Q: Car is still overheating - 2006 Acura TL

There is no bleed screw on the 2nd generation TLs. Bleed the cooling system with the nose of the car higher than the rear if possible let it heat up at an idle until the thermostat opens and allow all the air bubbles to escape with the heater going full blast. Some techs will drill an 1/8" hole in the flat disk portion of the inner thermostat core to allow air to escape better during the bleeding process. The thermostat can easily handle the small amount of coolant flow difference this hole makes. If this all seems daunting to you, I would recommend having a cooling system flush completed by a mobile, professional mechanic, such as one from YourMechanic, to resolve this repair issue.
