When I messed up on my first ever coolant change and overheated the inline
motor in my van, causing a headgasket failure....I found the leak by
removing the sparkplugs and putting air pressure into the pressure bottle
of the cooling system...then I took a piece of conduit and listened
carefully at each spark plug hole....found the leak, no problemo....on my
motor's installation you could also look right down into each cylinder and
see coolant pooling on the piston top....
