I have a 13 spyderRTL and I know fellow owners have said stuff under their breath. How the heck can I see what the fluid level is when it difficult to see it. Sure, guys flash their lites on the bottom of the translucent container to see it. Sure, guys shake the front end to see it slopping around. Here's a possible solution. Can a person put dark food dye into the container to darken the anti freeeze? I have not done it yet, but toying with the idea. I don't think it would do any harm since it is only a coloring. Any ideas out there? Has anyone already has done it? Thanks for any input.
