November 21, 200916 yr Author Maybe swap out an ECM from a u-pick salvage yard... I just put in a ECM from a salvage yard. I let the car idle for a while and the fans came on. They weren't turning on at all before, so I think this has fixed the issue. Yay! My coolant leak is definitely getting worse and it's coming from the radiator. I've put a new cap on. If I rev the engine you can see it come out of roughly the top center of the radiator in a forward stream. I think the next step is to replace the radiator and see how everything comes out. Does this sound right?
November 22, 200916 yr Glad the ECM swap worked out. Replace the radiator and hoses. Fan screws are likely to be rusted and seized, get a new set of 10mm stainless screws. Bottom fan screws only need to be loosened if the fan housing is slotted. Use an OEM thermostat (no aftermarkets) and gasket, use distilled water when you fill. Fill through the top hose, slowly to minimize air pockets. Burp the air out. Here's the basic procedure, lots of good variants around, but this will get you started. http://www.ultimatesubaru.org/forum/showthread.php?t=66821 Edited November 22, 200916 yr by 89Ru

Burping seemed to go all right. I'll keep an eye on it for a while. At this point, the fans are working and there are no external coolant leaks. Thanks for the help.
