electrical and ignition Aftermarket Gauges in a tii - Where are you running the coolant temp sender?

[danco_]

Hey guys,

 

I have a tii that came with VDO water temp and oil pressure gauges mounted in the center console. The only issue is that the water temp sender for this extra gauge is mounted where the water temp sender for the cluster would go. Which means My temp gauge in the cluster is always dead with no signal, but the VDO gauge works perfectly. I would like to remedy this by having them both work, but I don't see a solution that isn't invasive. I don't want to run the VDO gauge sender from a coolant hose adapter.

 

Is there a better location to mount the VDO sender that still looks stock, or at least leaves the engine bay clean looking?

 

 

 

Thanks,

Ryan

What about running a Radiator Drain-plug Adapter?

Or even the M10 bolt plug above the starter for a hidden application.

 

I'm sure Earle's has something like this @ $12.99:

Putting the temp sensor in the radiator will not give you the ENGINE Water temperature It will just give you the radiator water temp.  When the thermostat is closed there is no water flow through the radiator.  The only logical place to put it is in the water outlet at the front of the head (see mbaum's picture above)  with the Tii you have the gauge sender and the thermo-time switch for the cold start injector that fills up all of the ports.  You could remove the outlet and drill & Tap up from the bottom for a 1/8"NPT sender (available from VDO) it would be hidden.

My car lacks the thermo-time circuit so it was easy for me

Tii or e21/e30 M10 water neck with 3 ports.  Im using one port for the electric fan switch, one for the stock water temp sensor and one for the VDO water temp sensor.

Thats the blog post on wiring it up...

I have not seen that outlet before, I would be interested in where it was used?  The problem danco has is he needs the water outlet port for the warm up regulator on the injection pump.  If it was not injected I would say use a Tii outlet and put the aux gauge sender in the water outlet port.

Oops! That Page Can’t Be Found.

It looks like nothing was found at this location. Maybe try one of the links below or a search?

The tii water neck is specific because it also uses a nipple that routes to the kfish pump system. The water neck suggested by John won't work in my application.

 

I think Garry is onto something with the plug-by-the-alternator. 

 

 

 

But still, has this not been encountered by other tii guys?

Ireland Engineering uses these for their "dual sidedraft" set ups, along with the e21 long, metal water bypass tube that mounts to the block. It connects the water pump to the heater core inlet hose.

Ryan, u have a pic of the Tii water neck? Are u able to tap it for another sensor?

[SydneyTii]

Anyone ever solve this?

of is tapping the water divider the only option if you don’t want to cut the top hose for an adapter?

[SydneyTii]

Bump..

I just use the gauge in the cluster.  Extra gauges are voltage, oil temp, oil pressure, AFR.  Why the desire for redundant gauges?
