Heater Control Vacuum

mr spree · 10-12-2009, 03:04 AM

I'm using the truck intake and the vacuum port on the back of the intake is being used for the brake booster....where can i get another vacuum port for the round canister ball for the heater controls?
This is a 1st gen btw...idk if its different then 2nd gens
thanks for any help!

Put a "T" in the main vac line.

mr spree · 10-12-2009, 01:41 PM

wheres that main vacuum line? lol

CatDaddy52 · 10-12-2009, 02:10 PM

...the one to the brake booster.

mr spree · 10-12-2009, 02:59 PM

so..that wont mess anything up? idk how vacuum really works, especially with this round ball reservoir... but having that round ball thats for the heater controls connected to the same line as the brake booster wont do anything to the break booster?

tippmann243 · 10-12-2009, 05:39 PM

if you dont want to "T" into the booster line you could always drill a hole and ass a fitting to the backside of the intake

LS2Sonoma · 10-12-2009, 08:02 PM

arent there other ports for the vacuum lines on your intake? and that ball is your vacuum resevoir

mr spree · 10-12-2009, 08:24 PM

There are but i dont im not sure where i could find the fitting for them. Theres one on the intake that looks like a fitting but seems i would have to break off the top of the fitting but idk if thats what its for....ill figure something out

turbobandit · 10-13-2009, 02:56 AM

look around the throttle body.. there should be a couple. Also look under the big line to the brake booster, is there another smaller nipple? near your MAP sensor? (speed density sensor)

mr spree · 10-13-2009, 03:13 AM

well there is a line coming off the throttle body, which the truck intake already has, could i use that?

Yup. As long as it's not the coolant line~ There is an in/out (w lines) off the tb for coolant.

Is that line manifold vacuum or ported vacuum (just above the throttle plate)?

mr spree · 10-14-2009, 03:54 PM

Yea there was a plastic line coming off the passenger side of the intake i just had to twist the top off so ill use that for the heater controls! thanks guys

that is for the pcv. it connects to the passenger valve cover

mr spree · 10-14-2009, 09:05 PM

^^ yea and the truck intake already has one so i just plugged that one on the TB

LS2Sonoma · 10-14-2009, 11:37 PM

mr spree · 10-14-2009, 11:43 PM

yes the truck intake already has one right there for the line going to the valve cover. same as the driver side. the tb is off a ls1 intake which doesnt have one since its on the tb

LS2Sonoma · 10-14-2009, 11:49 PM

oh yes, right... newer truck intake? the ones i have are older and they use the line from the tb

mr spree · 10-14-2009, 11:54 PM

04 one? it had an electronic tb before which didnt have any lines to it

LS2Sonoma · 10-15-2009, 12:24 AM

yea.. makes sense. guess im not so familliar with the truck stuff. come to think of it, one of the intakes i have here is etc, ive just never looked at it that close... so there

mr spree · 10-15-2009, 12:37 AM

haha

mr spree · 10-15-2009, 06:49 PM

This one is for the heater control right? Its connects to the round canister ball?

What are these two for then? The one coming out of the wall and the other one goes into the bundle of wires.

LS2Sonoma · 10-15-2009, 08:50 PM

the small black line is for the heater. the big one looks like the booster line

NCRides · 10-15-2009, 09:16 PM

where does the hose in the top picture lead to ? it doesn't look familure as it's been over 3 years since I took my truck apart and it isn't on my truck now
the bottom picture has the heater control hose (small hose on left coming out of harness) it should connect to a check valve with a tee that looks like this, the check valve is probably still hooked to the old motor

the black side of the valve goes to the intake (the bigger line) the other two go to the line you are holding and the ball shaped resevior
the larger hose to the right is the windshield washer hose it goes to the washer pump mounted on the tank

mr spree · 10-15-2009, 09:36 PM

The one in the top picture leads into the firewall just under the break booster. And yea i did find out that the line coming from the firewall in the 2nd is for the windshield hose. I have a check valve that i just bought but its only got 2 lines on it. Ill have to go buy one sounds like it

The line in the first picture was hooked up to the cruise control vacuum thing

LS2Sonoma · 10-15-2009, 10:31 PM

lol its been three months since i took apart my first gen and i cant remember anything!

there should be another small black line thats for your heater... please dont hook up your squirter to your intake! haha
