Extra bungs on new thermostat housing

[alexjcr]

I've changed a couple of old dirty parts from the cooling system on my 325i and I'm a little confused about the new thermostat. It's got 2 extra bungs right by the thermostat cover.



I'm sure there's a lot of you that have seen this before but, with my good luck, I can't seem to find anything about it. What size bolts can I put in there to cover those holes?

It's extra bungs for aux sending units such as a water temp gauge or a sending unit for an electric fan .. You can cap them off no problem I believe the threads are m12 1.5 but I could be wrong .. If you put a bolt in it make sure you have the copper seal for it

I'm looking for the thread size for the bolts I want to buy. Luckily, someone here knows it by memory. I could take the housing off and take it with me to the shop, but it's not really what I want to do.
