oil/coolant tracer

where could i find some oil and coolant tracer. i have a bit of a leak and i would like to figure out where its coming from. could there be something else i could use to help me find the leak instead?

how would we know man! get on ur knees and look! there is heater lines and oil pan, waterpump, ETC dwon on the motor so look around and u will find!

there is a chemical you dump in your oil/coolant and use UV light to detect.

Gotta flush or change your oil after tho.
