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.

what about the one at the bottom of my picture, what is that for?

duboisr

It goes to the bottom of the throttle body .the short hose for it is a formed 90 degree bend rubber part.

That's what I did.

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?

Bucrx7

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.

ok, i understand that now.. but im still wondering what the hell is the nipple on the bottom of my picture? its on the middle housing driver's side....

Thanks for the help guys...

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.

ejmack1

so i dont do anything with that one right? just leave it open? Is it a coolant line, or a vacuum line?

Marshall

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

ejmack1

ok so I block that one off too right?

Bucrx7

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.

ejmack1

ok, I have the rear housing nipple and the waterpump nipple plugged, but what about the nipple on the middle housing.

Bucrx7

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?

ejmack1

yeah totally understand all that... I just need someone to tell me what the nipple on the middle housing goes to, that I have circled on the picture..

THanks

Bucrx7

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

ejmack1

I got rid of the hardpipe already, that nipple that I have circled is on the side of the engine on the middle housing....

Bucrx7

The red circled between the oil neck filler and oil filter?

ejmack1

yes... am going out to the garage to verify its part of the engine.....

ejmack1

yep, cast into the middle housing....

Bucrx7

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

Are ya SURE that isn't the oil dipstick tube?
