I dont understand why you wasted your time posting this, somethings are not meant to be understood.

Go to Autozone... But a Sunpro "sunparts" metric adapter kit....

It screwe right into the allenhead bolt on the side of the filler neck, and the autometer sender plugs right in...

ZeroBanger

doesn't the sender have to touch the water to work?

DamonB

It's just an adaptor. It merely allows the aftermarket sender to fit in a stock hole that's already there. The sender still extends into the coolant flow.

ZeroBanger

Ok, but u need a special tool to remove the TAP that is currently installed, right? I think thats why I was confused by his statement.

DamonB

Everyone I have seen is just an allen head?

rjuge

just an allen head...

ZeroBanger

oh wow thats cool. I'm gonna try this maybe tonite.

ZeroBanger

I should ask another New-B question before I try this..

I can do this with the housing on the car if I choose the one on the top of the housing, right?

Mine came with a 1/8 sending unit and a 3/8 and 1/2 NPT adapter. Does anyone know the size of the NPT adapter I would have to put in the housing? I think it looks 3/8, but I wanna make sure.

thanks alot.

Yep, you don't need to remove the housing for the install. Just remove the hex bolt and put the fitting in it's place. You might have to cut on your coolant cap to get it to screw down again.

ZeroBanger

cool, do you know if its 3/8 NPT fitting?

Mahjik

I don't remember which fitting off hand, but once you remove the hex bolt, it will be obvious. Only one will work and they aren't that close in size.

ZeroBanger

Oh I understand it will be obvious, I just wanted to make sure i have the right one that fits when I attempt this. Otherwise I have to put it back on and buy a new one and hope it works.

thanks so much for your help, its appreciated.

rjuge

it's not a 3/8, it's a metric size (unless you want to try the :teflon tape idea"..... that adapter kit was less than $10 i think.... definitely the way to go...

ZeroBanger

I decided to get a T adapter and do the throttle body thingy. DamonB is never wrong.

Thanks!

damonB is a genious!!!

My power FC and my aftermarket water temp gauge read exact now!!

ZB, What adapter did you use?

ZeroBanger

I went to orchard supply hardware and got some ugly 1/4 npt Tee and with 2 NPT 1/4 barb connectors. Oh yea and a 1/8 to 1/4 NPT adapter.

costed $4.97 all together and took 20 minutes to insall.

I looked for some hardware to install a VDO sender in the TB line, but I couldnt find anything with the right thread pattern. I went to Home Depot. The thread pattern for the VDO sender is the same as the oil drain plug. Home Depot didn't carry any "automotive" thread pattern hardware.

DamonB

My VDO fit into the brass tee just fine with one of the adaptors that came with my sender.

Didnt feel like reading all these posts, so not sure if this has been suggested. Anyhow I have a autometer electrical water temp gauge, and I screwed in the sensor right into a hole in the thermostat housing, after removing the unused bolt with a hex key. The gauge comes with an adaptor with pipe threads exactly matching this hole. Hope that helps.

I tried this and it's almost true. If you want to force it in there you can and it may work without leaking. But autometer pitch size is american and the stock one is metric.

Let's dig this thread out again.

I have a few Q's to add.

Which throttle body hose (there are 2 right?) are you guys tapping into? Is it the one that is clearly visible with the 90degree fitting next to the firewall (I hope)?

What size hose is that? I have a Defi sensor that's 1/8PT with a 1/8NPT adaptor (yes, they're both 1/8, I suppose one is metric, the other isn't). Anyone got an easy fit solution?

Thanks.

I did mine a few days after I originally posted in this thread. I used the coolant throttle body hose near the firewall, just behind the manifold. It took 15 minutes to do. I dont have any pics or part #'s but I can tell how I did this. I went to orchard suppliy hardware and bought a brass T connector. The T connector I bought was a 1/8 to fit my 1/8 sending unit. It also required two 1/8 NPT to barb connectors.

basically, on my lunch break I took my T connector and then screwed on each side one of the 1/8 to barb NPT connectors. I used teflon take inbetween to keep it sealed. I removed the end of the throttle body hose that connects to the manifold and slid it over the barb connector and used a metal clamp and tightened it. Then I had a 6 inch 3/8 water hose that I connected to the other NPT barb connector and clamped it down. And lastly connected the other end of the hose to the manifold. Oh yea, then I screwed the sending unit in and sealed the outside with a little JB weld, since the manufacturer does not recommend using teflon tape on the sender.

without pics, Im sure this description doesn't do you any good but trust me when I say its a 15 minute job and is very accurate to what the POWER FC Water temp is (within 2-3 degrees F). The only difference is the water in the throttle body hose does not heat soak after you turn the car off like the stock sensor does.

InsaneGideon

Wow. What a quick and complete response! No need for pics.

Thanks Zero. You 'da man!
