This is the only one I'm not 100% on yet. This rubber 90-degree hose is for is vacuum, not coolant, right?

May or may not be related: I have a monstrous coolant leak. Seems to be from the thermostat housing area.

Can anyone tell me about that last hose pictured? I got the coolant leak figured out, so this is the last thing keeping me from firing the truck.

If it is indeed vacuum then either the evaporator service port or brake booster. Do you have 2 coolant hoses hooked up to your PVC valve?

On my 99 this hose

It feels as if every time I figure out one thing, I lose confidence in another. Here's where I am right now.




Feeling solid that A to A is correct.
The diagram above indicates B to B is correct, but is it?
I'm not sure where C goes.
From the diagram above, it sounds as if D should go to G below. Is that right?



E had been going to a T fitting that joined with A from the intake and was plugged into B on the PCV valve, but that just feels wrong. That T fitting has me confused. kd4gij, you're saying it should go to A on the intake, but that contradicts the diagram above. I'm not doubting you, but if that's not how your truck is set up, it may mean other info on that diagram is incorrect as well.


Not sure where F should go.

Again, thank you all for your help.

Thanks to everyone for all your help. Tonight I was finally able to start my truck and hear it run for the first time since January. Today was a good day.
