Yes: the higher rated thermostats will often allow for better cooling, due to the thermodynamic qualities of the cooling system. The stamped temp on the t-stat is when the unit is fully open. Often, the t-stat functions in a partially-open state, regulating coolant flow for proper cooling. I use a stock spec. 195 deg t-stat in my 304 (with stock 2-row radiator), and never have overheating issues.

We don't allow posting information or links to competing businesses.

We do ask that you post any questions you need help with and the crew or member will take care of you and point you to the appropriate solution.
As I have trouble getting the thermostat gaskets to work right and got NO useful data here; it is too bad you refuse us the right to seek info elsewhere. I cannot find pictures of the right orientation of gasket to housings. Even my Shop Manuual does not show it.
Two of us flipped it in all the ways we could think of and the holes do not all line up.

Post a picture of the parts you have so we can figure out why you are having difficulty with this. It's hard to envision what you are talking about without directly seeing what you have in front of you. Either you have some off the wall parts, the gasket you got was wrong or ?? In the words of Jerry Maguire "Help me help you".

I got those gaskets and a fuel pump from your site last week.
My friend works MOPAR a lot. Maybe I am really confused after owning IH trucks since 1979.

Default Re: Thermostat confusion

I think you may be confused by the four (4) bolt holes in the thermostat housing?

The housing has four holes as the housing is utilized on the IH SV-8 engine and the IH I-4 engines. In either installation, only two of the four holes are utilized. The two at approximately 9 o'clock & 3 o'clock positions. The unused bolt holes for the IH SV-8 engine are at the 1 o'clock & 7 o'clock positions. With the water bypass outlet facing forward to the water pump. you will see that there is only one way to install everything.

So, Step 1. Place one new gasket on the intake manifold so that the two holes in the gasket align with the two holes in the intake manifold with the large water hole centered over the large hole.

Step 2. Place the thermostat housing onto the first gasket so that the water bypass points to the water pump and the two bolt holes align with the two holes in the gasket.

Step 3. Place the thermostat in the housing with the "pill" down towards the intake manifold.

Step 4. Place the second gasket on top of the thermostat housing to align with the t-stat and two bolt holes.

Step 5. Place you water neck on top of the second gasket to align with the two bolt holes. Inset the two bolts and tighten to specification.

Be sure to use the proper gasket sealer on each gasket.

Here is a pic of the thermostat housing installed. Note that one of the unused bolt holes has been ground off and there are now only three bolt holes, yet only two bolts holes are utilized.

Thumbs up Re: Thermostat confusion

Many thanks for this; I change them so infrequently that I forgot the where and how of it.
My Shop Manual for this is a bit vague on details.
PS: anyone needing data or pictures from that Travelall (Lightline) Shop manual is welcome to copies from it.
