EFI, Electronic fan & temp gauge: Need water temp. Any nice looking solutions?

[WILDHORSES]

I'm sure this has been done just looking for ideas before I start drilling more holes into my intake manifold. I have at least three temp sensors (all different) looking for water temp. To be specific we are running Dakota Digital dash, Spal brushless fan and EFI. Wondering what you have done in similar situations.

I used the Ford waterneck with a fitting in it for temp controlled spark to give me an extra location. The trick is these do not see the engine warm up - they got from near room temperature to engine temperature when the t-stat opens. Works fine for a fan because it is going to be hot anyway. Another option (before I drilled a second hole in my intake) is to use a t-fitting in the heater hose line that comes off the waterpump.

Or this in the rad hose

You can put one in the t stat housing. Some have a plug already in them or the have a boss that can be drilled. Another option is a fitting in an inline peace in the upper radiator hose.

Like others mentioned, it sounds like if you can run the fan off one in the t-stat housing, you should be good. Two existing holes in the intake.

If you're EFI I don't know if you've already committed that thermostat housing port to your water temp sensor ...? Can't really put a T there so the next best available option might be that radiator hose like a couple have already mentioned.

Jim:

You're running Ford EFI, correct?

I let the ECM control all of that:-X

Hey Todd, this is for Sheyla's rig. We have a Holley Snyper sitting on the motor right now. We'll probably break it in with a carb just so we have less to worry about with the new motor. I'm going for "show/go" in the engine compartment. I'm trying to hide wires etc. Kind of hard with all this aftermarket cool stuff. I think I can tap into the threm housing for the fan or better yet just buy the one with the hole already in it. Still considering the third sensor position.

There should be one on each side of the intake at the front. If not the boss is there you can drill and tap it. My 95 or so Mustang did not have the second one drilled.

Do not use the bosses at the back of the intake (they can be drilled and tapped) because the sensor will read low the water has not been through the heads yet.

EFI temp stuff usually taken where the mid 90's explorer/mustang did, by the sender on the heater tube on top of the manifold next top the dizzy.

 

[toddz69]

OK - then my comments about all the fittings in the manifold don't necessarily correlate because I was referring to an EFI manifold. On mine, I have one near the front for the EFI water temp, one for the temp sensor for the cluster and I have another one in the rear that I use for an auxiliary temp gauge. Plus a plug in the t-stat housing.

I used this on the upper rad hose for my electric fans on my 91 Stang. Works great.

With Ford explorer efi, I only use one coolant temp sensor on the entire engine. Its for the ecm. Then I have an add-on module for the dakota digital gauge that pulls that data from the obd2 port to display engine temp. It also pulls speed, gear position, rpm, fuel pressure and I think can do CEL.

DD also has a fan controller module that will interface with the gauges. http://www.dakotadigital.com/index....t_id=852/category_id=438/mode=prod/prd852.htm

I welded a boss to the side of the gooseneck for my fan temp sensor...

I have the aluminum thermostat housing from Wild Horses.

You could put a brass T at that one or the one at the manifold to give you three.

 

[WILDHORSES]

Thanks for all the options. I especially like the one about using a part located in our own warehouse ;D.

Hah!...what better place to put my 10,000th post than in a silly response to one of Jim's?...and hey Jim...get those new adjustable drag links going out again, willya??
;D

I welded a plate to the hot side of the radiator and tapped it to install the temp sensor for the electric fan. I have since ditched the electric fan but the sensor is still there. Then used the one port in the manifold for the gauge and the explorer heater hose tube/neck for the efi temp sensor.
