I am replacing the t-stat in my 06 ford f350 and am curious if there is a certain direction that it needs to be installed?

 

Don't they usually come installed in the housing?

 

You can't put it in wrong. It comes already in the housing and only fits one way.

 

That's a pretty bold statement Tim. I think I've seen one or two on here that could manage it. LOL

 

Thanks, I have the housing and the t-stat as one piece but I just noticed that there is a little dot that sticks out a little and just wanted to make sure it doesn't
have to go a certain direction. It will go in both ways so I was just curious.

 

Make sure it matches the one you are taking off and you should be fine.

By the way, welcome to the forum! Take a look in the Tech Folder there is a huge amount of useful information hidden in there.

 

It matches, I just didn't take notice which direction the old one came out.

 

IIRC the housing outlet points straight up so rotation should not matter. Is that what you were asking about?

 

There is a small bleeder hole to get all the air out of the system. Make sure that is on top or up.

 

It cannot go the wrong way, because the bolt holes are not on the centerline.

 

Bill, correct me if I'm wrong, I'm going by memory. If you remove the t-stat, from the housing, for a flush it can be loaded into the housing wrong and the bleeder can in fact be 180 degrees out.

 

You mean, like inverted upside down? I don't think it can.

If you mean rotate it 180°, yes I think it can, and I don't think it would matter if you did. The vent would still work.

Here is the thread where I originally posted those pics. There are some more pics that might help.

This is what I meant and yes the vent would be 180 degrees from the way it was taken out originally. I can't say it would or wouldn't make a diff. I would rather not take the chance of trapped air that I couldn't get out. It was on the top when removed and that's where I felt it should go back in.

 

I dont think it matters the vent/bleeder location just cant be clogged with junk


for the op just have to twist and push the tabs

 

I agree, better be safe than sorry. The purpose of the vent I believe is to make sure air can pass through, so that the thermostat gets wet. It would never open if in a trapped air bubble.
