[QUOTE="Messner, post: 159341, member: 4797"] I have a Base 2007 Convertible with the paddle shift A6 on a 6 Liter. Last fall when I parked her I noticed she was starting to run hotter, 230-235 etc. When I pulled her out of hibernation yesterday (Calgary area) I removed the intake and the top plastic panel for the radiator to check for debris (perhaps the most common cause?). With a rag on a stick I removed at least a cup of dirt and sand from the front of the condenser! A bunch was blown out using a garden hose on the Rad & Condenser too. I think I’ll still change the thermostat as it may even be the original, I’m not sure. After putting her back together I went for a drive. 50F ambient temps (cool Calgary April day). The temps on the highway are at least 20 to 25F lower! It even gets down to the high 180’s at times. In town and idling around in traffic it’s much cooler now, well under 210 most of the time and cools off more right after attaining 40Mph (and higher) getting more air into the system. So if you’re having a overheating issue starting to occur, check this first the repair is free!! PS My neighbour helped me to design a sprayer for the end of a garden hose that will fit between the radiator and condenser. It will help for behind the rad and fans too. I’ve yet to try it but know it will help clean these areas. Pics will be available if you need them - it’s a hollow metal tube. The end is blocked off and a small hole was drilled in the side near the bottom to spray sideways. This is attached to a garden hose and will make the job easier next time! :) [/QUOTE]
