how is this product installed?

Not sure if you meant used rather than installed. You need a set of A/C gauges. It is a bit tedious to explain. You will on see that on these gauges that you have 3 hoses, 1 goes to high pressure (red), one goes to low pressure (blue) and one goes to the Freon Canister (yellow). You need to pour appropriate amount of dye in the yellow hose before screwing it on the set of gauges (opposite to the end that would go on the Freon canister). Try to find a video on the subject. It will be easier.

After putting it in I don't see any leaks. How long does it take to be able to spot a leak?

Thank you for submitting your question, please be advised that after following the instructions you should notice the leak within a couple of minutes. For any further information please reach out to us on 800-776-1530 or autohelpline@energizer.com to assist you better. A/C Pro Consumer Services. Thank you!

What UV wave length of a light source be the best?

This is the flashlight I purchase for detection https://www.amazon.com/gp/product/B07V5QZDKW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Can i put this on my water reservoir to find a leak in my car cooling system? (not planning to use it on ac)

I would not do it. Use a pressure tester. Pump it up and search. The reason for a dye in your ac system is because its gas that leaks. I have this pressure tester and it is worth the money. All the caps are metal or aluminium. https://www.amazon.com/dp/B08SQ97DGT?ref=ppx_pop_mob_ap_share
