1999 EuroVan MV spark plug replacement question

[Brunocerous]

Hi all,

This is my first post after purchasing a 1999 EuroVan MV. This weekend, I decided to start replacing all the fluids and filters, as well as the spark plugs in the VR6 AES engine. (Who puts an exhaust manifold IN FRONT of the spark plugs?!)

I watched a couple of videos on how to change spark plugs, and in my excitement, I neglected to photograph the engine before I removed the airflow tube and the attached hoses. Now, I can't recall where a hose connects.

It's the one that moves diagonally down from the top left corner in the first photo. It's underneath the air tube in the other two photos and the opening faces the camera.

I feel silly asking but if anyone knows, I hope someone here might be able to help.

Cheers,
Bruno

Also, yes, I know the heater core has been bypassed. It's on my to-do list.

Here are better photos with the wayward hose circled.

That hose is routed under the intake pipe, across the engine to the back, and attaches to a T fitting underneath the blue sensor on the heater hose (that has been bypassed.)

You should have a vacuum hose diagram of a sticker on the radiator crossbar I think
