What temperatures do the idiot lights actually engage at? I’ve always assumed if it got to the point where the hot light came on - you’re screwed anyway.
Just be aware of one thing: right now, with just idiot lights, you will drive your car and enjoy it, without any thought to the heat in the motor as long as the red one is not lit. But, once you install the gauge, you will always be aware of the temp and wondering if you're too hot. It's a great way to destroy a nice drive.
Just my opinion....
There it is! My "Hot" light did come on in my Newport.Here's an idea . . .
By observations going back into the middle '60s on our '66 Newport and other similar factory a/c Chryslers (and from techs who worked on them), if the factory cooling system is clean and has a good radiator cap, you'll never see the "HOT" light illuminate unless . . . there is a leak and part of the coolant has leaked out, a failing water pump, a failed thermostat, or a failed fan clutch. Now that the cars are now much older, these "HOT" modes might also include a cooing system with a lot of "accumulation" in the water jackets that needs new freeze plugs and a good flush when they are removed for replacement.
