MY 2004 DEVILLE is losing antifreez, and I am putting more in tha car every 2 to 3 days. can anyone give me some advise as to what could cause this problem and how I could fixe the problem or where to start.
Check hoses and clamps, see if you can rent a pressure tester from autozone -- if not you can buy one pretty cheap online ~$50 from amazon and no adapter needed. You can also use UV dye to track the leak. I'm going through this myself and its so cold out i'm taking both approaches. Pumping the system up trying to find the leak in the dark (when i get home) or in the wind (on the weekends) is not easy, so UV dye could also be an aid. UV dye is on amazon too, that's like $4. Buy a UV flashlight and goggles too.
