Chevy vacuum routing vaccume - 1990 Chevrolet K2500

The vacuum lines on a 1987 Chevy S10 Blazer are responsible for routing vacuum to various components such as the brake booster, EGR valve, and other systems.
A vacuum line diagram for your specific make and model of Chevy S10 Blazer can be found in the vehicle's service manual or in some cases, it can be found under the hood on a decal or sticker.
If the vacuum lines are loose, cracked, or damaged, it can cause various issues such as rough idle, stalling, poor performance, or even a failed emissions test.
It's best to consult the service manual, a professional mechanic or the dealer for proper diagnosis and repair of vacuum lines issues. These lines are crucial for the proper operation of many systems in the vehicle, so it's important to fix them as soon as possible if they are found to be damaged.

Thank you for using FixYa, have a nice day.

There should not be an open vacuum hose. Look around it for a place it may have come off of. If there is enough play, you can trim a quarter inch of the end, if its stretched out, and replace it back on its fitting. If you really cannot find where it goes, just plug the end with somthing till you figure it out. A small screw, or similar usually works.

under the battery is where you need to check first,then follow it down around the right front wheel well,

The vaccume hose routing should be on a sticker on the radiator shroud under the hood.You may need a temperature senser to fix your problem.
