2006 Path SE 2WD 4.0 L 4Q40 DE Still overheating. Rad and Reservoir caps were switched. Therm spring on Reservoir and plain ring shaped gasket on Radiator now. Fluid checked several times added and raised front and ran @ 2500 rpm 10 min 3 times. Calsonic sticker on A/C Condenser I think #10010604 2 92100 EA500 A7 A0702002 Calsonic ANSE I NA. No sticker to right of Rad Cap & no Nissan stamped on top of plastic. No debris in fins. Ran on Highway @ 65 mph with A/C on and she starts to overheat so I turned Heat to 80 to cool off. No hoses seem to collapse.With 215000 mi the Guy I got it from got tired of the overheat problem I bought it from him for $2g. His mechanic bypassed the rear heat and said he replaced thermostat. There are worm gear clamps @ firewall on passenger side where it looks like he bypassed rear heater. Spring type clamps on thermometer I wonder if he really changed it. Green antifreeze. What should I check for now?
