Anyone ever changed out the heater core in a 1st gen Sequoia? Think I need to replace mine. Getting a coolant smell at times, not sure its the heater core but have had moisture on passenger front floor. Just really curious how involved changing out this heater core is? I cant find any videos on the internet. I maintain my own vehicles when possible but am usually able to find plenty of information on the internet before I get started. Its an 07 Sequoia with about 140000 miles on it.

Thanks
