Overheating Early Warning System

[MasterC17]

Shooting for end of May for 1st 10 units. Master I can bring it to our next auto-X, maybe we can even install it on the spot. Takes all of 20 minutes.

Nevermind - my graduation is the date of the next autocross so I can not attend

Adding a coolant temp switch & horn/buzzer to block drain plug as an early overheat warning ?

Sorry to revive an old thread, But can I please ask you folks about this? I have teenage drivers who are not going to watch the temp gauge like I do. They don't understand how a BMW engine can be junk after 60 seconds in the red

I know how to change the temp gauge buffering using PAsoft. But I want to add an audible alarm to both my ZHP and my E39

My plan is to wire up a simple 12V horn/ buzzer in glove box or engine bay (louder) and have it triggered by this temp switch which is threaded into the block drain plug:

This switch is threaded M14 x1.5 (matching my e39's block drain plug) and triggers at 110c which is generally (almost always from what I can tell) above the BMW 6 cyl operating temps. I understand the Block Drain may not be an ideal place to measure coolant temp as it's on the cool side of the block, but I think that is okay. I am a little concerned that this switch is a bit longer than the drain plug.

Thoughts?

Sounds like you need an UltraGauge. You can can set alarms for just about everything. I have a temp alarm set at 210 degrees so when my wife drives my car she will know when it's getting hot. The UG can check and clear engine trouble codes as well. The screen is blue but using some film (R25) it will match the BMW dash lights.

Since you asked for thoughts:

I may be old fashioned with this thinking, but I'm of the "train 'em" mentality. They need to know the importance of paying attention to the car's gauges. If the car overheats and gets damaged due to their negligence, "you break it you buy it". That'll make sure they pay attention...

Since you already have the coolant temp gauge coded to something a lot more conservative, that glowing red light in the hot zone needs to be more than enough to grab their attention (while still being in the safe zone). I would image the car beeping when it gets there, but I've never ran it that far so I wouldn't know for sure.

But that's just me. That is what gauges are for.
