Stock E90 328i Thermostat disassembly.

After a P0128 engine code, I tear apart the original thermostat at 130k miles.
Three bolts hold it together, T30 socket will be required. It's actually a little stuck but since it's junk, tear it apart!

When you going to clean up and disassemble the water pump?
