Hi All

I would like to fit an aftermarket electric guage to my 80 with a 1hz motor the problem is where to install the sender. The guage I have is an OEX brand and the sender is the wrong size to fit in where the origional sender screws out from and I can't seem to find an adaptor to make it fit.

I thought I could put a tee onto the alloy top radiator hose housing where the AC senser screws in but it has it's own special housing style so no joy there.

The only other option I can think of is drilling and tapping a thread into the alloy housing of the top hose (it has a little flat section on it) and fitting it in there.

Other than the idea above I am realy stuck for ideas and would like to have it in by next weekend ANY thoughts would be great

regards Trevor

I would seriously consider one of these.... better and does much more the a standard temp gauge.

Hi Trevor:
If you decide that the Engine Watchdog is for you, let me know. I have an almost new one here that I intend to sell shortly. I bought two, but the second car was sold a week after it was fitted, so it was taken out. Might be able to save yourself a few bucks. I paid almost $150 for mine.
Cheers

Hi Trevor,
I have a 1HZ with a watchdog fitted and it is worth it's weight in gold, i placed my sender at the front RHS on the head but i do think there is probally a better spot as it fluctuates a lot as it is near where the return water from the radiator goes but at the end of the day it still works well and has the alarm and that is what makes it so good, you cant alway be glued to the gauges so a noise is the best way ....
I note you say you looked at placeing it where the old sender was, i would NOT remove the original system as it still gives you a back-up reading and something to compair to your watchdog as locations on the motor varey greatly as to what sort of readings you will get, even if it is not working at the moment, get it fixed first and add the "watchdog" as a secondary unit ...

I have 2 senders on mine through a spring return toggle switch that has the engine temp as the primary one that if always returns to and the second unit is attached to the transfer case, i had trouble with it and it got really hot before it blew yp so now i keep a better eye on it when working it hard off road ....
The guys at Roo Dog 4wd will sell you the kit to add a second sender if you wish .....

Cheers and good luck

The temp Watchdog TM4 (upgraded version of the TM2) now comes with two temp probes (one for engine and one for gearbox, both with alarms) and a low oil pressure warning alarm.

Trev, for what it's worty - I'm pretty sure the threads for the temp fittings (toyota) are NPT style and most stuff you buy off the shelf is most likely BSP, and in the size that the temp fittings are there is 1 thread per inch difference. My experience anyway.

I had an Engine Watchdog that I fitted to my Toyota, but the digits packed up after a couple of months.
Unfortunately I found the display to be clumsy and awkward size/shape and difficult to fit neatly and out of the way. Display is pretty much the size and shape of a 50 pack of gaspers.
Luckily they refunded and I got a Engine Guardian of Ebay ($129). Much more compact and attractive display, plus a few more features such as relay to run electric fan, easy over-ride button to go up 5 degrees etc.
