It is probably the heater hose that connects under the front
ot the intake manifold to the back of the water pump. That
is the most popular place. It run down the top of the block
and drip by the bell housing. IIRC, it requires that you
remove the intake manifold to replace it. Not a bad job for
a mid level DIY'er with a decent assortment of tools. It is
also a good time to do other maintenance like clean the EGR
ports, clean the throttle body and the IAC as well as
replace the thermostat, antifreeze and spark plugs along
with any hoses that looked a bit distressed with age. You
can also get a good look at all the vacuum hoses and tubes
for the PCV system and replace them since they tend to fail
or plug as the vehicle gets older. You might also want to
clean the MAF in the air intake while your hands are dirty
with it. You will of course need about $50-$100 in parts
and solvent to complete what is about 4 hours labor for a
DIY'er if all goes steady and well. Your CV should run much
better when you're done.
