2005 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the Coolant Temperature Sensor on 2005 Buick Park Avenue?

  A: Start by turning off engine ignition before draining the coolant down to ECT sensor position. First disconnect the ECT sensor electrical connector while you remove the ECT sensor with care. Apply thread sealer GM P/N 9985253 or equivalent to the installation point but maintain care to not damage the coolant sensor because sensor damage may affect fuel control system functionality. When installing the ECT sensor verify that you use the correct component part number according to the application need. All repair procedures contain information for component thread locking compound and lubricant and corrosion inhibitor and sealant requirements, including designations when components arrive pre-coated with these items. Unless otherwise specified the application of these coatings should be avoided as these components could alter the delivered torque and operational functionality. Begin by applying 20 N.m (15 lb ft) torque to the ECT sensor then connect the ECT harness to the sensor while also refilling the cooling system.
