coolant lines leading to EGR spacer
I had some mechanic take the lines off this system and plug them up. The idea was to reduce the heat into the engine. My understanding is that the system works to get the car to better operating temperatures at very cold temperatures. I can't figure where to hook the coolant line that runs right by the egr to the back of the engine. Please help any one!

There is a fitting screwed into the back of the lower manifold with a nipple on it. Attach the line there.

What side of the manifold?
What side of the manifold? Is is located near the Gas reserculaton hole. In what directon? Or what bolt is it next to on the torqueing sequences?

Those coolant lines are there to cool the exhaust gas before it enters the engine. if you still have an operating EGR valve, youmight want to reconnect them.

From what i understand the coolant through the spacer is designed for 2 different things.
1. To warm up the engine faster in cold operation 2. to cool down the incoming air and manifold when hot because the EGR valve is mounted on the other side, which exhaust gas is ALOT hotter than coolant. The coolant takes away the heat from the throttle body and circulates it back through the system.

Its near the back, passenger side of the lower intake. Not hard to find. Your mechanic eithier removed the nipple and installed a plug, or plugged the nipple with something. If you look down and back from where the coolant line comes out the back of the spacer, you ll be in the right area.
"Is is located near the Gas reserculaton hole"? No, not at all. Its on the lower manifold, not the upper. |

Thankx guys
I appreciate your replies. For some reason I can't find the nipple. I will check it out to night with better light.
84LX89GT is probably correct. That is what I have heard about the spacer. I have really cold winters so, it is especially important.

ok
What about warming the air in the spacer when the temperature is -20F.

I don't think the coolant lines are designed to heat up the upper intake. What would be the point of heating it up? Heating the combustion chamber and the cylinder heads would be important (thats why you have a thermostat) but heating the upper intake would serve no purpose other then slightly heating up the air. But the EGR valve is used for that purpose among other things.
Anyone agree or disagree?

Can't find it
Is the nipple running verticle? On the passenger side of the lower manifold I see a regular bolt that is in the torquing sequence. Then I see a larger bolt with a weld on it. I wonder if this nipple is threaded. These guys could of unscrewed it and ground off the nipple and then put a couple of welds to seal the hole.

Mach 1, you said cold air is your freind. Thats if your trying to build horse power, but Ford was thinking gas mileage and emission and smooth running.

hook them back up, as it was said before, the EGR gasses are by far hotter than the coolant going through those lines. I dont have mine hooked up, because my Intake doesnt have provisions for EGR so my valve isnt hooked up.
If your mechanic knew what he was doing in the first place, then he wouldnt have removed those lines. So now, as it sits, your intake is hotter than it was when the lines were hooked up.

Your best bet would be to pop into your local Ford dealer and purchase the part there. Or, just run down to NAPA, etc. and buy it from them.

Threaded nipple.
I need to buy an treaded nipple on the passenger side of a stock 5.0 lower manifold. This nipple holds collant that has already gone through the egr spacer. If some one would sell this to me for a reasonable price I would very much appreciate it.

Your local Ford dealer would probably sell it to you at a reasonable price. It cant be more than a few dollars.
