Difference between S4 Auto and Manual trans Thermostat Housing
I need to replace the thermostat housing on my 88 FC, but it was originally an auto that has been swapped to manual trans at some point. I don't know if the engine and trans were swapped or just the trans, and apparently the thermostat housing is different between the two engines. I can't spot an noticeable differences between the two housings from pictures though, how would I determine which one I have? Or are they both the same?

there is no difference as it is the same part...on the same engine.
The only thing that makes the cars (Manual and automatic) differ are the transmissions..not the engine parts.
well..not exactly true..some shifter stuff ,pedals or no pedals..and a vacuum thingie near the Air flow meter.(if you really wanna get technical!..haha!)

There are Differences in the Engine parts IF the engine is an S4 Or an S5 though.
The difference in your case and your part would be the Thermostat neck and waterpump/housing.
The Neck on an S4 has 2 bolts to hold it to the waterpump housing.,usually made of aluminum.
The Neck on an S5 is a 3 bolt affair and is made of plastic.
Again if you wanna get further into this,the pumps differ by bolt placement(8 bolts vs 9 bolts) onto the housing but the Housing bolts onto the engine with no difference.
The fan is 8 blade on a S4 and 10 on a S5.The bore is different to place and mount onto the pump shaft so you by rights can't use the one to replace another series..BUT it is doable..(so that is why I stated that.)

I actually notice the threaded hole on the auto one now that you mention it, but that one is actually the cheaper of the two so that's what I'll go with
