No more coolant baths!

I forget who posted about doing this to the W/P housing way back when, but I decided to one up it and do the T-stat housing too..   FINALLY I can drain the thing and quite possibly maybe hit a drain pan... Never have I been so excited at the thought of changing my thermostat...

THANK YOU for posting this just in time before I re-installed my WP. This is now on the mod list!

Brass and Aluminum. I wouldn't worry, but maybe some teflon tape would do good on it.

Great mod, I will do on the next WP. Thanks

The sensors have brass housings in aluminum from the factory so I wouldn't worry too much, then again maybe that's why most of the old thermostat housings are s corroded?

I used teflon tape on em..  If for no other reason a tad extra leak prevention...  I have no worries about the brass plugs..  I don't think I would use steel though... Aside from the corosion issues, I have visions of cranking the sucker in there too tight and breaking something..

 I did put a blob of weld on the t-stat housing just for a little extra meat to cut threads into..  I don;t think it was really necessary, but once again, extra insurance.....    I did consider using radiator petcocks in the holes, but I had fears of the darned things rattling open..


I believe credit goes to Fatmobile for the drain in the W/P housing....

Lucas, do you see the antiseize oozing from the t-stat bolts??

I plan on adding a block drain in my vanagon.  The engine is tipped over so much that there is a significant amount of coolant left in the block even after draining.

I guess the freeze plugs are high enough that some sort of drain in one of those wouldn't do it..  Will you be drilling and tapping the block?

one on the soft plug side of the block? that makes really good sense..
