Cars - Coolant leak - not the water pump this time...

Just pressurize the coolant system with some air and watch for leaks. I
have seen tiny pin holes in hoses, corroded or deformed coolant pipes, and
more.
You can be creative and use a bike pump and a rubber tire valve in a hose to
create this pressure. ;-)
I have not tried this "tool" but it should work and most people have a tire
pump anyway.
If you leave the cap on the system you should not have to worry about
overpressurizing the system.

On my 1983 4 cylinder it was a head gasket leak. There was a groove cut out
by the coolant "maybe" that allowed the coolant a way out of the engine.
The leak I had was at the very front of the engine in the timing belt area.
I had not seen this before! 8^o
