How to Clean the Throttle Body on a Chevy Colorado

by Russell Wood

The Chevrolet Colorado is the successor to one of Chevy's most popular small trucks, the S-10. Since its introduction, the Colorado has seen success as well, and lots of happy owners are putting high miles on their pickups. When a truck gets older and logs a lot of miles, perform simple maintenance to keep the engine running at its best. One thing that helps is cleaning the throttle body, which will help to lubricate the linkage as well as make sure that no gunk or residue gets into the engine.

Step 1

Pop the hood on the Colorado, and locate the throttle body.

Step 2

Disconnect the black plastic tube that runs from the air filter to the throttle body, using a flat-head screwdriver to unscrew the hose clamp that secures the tubing to the throttle body. Then pull off the plastic tubing.

Step 3

Place a shop rag underneath the throttle body to catch any excess cleaner. Take the can of throttle body cleaner and insert the included straw into the end of the nozzle. Point the straw into the throttle body, and lightly spray the cleaner. Hold down the nozzle only in short bursts.

Step 4

Hold open the butterfly on the throttle body by pulling back the throttle body linkage, opening up the passageway to the engine. Lightly spray the throttle body cleaner into the throttle body in short bursts.

Step 5

Wipe off any excess cleaner with the shop rag, and clean any painted surfaces, if any, that the spray contacted. Reinstall the black plastic tubing with the flat-head screwdriver.
