On my old Subaru Liberty & Forester ECON would cut out the compressor if any medium- heavy throttle application was applied so putting less load on the engine
Also would put the system in recirculate so it would ease the load on the aircon
If you put a dial indicator on the end of the input shaft spiggot that would tell if its bent. The bearing surface looks chewed out near the end. Also looks like your spiggot bush has been spinning whick is not good
Im about to put in a new koyo radiator and during my research came across Red Line Water Wetter
The claims and reviews give it decent thumbs up, naturally I bought some as an option
Anyone able to vouch for it?
