Vacuum tube placement?

atsomepoint · 09-08-2007, 07:50 PM

Also, there is a vacuum hose that runs off of the unknown part that doesnt go anywhere (just left hangin open?)
Any idea wat thats about? (Again see pic)

Yes, I have some ideas about all this.

Thats some hack shit. Buy a new BVSV, hook the charcoal canister up and throw that thing away. It looks like a stock VSV that connects under the intake manifold but the connector is way different.

OK. I'm back today. The wired vsv is for the heater water control valve.

You can 'save' the bvsv by using a hacksaw, and carefully cut away the support material between the 2 ports. Then you can place the vacuum hose on there. It will be a bit larger port, but the hose will fit, and stay in place. (ask me how I know this, for 5 successful years and going).

There are vacuum diagrams on this forum. do a search.

Ok, thanks guys. After many a vacuum line diagram i got almost everything back how it should be. And now my cruise control works, who knew.
O, and i took the hack saw to the bvsv just like you said and it worked like a charm.
But that vacuum switch that i have a pic of (heater water control valve?) is no connected to nothing whatsoever and i cannot find a diagram that includes it or any open spots for where vacuum tubing could go.

I've never found a diagram either. The long vacuum line comes from a "T" off the cruise control line.

The short one goes to that water valve mounted on the bracket at passenger firewall. The coolant 'always' flows to heater core...except when you have the temp on the dash set to 65*, then the vsv gets power to shut off the water flow.

for a bit colder a/c operation.
