Searched hi and low for a tutorial on how to replace a heater core in my mazda 5 . Does anyone have a step by step guide on how to do this ? Do I have to tear the whole dash out to get at it or is there some easier method . Any help or pics would be greatly appreciated .

 

Dashboard removal is required.

The Mazda 5 shares alot with the Mazda 3, I only have experience with the 3 as the 5 wasn't sold in my market.
