I really didn't know where to put this. So if it's in the wrong section, please move accordingly.
I read a post that had the Mitsubishi part number for the BISS screw. Now I can't find it. I searched and searched but couldn't find it. So if you know the Mitsu part number for the BISS screw, please pass it on. Thanks!
if your biss is leaking, replace the seal, not the screw itself.....if you want a replacement screw, im sure many members on this board have extra ones (including myself)
No harm in buying a new screw, seal, and rubber cap to freshen the car up. Brookdale Mitsu should have all that plus a new thermostat in stock for you.
