Hi,

I have a 96 Sentra gxe with 157K miles. When the engine is cold and
running, I get a drip from somewhere near the beginning of the throttle body.
There is a coolant hose that feeds a metal tube that goes into the driver's
side of the throttle body,right behind a green spring that is right next to the
throttle lever.

The green coil attaches to the TB with screws. The TB is dripping from the
area the green spring attaches to. It doesn't seem to be leaking out of the
rubber hose. It seems to be coming right out the TB next to this green coil
thing.

Update : I have ruled out the hose as the source of the leak. I put newspaper
under the connection of the hose to the metaL pipe, ran the car, got the drip,
and the newspaper stayed dry. The drip was starting somewhere later on in the
flowpath. I then got a mirror and watched the throttle body area from
underneath. I saw the drip forming on the bottom of a brass-colored cylinder
which was inserted into the throttle body. This brass-colored cylinder has a
post sticking out of the middle of it horizontally, abnout an inch and a half
long. Looks like coolant is seepeing out around the edges of this cylinder.


What is this brass-colored cylinder ? Can it be replaced ?


Is it possible the TB is cracked and leaking coolant?

Any clues appreciated !

Sound like o-ring is leaking per post from Steve.
You'll have to disassemble the themowax accuator and changeout the worn
o-ring, check dealer, but they may only sell whole assy.
If they don't carry it, then remove and go to home depot and match the
o-ring.
