Is your Jeep's AC blowing warm air? This AC Compressor with Clutch is made to fix that! It's a complete unit, pre-filled with PAG 100 oil (about 180ml), so you don't have to worry about adding the right amount. Fits Jeep Grand Cherokee 4.0L from 1999 to 2004, and Wrangler 4.0L from 1999 to 2006. Also replaces a ton of part numbers like CO 22034C, 1521290, 1022034, and many more (check the list!). The compressor type is 10PA17E, uses R134a refrigerant, and has a 6-groove pulley. Important: Before you install this, make sure to flush your entire AC system and check that the condenser is clean and working. A dirty system can kill a new compressor fast! Once installed, it runs steady and quiet, cools efficiently, and can even help with fuel economy since it's designed for lower load. Get your cold air back and survive the summer in your Jeep!
