extra Guard CA12375 Flexible Replacement Engine Air Filter for Select Ram 1500 Models, Provides Up to 12 Months or 12,000 Miles Filter Protection --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/320969224-a-c-hack-kit-fits-ram-2019-2020-2021-2022](https://www.desertcart.in/products/320969224-a-c-hack-kit-fits-ram-2019-2020-2021-2022) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-07-31*
