Car in question is a 2002 Camry with the 2.4l. I noticed a drop of coolant on top of the A/C Compressor, directly beneath the upper radiator hose to thermostat housing junction. Running my finger around the hose connection itself, it is weeping from there for sure. Hose is original, with 145K. With the age/mileage of the hoses, I planned on replacing them anyhow as this car sees 100+ mile highway daily driving. The question is this- should I start with only the hose, or is it likely corrosion of the aluminum housing is compromising that seal as well, requiring replacement? Based on the very few maintenance records, it looks like it has been over a decade since the coolant has been changed. I haven't had the time to pull it apart yet, but wanted to have all parts ordered and on hand for when I do. Thanks in advance.
