Water temp gauge hook-up

I did the search. On a '01 GT is there a way other than tapping into the thermo housing to hook up the elec. sensor? I understand that the one sensor thats there sends the signal to the computer and it gets split to the stock gauge. Need help with this.

Thanks,

Bill

Certainly. It's a little tough to find, but it works well. Below the exhaust manifold on the driver's side of the block near the back, there is a screw plug. You can take that out and put the sensor in there. That's where mine is. I just used my thumb to plug it while I was getting the sensor up there. You'll get a little bit of coolant on you, but it works nicely. Then you don't have to cut wires or screw up the signal to the comp.

do you have the metal crossover on your intake or the all plastic? If you have the metal you can drill and tap the flat spot on the crosover where us npi guys tap for our second sensor.

DropTopPony, I believe the crossover pipe is on the DOHV. The SOHV
is different.

Thanks,

Bill

No the 2V also has a coolant croosover on the intake...its where the temp sensors are tapped into. The newer intakes have this made of metal to prohibit the intake from cracking. Is your intake all plastic?

Heres the pic of an intake with the metal coolant crossover in the front...(not the tube on the ground in front)

Wouldn't be easier to just tap into the oem sensor signal to the PCM?

The gauge is calibrated to its own sending unit. You may get an inaccurate reading. I personally don't like the idea of drilling and tapping into a coolant passage. How do you keep the shavings out?

the coolant passage unbolts from the intake....easy cleaning after drilling and tapping.

Well that's cool. I had no idea that it was removable.

Thanks, I put the sending unit in the tapped hole in the block on the
driver side under the exhaust manifold. Very easy and I keep my stock gauge
working. I also installed the oil pressure sender in the vacant spot under the stock unit. All and all, painless.

Thanks to everyone.

I meant to tap into the wire which sends the signal to the pcm.

I know where you're coming from. I just suspect that not all aftermarket gauges are calibrated the same nor are they calibrated to the signal that the ford PCM uses. I could be completely wrong though.
