Probably seems like an easy question but I'm installing an aftermarket water temp cause the factory one sucks. Where is everyone installing them at?
13bt water temp gauge

What temperature are you trying to monitor? The stock temp sensor only reads block coolant temperature when the thermostat is open.

Anything better for coolant. I started having coolant issues and when coolant would start puking out I would loose my temp gauge. Now I'm putting a new head gasket on and id rather have a safer way to monitor temp
coolant where?

Just the overall engine coolant temp
at what part of the engine?
consider installing the new temp sensor in the coolant loop at the lower left side back of the block where the coolant exits the block to feed the heater circuit. This loop flows coolant all the time. That's where I tee'd into the coolant circuit to feed the FPHE that heats the fuel mix I burn.
That location next to the existing temperature sensor only reads coolant temp in the radiator circuit and will only read block temperature if the tstat is fully open when the engine is close to overheating.
You can also locate the sensor in the coolant circuit tube that cools the turbo

The "what part of the engine" is my question. I don't like the factory spot. I'm looking for a reliable spot.
So you are talking about putting a sensor on the heater core lines?
Well, color me confused. I put the sensor on the lower portion of the t-stat housing. My understanding of coolant flow would suggest this IS where you would get coolant temp from engine block coolant. Coolant flows through engine block until it reaches temperature that triggers thermostat to open at which point the coolant goes UP through the t-stat, to the top of the radiator for cooling, then is pulled back into the engine by the water pump where it starts all over again. Is this not correct?
Temperature monitoring on my 13B-T showed that because the sensor in the T-stat housing is above the T-stat it didn't always give an accurate indication of the coolant temp in the block as it was effected by the changes in the amount the T-stat was open. Locating a temp sensor on the heater loop right where it comes out of the block gives much more accurate readings of block coolant temp.

Envy is green, sad is blue, and rage is red, what color is confused?
I'll go with red for confused because I blush when I'm embarrassed. I get why the heater circuit would be a good place but I'm still confused/embarrassed/red about the t-stat housing temp sensor. OEM and my aftermarket port are on the lower part of the housing which is below the t-stat, yes? Your OEM sensor is on the upper portion of the housing?
I was mistaken, you are correct.
I'm not sure why the temp at the heater take-off reads higher than the temp at the Tstat housing. On that basis I considered it a more accurate indication of block coolant temps.
