I'd like to hook up a vacuum gauge to the intake manifold of a 1997 chevy 3/4 ton 4-wheel drive pickup with a 5.7 L engine but it doesn't seem to have any port through which to do this. It is a two-piece manifold, the upper portion being plastic on top of which is the throttle barrel and fuel injection. How is this done these days?
The last time I did any vacuum testing it was 20 years ago and on a Datsun with a simple carburator.
Just put a temporary Tee in a main vacuum source and remove when done.
Thanks.
Ah, but I can not find such a tube. All the connections to the manifold seem to be made through various modules containing sensors, switches, or valves. There doesn't appear to be such a simple "main vacuum source". I'm the kind who's often unable to "see the forest for the trees", though. The only real candidate I've found so far is the fat hose supplying vacuum to the brake assist. It's so huge I assumed there would be something smaller. Should I just funkup a Tee in that?
There should be a line running to the Engine coolant sensor at the front of the engine one of those is the feed for the switch and will be fine!
WTF ?????
Sorry if I went over your head. Maybe bringing it into a shop where someone could point it out for you would be best.
2) then you can explain this 'vacuum line to the engine coolant temperature sensor' nonsense:
3) then again, you probably can't, since insults seem to be your stock-in-tradeI didn't mean to insult anyone and I replied to the original poster at the end of the thread. I honestly thought he did'nt understand. Sorry!

Except for the lack of posting ediquette.
Learn to include the post you're reply'n to. So's we don't have to read the entire thread to figure out that you've pissed GG off and now you're try'n to make amends.
by the way......
Do all vehicals have this vac line running to the Temp Sensor that you told the OP about? jest curious.

yeah, that's a hoot.....................
Yes most vehicles have a water temp switch that has vacuum going to it. NOt sure how to include the post i am replying to i just hit reply. I'm on AOHELL! LOL!
water temp / vacuum switches went out with carburetors
modern engines have coolant temp sensors with WIRES
Original poster was referring to 1997 vehicle.
what part of 'went out with carburetors' (1987 for Chevy trucks) is so hard to fathom ?
He's looking for an accesible vacuum port on a 97 truck
My first choice would be putting a 'T' in the line to the MAP sender, if it uses one; second choice, a 'T' in the line to the power brake booster.
You're NOT gonna find a vacuum line going to the CTS, and there are NONE of those Water-temp-to-vacuum switch things on any post 1990 GM engines
I don't think there was a carbureted vehicle made since:
the late eighties?

PS I guess Marsh got his bite! LOL!
