Block Heater that Fits 2023 Chevy Traverse with 3.6 liter

Published 12/15/2025

Question:

1. Can you confirm that the KH 11811 will fit my 2023 Chevy Traverse? VIN: 2. One of the Notes on you page says Do not use this heater with a 100-percent antifreeze solution.inch Does this note apply since this is a cartridge style heater that fits into a cavity on the engine block and doesnt come into contact with the antifreeze? 3. Where is the cavity located on the engine block for my car? 4. Does this block heater have an internal thermostat?

Hey Terry, we can confirm that the Kat's cartridge heater part # KH11811 does fit your 2023 Chevy Traverse. Since it installs in a cartridge the antifreeze fit tip does not apply like you mentioned.

The cavity on the engine block to use is the RL position which is on the back side of the motor on the driver side closest to the driver side.

This does not have an internal thermostat either but it won't over heat anything.
