Looks good folks. Just curious why you all didn't mod the OEM temp gage? Raventai put up a chart of temp numbers corresponding to needle position after the mod. I have done it on two 80s and wouldn't go any other way.....

I think you would go this way if you ever tried it. Nothing against the other way but the digital is very nice.
 
Digital gives your degree by degree at a glance
 
For those of you installing the water sending attachment......are you just cutting the hose in half and installing, or are you cutting a section of the hose out ? Wasn't sure if just cutting in half and installing would bind the hoses up and cut down on water flow. Thanks

I roughly measured and cut out 2" or so.
 
anybody have the raventai factory temp guage mod and also installed the koso temp guage? if so im wondering what the actual postions of the oem guage compare to the real temp reading through the koso guage
 
The actual temp numbers are posted in the RT thread. I agree with the utility if having a digital gauge but don't like extra/redundant stuff hanging around. Plus I can't stand blue lights--I have removed a couple pretty slick mods because of the bright blue lights...
 
Did this mod today in about 1hr. Super simple install. i cut about 1.5" out of the upper rad hose, and put the adapter inline. Pulled power from the grey feed wire that used to run the power antenna buttons (as i swapped out for a standard mast). grounded at the same location. velcro'd using better stuff then they provided.. i didnt even open the bag for it, just tossed it.

1/2 banana job at best..
 
I used thread sealant..... It was the closest thing I could find in my garage. :lol: So far so good.

I used Teflon tape as that was what I had. No problemos. Works like a champ.

I presume y'alls temp sender units were 1/8"NPT?

Turns out our Koso unit included a sensor with what looks like a M10/1 thread, which would require an O-ring (5/16 id) to seal. Good thing the glo-shift piece is 1/8" NPT :rolleyes:
 
Yes. 1/8"NPT

Looks like browsing around the internet there is optional threading.


incl. standard temperature sensor with P1/8" thread - wiring kit - manual in english language

optional accessories available:

oil drain plug adaptor for that sensor
sensors with different thread
sensor for aircooles engines
CNC machined adaptor for mounting sensors in a water hose
 
I called the store in Texas that sells them on Amazon: they cannot verify that they ought to come with NPT thread - they suggested I return it
 
found in an e-bay listing for it:

Temperature sensor with M10 screw - cable length 10cm
 
yup, ordered the exact parts - through the same vendors
 
Hmm I likey. I have the Android Torque app for my 1FZ and while it's great, I think this would be a worthwhile mod. Much easier to start the car and see temps right away then have to connect the Bluetooth adapter and open the app on my phone.

Does anybody have some clear shots of where you installed the water sender attachment? The pic a few pages back isn't too clear. Does it matter where on the upper hose this is installed? I can't imagine the temps varying all that much with just a few inches of space difference.
 
Mounting the adaptor in the upper hose. While I don't have pics, I can say that if you take the hose off completely you will see that there is only a certain amount of the hose that has no curvature. I just put my adaptor against the hose where it was straight and marked the hose with a pen, cut and installed.

I didn't even go that far, took the top off, quick markings, cut and reinstalled. I did slide the clamp down, tightened a bit and used for a "straight cut/edge".
 
I walked outside and took a couple of pics.
