Upon investigation, the technician may find a DTC P0410 indicating that there is a concern in the secondary air injection system. Cause Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump. Correction Replace the AIR pump and install a new inlet hose and solenoid tube assembly using the following procedure: 1. Prep vehicle. 2. Raise vehicle on hoist. 3. Remove shield covering AIR pump. 4. Remove hose and vacuum lines from pump and solenoid. 5. Remove AIR pump inlet hose. Do not re-use. 6. Disconnect electrical connectors from pump and solenoid. 7. Remove pump mounting bolts and pump. 8. Transfer isolators from the old pump to the new pump. 9. Install new AIR pump and bolts to vehicle. Tighten the bolts to 17 N.m (12.5 lb ft) 10. Route new hose assembly up between engine and fender. It should come up near the area between the battery and the coolant bottle. 11. Connect new inlet hose to pump inlet. 12. Connect old outlet hose to pump outlet. 13. Connect electrical connector to pump. 14. Connect electrical connector for solenoid to connector on the new hose assembly. 15. Connect the hose with the white nipple to the vacuum source hose. 16. Connect the remaining hose to the shut off valve. 17. Install shield covering AIR pump. 18. Lower vehicle. 19. Remove coolant reservoir nut nearest the battery. 20. Route new hose assembly between the battery and the coolant reservoir with the solenoid on top. 21. Install the solenoid bracket onto the coolant reservoir stud and reinstall the nut back into the vehicle. 22. Use a wire tie to keep the new hose assembly away from the engine. On four cylinder engines, tie to the AIR outlet hose. On six cylinder engines, tie to an available hole in the radiator fan shroud. |

Replying to: sonomaguy (Aug 07, 2005 10:37 am)  I would like to put a code reader on this truck, but the owner before me screwed it up somehow and it won't fit. I am sure my problem is fixable and I'm sure it's not helping my gas mileage or the truck running this way, but at this point I have no choice. Oh well.....

Replying to: taugust04 (Aug 14, 2005 9:33 pm) Two Thoughts ... 1.) Do you have an exterior Antenna? The Antenna needs a good ground at the bottom of the antenna to the body - As the vehicle is older, it may be loose, rusted, etc. I'd buy a new antenna , install it ensuring the inside/underside of the mounting hole is good an clean. 2.) Most radios "used to " have a "tuning" adjustment for AM. They used to be in the back - or perhaps if you pull off one of the knobs you will see a "pot" to turn. - check your manual. This adjustment helps with antenna impedenct matching between the radio and the Antenna .... Good Luck !! |

| I recently had my oil changed at a local lube shop and they stripped the drain plug bolt. I had to get a new oil pan (which they paid for). Can anyone tell me what the factory torque specifications should be for an oil pan drain plug for a 1995 Chevy S-10 with the V-6 engine. | |

I just found this forum...read through first twenty pages or so and noticed that two other owners were experiencing very poor fuel economy. I'm getting 19.2 mpg on highway at 60mph with no a/c. I have a 2000 Sonoma 2.2L with auto trans. I know it should get far better mileage; I had previously owned a '96 S10 2.2L and got over 27mpg with it! I noticed that the other two problems like mine received no replies so, I might be wasting my time! Engine runs strong, no hesitation, etc. and truck has less than 63,000 miles...I bought it just 2 weeks ago and my mechanic is scratching his head. What should I be looking for? Dealers just scratch their caps and shake their heads. What's wrong? Doe anyone have a suggestion where to begin looking?
