Thermostat housing?

I Read somewhere on here that a 4.0 ltr thermostat housing will bolt up to a 258 block with no extra mods! Is this true??? Reason is I think the 4 ltr one has a port for a temp gauge, and that's what I need since I can't find a place to put my aftermarket mech temp gauge fitting.. I have a header so there is no place to put my fitting!

Any idea if it would fit a V-8.

Awesome! Did you do it for the same reason??? How did it turn out? And, would the thermostats be the same since the housing is interchangeable???

Yes, thermostat - gasket - housing are all the same between the 258 and 4.0. This is the housing with the threaded bung I use for a temp probe to control my Contour fans.

I am changing out mine for the cooling temp sensor for MPI. T stat should work but I changed mine to a 195 for the mpi.

I pulled a 4.0 housing off of a jeep Cherokee today at the salvage yard to have the tapped hole for a temp sensor. I installed in on my 1980 258, but I have some concerns about it. The outlet neck angles back toward the engine and is so close to the valve cover, I barely have the hose clamp on the neck. The 258 housing does not angle back. The flow is also very restricted compared to the 258 housing. I'm wondering if I got the wrong housing.

Pics? Is your housing leaking? I've got a 4.0 water neck and its tight along the valve cover, but still works fine. Unless it leaks or your temp goes wild, I wouldn't worry about it.

Had the same problem. Works! As stated clearance a little tight, but can be done.

For a V8 look for a late 60' early 70's J20. Summit Racing will have a picture you can look at.

I tired to use the spring clamps that were on the Cherokee, but there is not enough room. The clamp for the radiator hose hits the valve cover. I need to switch back to the band screw/clamp.
