The 3.5L 2GR-FE V6 of late model Toyota and Lexus cars and SUVs can be tricky to bleed of air after coolant replacement. Toyota installed a bleed screw on this engine specifically to help with this. Located towards the front of the engine is a small 10mm brass fitting:
2GR coolant air bleed port
If you open this valve while filling the coolant through the radiator, bleeding the air out of the coolant will be much easier. As Eden Prairie and Chanhassen’s independent Toyota and Lexus repair shop, we hope this helps a DIY or auto mechanic out!
