WHAT THE HECK IS THE MATTER WITH YOU!!!! I'm only kidding. I'm pretty sure the spring side goes toward the radiator. If you look harder at the picture you posted it kind of looks like the spring side is faced away from the engine. Later...
hahah ok thanks. But tell me why should the spring side of the thermostat should be inside the motor when that picture illustrate hot water are coming out from the engine to the top radiator hose? shouldn't it be the thermostat (spring side) towards the radiator based on that flow chart so that the thermostat could open up?
this is a quote from another link
so by that statement, I'm thinking that the thermostat spring should be towards the radiator, correct me please. cause wanna run my van with a thermostat!!!
the coolant is drawn from the bottom of the radiator by the water pump which delivers the coolant to the cylinder block.The coolant travel through the cored passages to cool the entire length of each cylinder wall. Upon reaching the rear of the cylinder block, the coolant is directed upward into the cylinder heads, where it cools the combustion chambers, valves and valve seatson its return to the front of the engine.The coolant from each cylinder head flows through the water passages in the intake manifold past the water thermostat, if it is open, into the top of the radiator. If the thermostatis closed, a small portion of coolant is returned to the water pump for recirculation.

I bought a few old (still made in the USA) Robertshaw thermostats for the van a while back. Installation instructions read "Install thermostat into groove with cone pointed toward radiator". The cone and the spring are on opposite sides of the thermostat, putting the spring towards the engine. The key is that there's an enclose chamber containing a wax pellet that drives a piston to open the thermostat. The chamber has to be submerged in coolant at all time, hence towards the engine. Hope this helps.

Not a good idea. How long does it take to warm up? For the sake of the engine you need it to warm up fast.
i have removed mine compltely. still runs fine

Took off the bad housing and there wasn't even a thermostat in there! I put a new 195 degree one in with the
spring/longer end towards the engine and the "bridge" or short side towards the housing. From what I've read and
that little video its in there correctly.
I left off the PVS switch since I'm in the process of stripping off all the emissions junk.
So my question is, do I run the 195 or drop to a lower temp thermostat or does it matter?
I'm rocking a 74' E100 with a 302 Automatic transmission.

Your engine needs more heat in it than that to run right. I wouldn’t go less than 185 & I think that is what they came with & what ‘the books' call for. 195 won’t hurt either if it’s a little cooler where you live.
I've always used lower number thermostat such as 160...
