U definetly have air in the system...Turn engine on and open up OBC in your cluster. Open #9...#9 will show your temperature...turn heater on to 90 degrees ..Open hood and unscrew the vent screw loacted by the expansion tank... Car will idle to about 100 to 105 c
..You will see coolant bubbles escape the vent screw... Now with your hand reach the lower radiator hose escaping the passenger lower side of the radiator.......feel the temp by hand..if it is COLd.. the Thermostat has NOT open up........Kepp bleeding until that hose starts to feel warm or HOT...once hot then the thermostat has opened up and coolant is NOW flowing thru ur sstem corrctly....and Now tighten up the vent screw and ur DONE!@!!!!!
