Ordered and shipped. :tup:

any reason you guys don't feel like removing the thermostat housing, drill and tap, place sensor there?

would look so much cleaner, not create more failure points and achieve the same result?

I’d rather have a purpose made piece than drilling a cast piece. I’m also a function over appearance guy.

Plus there is no good place to drill and tap on the housing. Not enough room and it's too thin for threads.

time for new billet product... ?

I like your thinking. :rofl2: Something with a lower temp, and a place for a sensor. :tup:

The wheels must be turning. I smell smoke from Chicago. :eek:

something like the spacer they have for the sr20?

for example

The thermostat spacer is clever but it’s not standard to measure coolant temps after the rad instead of before it. The stock sensors are on the water outlet housing on the rear of the engine. The thermostat area will give you water temps after the rad already cooled, or water inlet temp.

Seems like the easiest place to put the sensor would be the water housing at the front of the engine on the timing cover. Unless you wanted to be super clean and remove the rear water housing from the heads to weld a bung on.

Pretty soon I have to make a billet front water housing anyway (one that clears our front throttle intake manifold), so I’ll keep this thread in mind when starting that project.

You got me confused. :confused: The thermostat is before the radiator, not after. So if the sensor is on the thermostat housing or the upper hose. It will take the reading before the rad. Not after like you explained.

I agree ............ thermostat spacer would do the job .......

Charles - I'm hot to trot ........ let me know when you have this done ..........

Just for the sake of eliminating any doubt....

Diagram is wrong. That is the first time I ever seen the thermostat AFTER the rad. It's always before.

Additional text from Nissan so that you don’t have to take my word for it. Notice what is referred to as the water inlet, and what is referred to as the water outlet. Also consider where the factory temp sensor is, and where it is not.
