Aftermarket coolant gauge in drain plug on block
ive read on this thread:
https://www.rx7club.com/showthread.p...+coolant+gauge
that the drain plug us another alternative place to use instead of stock location. the reason i ask is because i wanna use the stock OE location for my haltech sending unit and use the the drain plug on block for the aftermarket gauge.
btw does anyone know the threadpitch and size for it?

He just said he was going to use that for something else.
If you can find a sender with the right pitch, then I don't see why it wouldn't work, assuming it gets good coolant flow.
Here is how I did it: https://www.rx7club.com/showthread.p...ghlight=sender

The Haltech sensor should be placed in the water pump housing. Drill and tap for 3/8" NPT. Either replace the stock ECT by reaming out the hole and retapping, or tap somewhere else in the housing. You should not need to move any sensors.

The water drain near the engine mount is not the place to go. Been there before myself. That is a dead end passage. NO water is Flowing in that passage. It will always read cooer than the water at the water pump housing. I actually put a sensor there once. OPPPs.

I put mine beside the Coolant Temperature Sensor (AKA Water Thermo Sensor) on the backside of the water pump housing. There was a blank spot that looked like it had been designed for such purpose.
This is the same spot Aaron Cake is talking about.
Pictures!
This pic is blurry, but you can see that the sending unit is in the flow of coolant:

The gauge on the dash is a 3 position gauge: cold, warm, and rebuild. No one should trust it.
The water pump housing is THE BEST place to put the sender, bar none. It's not hard to do, so why settle for something inferior that could cost you an engine. ALL of the coolant flows past that area at its hottest, so you're guaranteed flow and accurate readings (well as accurate as the gauge can read). There's a reason why the more important ECU sensor is there, that's because it's the best spot, so they put the critical sensor there, and put the meaningless gauge somewhere else.

Here's my temp gauge sender install. I initially used the blank boss on the back of the water pump but I had probelms with the temp sender clashing with the thermostat, so I put it in the front instead.

another question kinda relating to this:
im getting the 5one5 idoit cluster pod, now since im removing idoit cluster is there a way that i can retaint the low coolant/oil light?
im getting aftermarket oil pressure, temp and coolant temp gauges but i dont think that will help to let me know if im low on liquids (from a leak or such)

I don't think any coolant flow around the area you circled in yellow...
That looks like the oil cooler line fitting.

Bad idea. That location is a dead leg that does not put the sensor in the coolant flow. You will eventually get the right reading, but it'll be delayed as the stagnant coolant slowly heats up. You have no idea if you really got the same readings, because they were taken at different times.
That won't help you if you loose oil or coolant in between fills due to component failure. That's what the warning system's there for.
It does.

But a buzzer with no light doesn't help that much, because what is the problem? People have had oil cooler lines blow out, that'll drain the pan pretty darned fast, and if you don't catch it right away that could be the end of that engine. I've had a heater hose blow and the buzzer and light enabled me to know the problem and pull over and stop ASAP and no damage was done.
