Coolant hoses under the manifold....

1) there is the nipple on the drivers side, middle section of the engine the points upward...

2) then there is one on the passenger side rear rotor near the firewall that point upward....

3) then there is one on the water pump that points towards the rear

How do these all connect... i do not have them running through the Throttle body anymore, am I missing a nipple somewhere?

Water pump to the metal tube in front of rats nest ,to the front of the throttle body (lower ) . Then from the throttle body hot wax rod fixture to the nipple on the rear housing top. . Three rubber hoses , 1 metal tube, through the throttle body . Garfinkle pipe plugs the water pump house nipple and the nipple on the rear house, he removes the hot wax rod fixture and the lower nipple from the throttle body . He removes the metal tube from the rats nest also.

ok im still confused... the nipple at the waterpump attaches to the hardline, the hardline attaches to the throttlebody, the throttle body goes to the nipple in the top left of my picture... how can the nipple at the bottom of the picture go to the throttle body if the one from the waterpump is already going there....

sorry for the confusion.... should i just block them off? and what exactly would i block off? all three nipples?

Ok block off the nipple from the rear housing. Then block off the nipple from the water pump. Then you can leave the hardpipe and throttlebody nipple open. So you're only blocking off 2 nipples, rear housing and waterpump nipple. Leave the rest the way it is. Since you blocked off the rear housing nipple coolant doesn't go into the TB and doesn't go to the hard pipe. Since you blocked off the waterpump nipple coolant doesn't go to the hardpipe and to the TB. Get it? hope this helps.

The bottom circle one? It is connect by a small rubber hose that goes to the bottom of your TB. Take a look at your TB.

its one of your throttle body coolant lines. There is a rubber hose that connects it to the bottom of the throttle body.

After you block off the rear housing nipple and waterpump nipple you can leave the 2 nipples on the TB open. It's for coolant, and by blocking these nipples you just did the TB coolant elimination mod.

You don't need to plug that. Below is how the coolant flows.

rear housing nipple ---> top right TB nipple ----> bottom TB nipple ---> HARDPIPE NIPPLE ON THE MIDDLE HOUSING ---> waterpump nipple. Get it?

Are you talking about the hardpipe? The bottom circle? The hardpipe leads to the waterpump nipple. But since it plugs nothing will go through.

That pipe is a coolant pipe that leads to the waterpump nipple. Trace it down.
