    at what temperature did the water idiot light activate, and what are the chances of it still working after nearly 30 years???????

    Usually the idiot light comes on 1 nanosecond after engine damage has occurred. Chances are it still works the same or worse...

    Gauges aren't that hard to install, and then you'll be able to actively monitor temps, OP, and charging...and know there is a problem well before engine damage happens.

    In June I drove from Montana to Illinois in my '72 (1400 Mi) with nothing but idiot lights. I've felt your fear.... east of Wall, SD, @ 7am I saw two cars in an hour. it would've been alot of walking.
    Good luck.

    I find lights to be better than gauges for alerting me to a problem. Then guages for figuring out wtf?
    I buy VDO's temp senders for what ever it is that I want a light on, and wire up an indicator light. Look them up on VDO's page, then get them from Summit.
    In other words, I've not a lot of faith in the stock bits still working at their age. One race truck I worked on was wired so that the lights came on and stayed on with the ignition. When there was a problem the light went out. That way you know that the bulb is still good.

    the light system will work still as long as wiring and light bulb and sender unit are all good

    when thelight comes on all depends on the sender unit
