Been thinking about using dye to check for specific leaks before I attack the rear main seal and oil pan gasket. Since that area can be one of three different fluids for leaking given the coolant plugs, oil seals and plugs and proximity to tranny thought it would be good to confirm what we 'think' we know before we go through with the process.
Here's my question though. Obviously, I am looking for leaks from potentially three different fluids (coolant, engine oil, tranny oil). All I find during my online searches is the usually green glowing dye. I'm trying to find out if there are different color dyes so that I could put a different one in each fluid for more specific answers.
Anyone know anything about it?
