My mx 5 aircon failed on yesterday. Heard hissing sound and I suspect the cooling coil is leaking. The mileage of my car is only 25k and is still under free servicing and warranty. Called Mazda service centre to check if the aircon is under warranty. Give her my car number and told her that I suspect the cooling coil is leaking. She told me is under warranty and I arranged to send my car for repair at the Tanjong Penjuru Centre today. Arrived in the morning, spoke to the SA. He too suspected the the cooling coiling is leaking. He told is that is covered by warranty. Left my car then and went back. The SA called me after an hour to two to tell me that the cooling coil and O rings need to be replace. The warranty only covers the aircon compressor but not the cooling coil and I need to pay around $1200.00 for the repair. I told him that I never encounter or know anyone who need to replace the cooling coil at 25K mileage. It is very obvious the quality of the cooling coil is questionable. And it is a parts that cannot be purposely damage by user. I done all my servicing with Mazda because it is still under the free servicing package. Told the SA to get his manager to contact me. Is a shame that the staffs are trained to prioritize profit rather than reputation.

Yes. I did it !!! I ownself repair my car aircon - Change Evaporator (Cooling Coil) ($130), Discharge Hose ($45) and Compressor ($230). I bought new tools like Manifold Gauge, Quick Release Connector and 1/2" ACME Valve - $50, Vacuum Pump - $130. It take about 1.5 day to replace the Cooling Coil and 4 hours to replace the Compressor and Discharge Hose. Yes, you can buy these small canister and ownself fill up. But, how much to fill up ? For my case, my car need 680g of 134a - 2 cans. Kaltech Engineering & Refrigeration Pte Ltd 9 Tuas Link 1 Singapore 638587 www.kaltech.com.sg - They sell 340g 12oz canister to 13.6kg cylinder to 20000 kg 134a Refrigerant. As for Manifold Gauge Set - www.aliexpress.com Compressor - www.aliexpress.com For Original KIA part - Buy Korea @ www.koraps.com The repair is quite extreme and very labour intensive. I don't recommend you do it, if you never even ownself change a serpentine belt before. I even added a tracer oil so the next time it breakdown (touchwood) I can trace the leak with a UV light.

Hi. My car having a chemical/gas-like smell when entering the car before even start-up. This smells is worst during morning when first open car. Seems like no oil leak. Went to two workshop, they say most likely is cooling coil problem. Need to change the coil which cost quite ex. I abit not comvince as they only told me this solution by hearing my problem and smell. Cos i understand that for cooling coil, there's no way to check from exterior. So wondering is there anybody else having the same problem before or isit due to others problem? Before i proceed to replace the cooling coil which i dunno whether isit the cause of the problem. And I hd just change a new conpressor and filter a mths ago. Thanks.
