?!? How can you check the vehicle coolant? The only fluid I'm aware that we can access is the wiper washer fluid.
Technically, the wiper fluid is the only user-accessible fluid in the car, but you can pop off the the cover panel (the one nearest the firewall/windshield) without too much difficulty and then visually inspect the coolant tank. I would assume this is how Duck checked his.
