Product Q&A

I have a 05 Cadillac Escalade and there is nothing on the bottom of the radiator reservoir to connect the sensor level to. It does have a port but nothing electrical inside. Is this normal ? HelpTy W.Nov 01, 2020
Best Answer:Hi Williams, The level sensor is installed on the port. That port is the place/hole provided for the sensor to be put into. Still, we recommend referring to a trusted vehicle specific repair manual for details about this particular part. Also, it is best to consult your trusted local auto repair shop or dealership for this as well if you need to. You can find more information here as well: <a href="https://www.carparts.com/blog/why-you-should-always-consult-a-repair-manual/" target="_blank">https://www.carparts.com/blog/why-you-should-always-consult-a-repair-manual/</a>
