The Heater Matrix has sprung a leak on my 900S and I'm keen to get it fixed since the temperature is around -4c, making the 35 mile trip to work a bit chilly. Is this a difficult job to do and how many hours should I allocate to myself in getting it out? I'm a fairly competent amateur... Don't say don't do it though.


I've just seen a previous post about leaking couplings so i'll investigate them first..

 

What year is the car? Do you know what exactly is leaking?
