Maybe a month and 1/2 ago, my B2300 (23NS duratec) threw a hot light driving out of town, rolled to a stop by the side of the road and called AAA
The cooling system has no radiator cap, but a coolant bottle that I believe cycles coolant continuously thru the system (NOT an overflow tank) The coolant showed right on the low line
A visual inspection seemed to reveal the WP blew a seal on just 15 seconds before the engine was shut down and very little coolant was lost and engine didn't run with the hot light for more than 10 seconds
Got the WP and thermostat changed, and all new coolant which was way overdue (had 2 gallons @ home already to do myself)
Drive around a week or so and it the coolant appeared to be 2 qts low; topped that off and assumed it was air in the system. Several inspections after and the coolant level was stable.
Today was driving early in the morning and turned the heat on and there was no heat; i figured a vacuum line was loose so i checked under the hood and the coolant bottle was basically empty. Filled with almost a gallon and the heat started working (no "hot light" appeared) Drove around some more and filled almost another gallon.
Is it possible the heating core and system was completely empty and required almost 2 gallons of coolant to refill? and why didn't the hot light go on when the system was so low (obvious answer it was not overheating) Any comments for my understanding this better is appreciated.
