So I got a new aftermarket water temp gauge and I'm not sure where I screw in my little sensor plug thing to my engine, its a stock S5 13b. I. Didn't have to much time to poke around, but I didn't see anything to obvious. Info and any other usefull tips welcome. Thank you.

 

you could tap(split the hose ) into the upper rad hose with a bung welded on to insert the gauge a short piece of pipe and splice in with two claps, or purchase a after market thermostat alum cover pipe(89-90) and install it there

 

tap the thermostat housing.

 

You could put it where the stock sensor goes...near the oil pressure sending unit.

 

^that is where i have mine and no complaints. its an electrical autometer ultra lite

 

lol, you may want to pay someone to do this... but yes, the stock location ftw

 

back of the waterpump housing below the thermostat.

 

will it thread in?

 

thanks for all the of fast replies and good info. i couldnt tell if it would fit in the spot where the stock one is or not. id rather get some good advise instead of threading it in somewhere it wont fit or work. i just want the easiest way to do this that will last. sounds like the stock spot is the way to go, anything i need to do or be aware of? this is my first time every messing with gauges

 

what brand of gauge is it?
I always thought the FC had a funky metric thread that most aftermarket gauges would not thread into

 

its the IEquus 8200 2" performance triple gauge kit, it comes with the water temp. oil pressure, and volts gauges. im installing them above my AC controls in that big vent space. like i said i have never messed with gauges or anything before besides a tach. so im not sure if i got to go buy a certain adapter or if the ones that came with the kit will work. ill let you guys know how this product works out if i ever figure out where i should hook up the sensor lol

 

The FC is a weird British thread that turns out to be 1/8-28, most aftermarket sensors are 1/8-27.
I just threaded the new sensor in and it's been fine for over 4 years.
YMMV.

 

autometer makes an adapter too

 

havnt had time to install the sensor yet but i will today and probly end up needing more help or somthing so stay tuned for more stupid questions! haha
