If your reservoir tank has cracked due to age or the coolant level sensor has stopped working, replace it with this OEM GM part. These tanks often get stained and warped over time making it difficult to monitor the coolant level or even have troubles threading the cap on and off. This tank assembly includes the integrated low coolant level sensor.
