This Leak Plagued Me For Years!

I didn't mention it in the video but the issue I was having was the coolant was not traveling from the recovery bottle, back into the radiator, and over time that caused the radiator to run low on coolant and cause issues. I tried a new hose and radiator cap, but no luck! I would have sworn the issue was in my heating loop, which pulls off the engine coolant line, so I threw the dye in thinking I would find a hose was failing, etc...

I grabbed my UV dye from AutoZone, but it can be found online too. Check to make sure it is compatible with the fluid you will be mixing it with. I found that the UV light and glasses were not a huge help, but your results may vary. Working in a dark environment, which I did not have available, is a huge help!

After I found the issue was in the recovery bottle cap, I grabbed a new one off eBay for under $20 and had it switched out in literally under a minute. Happy to report the issue has been fixed, although I am keeping the dye in the loop as a safety precaution just in case! The only drawback is if you go to work on the cooling system it is slightly more messy, but a small price to pay for being able to spot leaks very definitively.
