Coolant Leak. From Radiator Hose?

[RetroJohnny]

Hello everyone, So I've been keeping close track of my collant issue lately, I actually just replaced the thermometer and the radiator itself, but it still leaks coolant on occasion. And when it does it leaks quite violently. But I can't mark a for sure place where its coming from. Is it this lower radiator hose that isn't tightened all the way? Or could it be something else from within the engine? It only happens if the car is driven rough and at high revs. But the temp isn't raising, it does not surpass 190 degrees. As you can see in the photo there is collant all over the left side of the engine, from my perspective looks like it's coming from that hose that connects to the the engine. Any advice? Thanks!

First off- I'd degrease the whole area, and blow dry or ShopVac dry. Then- get THIS for $8 at your FLAPS. You might need THIS SET, TOO. They got it for oil & AC as well.

 

Reusable, real handy, big $$$ saver- no more guessing.

 

              $8.00                                 $15.00                               $8.00

 

MAYBE- IT'S...

Thanks for that UV dye info, I'll check it out for sure, especially for oil stuff. And I'll tighten thathose then if that doesn't work I'll check out that bypass hose!

I think that the easiest way to solve this is to go to one of the auto parts houses, (O'Reilly's, Autozone, et al) and rent a radiator tester, pressurise the radiator and look for where the coolant is leaking from.

Be aware, the Auto-Pro coolant dye ISN'T for cooling systems using Dex-cool, the GM coolant of choice in later GM vehicles.

Something about it won't fluorese.
