good write up there. I just might do this today and the TB coolant bypass if I can figure that one out too. anyone have a link to the TB coolant bypass or if there is a how-to on that?[/b]

all u need for this is i believe a hose splicer to connect the 2 hoses to each other. maybe 2 proper size hose clamps. it'll leak some coolant but nuthing major. u could use a red plastic cup to catch the fluid

Does anyone know what the torque specs are for the bolts holding down the intake manifold, the EGR valve, and the throttle body (if I end up removing the throttle body)? I just want to make sure it is torqued properly without over/under tightening.

I used to remember the torque specs for the throttle body but forgot.

I believe I found the torque specs for the intake manifold, thanks to a message Fly757 left in a previous post. Here is a direct quote pulled from that topic:

Quote:

-A torque wrench is always recomended for things like the intake manifold. You could get away with doing it by hand, but then you're taking some risks.
The upper intake manifold bolt pattern is as follows:

7 1 3 5
8 4 2 6

Torque 72-106 in-lbs. Work slowly and progressively, and in the correct order.[/b]

Now I just need to dig up the specs for the EGR valve and the TB. I'll post them if I can find them.

I'm in the process of doing mine now. That third hose under the TB is a pain in the ass to remove, I was unsuccessful removing it since it was stuck on the IM so well. Also, don't forget to take a vacuum hose to the EGR valve when finished to suck up any metal shavings/dust that may accrue in what's left of the tube prior to reassembling. I used a dremel cutting wheel on mine and it left some shavings and dust in the egr valve, nothing a vacuum couldn't handle.
