Can you help me figure out where to add water to my radiator?
I have a 01 gmc Sierra that the low coolant light keeps coming on. I can't find a radiator cap anywhere. The only thing I can find is the overflow resovoir. Thanks

Well dude, some cars don't have a radiator cap. This is to prevent some dumbass taking it off hot, burning themself and suing the car maker.
In this case, you fill up the radiator by putting coolant in the reservoir.

Add it to the coolant (overflow) reservoir.
It will be drawn into the radiator as needed and you should check to make sure the coolant reservoir remains filled to the "Full when Hot or Full When Cold" indicator line.
The quantity of coolant in the radiator varies due to the fact that coolant expands when hot and will be forced out of the radiator into the coolant reservoir at that time.
When the radiator cools, it will be drawn back into the radiator. That's why the coolant reservoir is there.
