Thanks for the picture! To add a block heater on your 2020 Toyota Sienna you'll want the Kat's Heaters Custom Fit Engine Block Heater item # KH11813. It will install in the factory-intended block heater port on your engine block. It will plug into a standard grounded outlet.

Please note that the Kat's item # KH11813 will only fit the 3.5L V6 Engine.

For installation help, you'll want to go to the product page of the Kat's item # KH11813 and scroll down below the pics on the left side you'll see a box that says, Locate installers near me. Go ahead and click on it and it will take you to a page where you'll be able to enter your zip code. Once you do this you'll be connected to our network of reputable installers in your area.

Hey, how did things go with the Kat's block heater for your Sienna’s 3.5L engine? Did the install and plug-in setup work out as expected? Your update could make it easier for others getting ready for winter.
