View Full Version : Help Identifying Parts/pieces (please!!!)

02-20-2008, 08:52 PM
alright guys my motor is pretty much ready to drop, its a 93 SR Read Top, i just need help identifying these last few things, there are four nipples that need hoses, two are coming off of the throttle body, one is coming off the back of the intake (http://www.zilvia.net/f/showthread.php?t=178338#) manifold, and the fourth is coming off of the coolant water neck that sits underneath the intake manifold, the nipples that come off of the throttle body have rust/corrosion on the ends as does the one coming off of the water neck so im thinking these run coolant, the one at the end of the intake manifold has nothing so i have no idea what so ever. So i just need to know where these go or in what way to connect them to each other...i have pics... thanx guys, this is now the only thing keeping me from starting her :wtc:, +rep for those that offer legitimate advice...

look in the "Engine Lubrication & Cooling Systems" section of the FSM. to make it easy for you, i've attached a snapshot of the FSM and a coolant routing diagram. mind you this is for an S14 so it might not be the same for your setup, but should be relatively similar.

the nipples on the TB are for coolant lines. one dead giveaway is the corrosion on the nipples. have a look. i was too lazy to edit the screenshot, but you get the idea.

i don't think the nipple in the back of your mani is for coolant though. it is a vacuum source for your brake booster.

do you have the entire FSM, apparently i only have the Engine Mechanical part of it (no wonder i couldnt find the cooling section)

lol...i was looking at the pics closer and noticed this:

lol that's probably not air tight. go to autozone and purchase a vacuum block off nipple thingy. that contraption looks like it's about to pop off.
