"How I Do It" Finding the Source of a Leak
Finding the source of a leak can be a frustrating experience. The technique described here will help you track down the source of a fluid leak, such as antifreeze, engine oil, or transmission fluid.
BABY POWDER!
You could also use talcum powder or corn starch. To illustrate, the following photos are of a leaking transmission on a 65 Chrysler. I had chased this leak for a while with no success.....probably because there are too many things to tighten and too many things with the potential to leak. Then I thought of the powder.
The passenger side of the transmission case with powder. No leaks here. The park pawl assembly showing a slight leak but no leaks from the park cable. Also, no leaks at the pan. The rear cooler line, no leaks. The powder shows what is leaking and equally important, what is not leaking. The front cooler line area......a problem here. Closer inspection showed the leak comes from this fitting. Back |
