Taken today at a funeral for a former chief who died.
Its needed only a radiator is the last couple of years
Neat
step dad refilling something 
I have no idea
thats real sweet!!!
he is putting water in the radiator. The rad cap is right up top in the open on those things. They do not use traditional coolant just strait water so he is probably toping it off.
How do I know? because that is a pressurised water can he is holding with the top off. If you look closly you can see the water going in at the base of the red ring… 
nice!
