keep an eye on the coolant levels as that runs through it too.. best is to replace it soon of course...

Disconnect the 2 pipes going into the cabin from the engine bay and join them together to stop you losing coolant.

I found an easy way to change the matrix was to cut the pipes down and use hose instead to join to the engine bay, that way you can get it in without removing the dash.
