I've had those sensors go bad, I unplug it, and put a stiff paper clip(obviously not a plastic one) in the plug ends. Basically bypassing the sensor. Use caution tho, if you blew a hose you would lose all coolant and the engine will not shut down. That sensor tells the ecm to shut the engine down upon dropping coolant. You should be fine, just pay extra attention to your temp gauge so you catch it if it blows a line while you got the sensor bypassed.

Typically the smell of coolant is quickly followed by thought " Ah crap."

I forgot to add 1 more thing double yellow & anyone else who this may help

you can go to autozone & buy pigtail that fits some detroit sensors. like the one that is on the thermostat housing. fits perfect. part 254 I got a couple spares when I got this info. about 150% cheaper than dealer too.
