Taking a look on here but cant seem to find the heater valve, I can only see expensive items which I hope aint one of them...

Mine was the top O-Ring, Matrix is £57 from GSF Brand is NISSIAN dont get any other like cheap £20 ones from euros, BEHR are OEM but way over priced. If it is the heater valve get a second hand one they are about £160 from BMW

Also check that your coolant bottle pressure cap has been changed under the 1997 recall. Still plenty that haven't and still causing leaks.

Mr. moore's best and most common sense advice was use talc powder and use it too see where the leak is coming from, if it wasnt in your face... TOP TIP!!!

i have a good heater valve here and a good matrix if needed

can i get away with removing the valve and replacing the o ring? or are there any other issues which causes said part to fail
