Thank you for taking the time to make this. I was curious how the back core was changed - thanks!

Thank you, you helped me replace my heater core.

So you knew to change the cores only due to the smell of coolant? Is the smell constant? Sometimes I smell a weird chemical smell and not sure if its coming from outside or my truck

It’s fortunate that it’s not a car to take out the whole dashboard.
