2012 4 cyl thermostat housing mount on engine bolt ear broke off

Hi guys,
The mount on the engine that my 2012 tacoma 4 cyl thermostat housing bolts onto has a fully broken off bolt stud ear. Can the broken piece it be J B Welded? What is the fix otherwise? What is it actually bolted onto?Looks like a very major repair job to me.
Thanks in advanced

Welcome!

 

Here is a pic for what it is worth. Broken off section is about at 8 o'clock.

If you are planning on keeping the truck I would replace the housing you broke .

 

Do you know what that housing is? Just mounted to engine or much more embedded? I would imagine a very costly repair either way? Certainly above my pay grade.

 

Its called the thermostat housing and it's a bolt on part . If you try it yourself better find a video or a Chiltons . It's at a hard to see location .

 

Thank you Bleep

Hi Boogie,
Thanks for your post. I wish it were just that. Unfortunately, the broken part is what that thermostat housing connects onto which is on the engine itself. That is what I am trying to determine. Did a J B Weld fix last night, we'll see if it works.
Thanks, Chris

 

FYI. Part that broke was part of the timing chain cover. Will have my mechanic replace it. Truck has 252K and still running beautiful other than starting to use oil.
