Hi..there..
Depends on the car or vehicle..some can be removed without removing too much trim removal to get at the heater box..in which once the feed/return pipes are removed it can be slipped out and another installed.some vauxhalls are like that..some require the complete dash to be removed to get the heater box out to remove the Matrix itself...so it can be costly..one thing that would need to be done is to determine that the leak or fluid thats gathered in the footwells is actually engine coolant..as thats what passes through the matrix itself..so if you are loosing coolant and finding the footwells wet or soaking and smell of coolant then your matrix is at fault..If its actually rain water or clean water..then steps need to be taken to check scuttle chamber drains are clear..
