When my car sits in garage, the radiator (which is about 3 years old) leaks a few drops onto the floor. Probably about 3 or 4 drops a day, maybe less, but it's a noticeable puddle. Very annoying. Leaking on the drain plug (driver) side.

I've had it to the local radiator shop and the guy pressurized it but could not find leak.

Anybody got any suggestions for locating a small leak?

thanks

Dust on some baby powder or talc in the general area where you think the leak is, and the source/path of the leak will become very apparent; washes off with plain water. Good way to find mystery oil leaks too. :thumbsup:
