intake manifold

[Stevebsy]

Don't separate the upper and lower intake manifold. Instead, separate the TB from the IM, (you can leave the coolant lines and throttle cables intact) and take the whole IM out as one giant assembly.

You need to first remove the bracket between the compressor and the intake manifold. 14mm wrench bolts. Once that's out, you can get at the manifold to head bolt with a socket and extension.

There are 7 bolts on each side that hold the IM to the Heads.

There are several other things that must also be disconnected - fuel lines, vacuum lines, electrical connectors, EGR tube to name a few.




My fingers are sort of pointing at the 14mm head bolts to remove between the AC and the IM

Here is a short list of items that connect from the IM back to the car somehow:


1. Throttle body to IM
(now start at the front right and work your way clockwise around the IM)
2. Carbon canister, two lines
3. Power Steering electrical connector
4. EGR sensor
5. EGR Tube
6. Two small vacuum lines
(now near the center rear of the IM)
7. 3x vacuum lines small dia.
8. 3 electrical connectors for I believe coolant temp, IAC, and TPS
9. Vacuum line to brake booster
10. 3x Fuel lines.


I should have the whole procedure written up sometime this week, message me if you get stuck on something.

There are some pictures and stuff here as well:
