question about water temp gauge

Post by **dj_lennon_franz** » Mon Jun 07, 2004 5:24 pm

where exactly do i mount the probe??? do i need to drill a hole in the radiator or in the radiator hose??? i have one on the way (as the stock temp gauge SUCKS) and this isnt exactly something i wanna screw up yah know

Best bet (and easiest) is the Greddy and/or Nissport adapter that lets you splice it into the upper rad hose. I've got one on order, it's pretty damn trick.

Here's a pic of it. http://www.splparts.com sells the greddy one, which is cheaper than the nissport.

The sensor from your gauge screws into it, and then you splice the upper rad hose and clamp that in place.

Sure you could buy the fancy $75 billet piece and hack it into your radiator hose....OR, you could just do what I did: Drill a 11/32" hole in the upper radiator neck (the one that bolts to the side of the head by the cam sensor) Drill right throught the sticker that says "never open hot!". Then tap the hole for 1/8NPT pipe thread(if you dont have that tap, spend the $4 and go get one at a hardware store). I chose to use an autometer water temp gauge with an electric sender, which uses a 1/8NPT thread. Install the sender with some teflon pipe tape -do not overtighten it!- , wire it up and BAM! you are ready.I have had no troubles with mine, it works great. Be careful tapping the threads, this is aluminum you are working with.

Do not drill into your radiator or radiator hoses! They will leak

if you kept your KA radiator and made a crossover pipe, you could drill and tap that. That's where my current temp sensor is to switch on my fan.

c'mon now, it's only $30

What compression said works just as well too, I'm just using the greddy adapter since I got a good price on a used one.

If you need to borrow a tap and proper bit for it let me know, I've got a bunch sitting in my garage.

I have the HKS water temp adapter similar to the one msaskin posted, but out of the 4-5 metric-npt adapters that I have none will thread into the billet piece. I think I am going to drill and tap the water neck like compression stated.

Compression...do you see any need to mount sensor on it's side or do you feel the complete probe is underwater when the motor is running. I just don't want the sensor to be surounded in air and not water. BTW, I have an autometer sensor so thanks for the drill and tap sizes.

Thats the problem with the JDM sensor adaptors, they rarely use a standard NPT thread like all the Autometer sensors require. Be careful of that.

THe sensor does not need to be mounted on its side, there will be plenty of water flowing through there. The flow area of the neck is kind of small, I would make a new one if I could, so I imagine that it is running full capacity when the thermostat is open. ANyway, I get constant temperatures that are very reasonable, so I wouldnt worry about it. Besides where the sticker is, it is a little thicker, which allows more threads to engage with the sensor.

Cool, thanks for the info. I bought a tap last night and will try it out this afternoon when I get home.

Hey guys did my autometer sensor today following Compression's post and thought I would share some pics.

Sorry in the first pic I had one of the light condoms over the wire terminal.

acautotechnic makes one that fits autometer like the blue one above. it was like $40.

you the man!!!

i just did this and it works great. i've never tapped any threads before and my first time worked like a charm. I can't believe i hadn't have done this sooner.

thanks

just a quick question. what temp are your autometer water temp gauges reading?

mine is reading 155 as normal daily driving temp

i have a koyo rad, nismo thermostat and cap, and 2 10" or 12" FAL fans.

i think the temp is just way too low to be accurate. any ideas?

Im using an autometer water temp gauge with the probe mounted in the water neck as well. My water temps will consistently sit at 180 for daily driving.

I have a koyo radiator, nismo radiator cap and a permacool 14' fan. Stock t25 at stock boost.

Im pretty sure your readings are accurate and it is mainly due to the Nismo thermostat you have installed. It opens at 144 degrees and is not recommended unless you heavily track your car. The stock thermostat opens at 170.

Id say ditch the Nismo unit and put a stock sr one back in.

ok well i just wanted to know if the reading was somewhat where it is suppsoed to be. i do drift my car on a regular basis and it gets beat on pretty good and temps will climb to 180-210, but quickly go down.sine i now know it is working i think i'll keep my nismo thermostat since before i had it, it would read in the 180 range for normal driving, then when drifting get way up there in temps.
