Have 2005 trailblazer check engine light on and code they gave me is P0410. secondary air injection sytem. where is this located


If you have a "Air pump installed on your TB then you need to replace pump and or check to make sure that the hose's are all connect to it prior to replacing the pump which is dependisng on which engine you have on the lower left side (passenger)
Models Affected
1999-2003 Chevrolet Blazer, S10
1999-2001 GMC Jimmy
1999-2003 GMC Sonoma
1999-2001 Oldsmobile Bravada
All with 2.2L or 4.3L Engine (VINs 4, H, 5, W -- RPOs LN2, L43, L35)
Condition
Some owners may comment on the check engine light being illuminated. Upon
investigation, the technician may find a DTC P0410 indicating there is a concern in the
secondary air injection system.
Cause
This concern may be attributed to water that 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 17N·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.

What is the hose going into the top of the water pump and can you replace the nut/connector at the end that goes into the water pump. I thought it was an air condition hose but there is water comin out of...


the hose at the top of the waterpump is a heater hose,be careful not to break off the fitting in the water pump,its made of cast aluminum,replace the fitting with the one with no slots in it

Secondary air injection system


This is a pump that sits underneath your front bumper on the passenger side. It is about the size of a baseball and has two hoses going into it. I would suggest you replace it yourself as it would cost you about $360.00 if you were to go through the dealer.

Water intrusion is what will typically kill these electric pumps. There is a Technical service bulletin (#04-06-04-015) Regarding this problem, according to the tsb, you will need a new pump and there is a hose assy. #12590627) that has you reroute the pump from future water intrusion or it is guaranteed to fail again.

Although I have had water in the pump I did not see any indication of the inlet hose as the cause. It was suggested that the one way metal check valves ($15.00) that mount to the rt & lt exhaust manifold are worn and allow water from the exhaust to get sucked back into the pump. I first replaced the pump and within a week of dry weather driving the light came back on. I checked the pump and it was again full of water. I just replaced the valves which had deteriorated on the inside. So hopefully this will eliminate the problem. Note - The valves are impossible to remove without removing the 1/2 tubes (held on with 2 nuts) they are attached to the manifold with. The valve threads seize to the tube thread and had to be clamped in a vise to remove - I actually had to hacksaw the valve section to get it off the pipe. Careful as not to damage the threads.

Good luck and try autopartsdirect2you for a new pump and it has life time warranty.

Where is the water pump located on a 2000 Saturn


Standing on the passenger side of the car with the hood open looking down into the engine bay you will see the serpentine belt. If you have air conditioning, look directly below the air compressor pulley, the next one down is the water pump. Another easy way to find it is to find the lower radiator hose (again on the passenger side of the engine) and follow it to the engine block, the pulley where the hose meets the block is the water pump (not the pulley, but what the pulley spins is the pump).

Diagnostic Aids
  • Low system airflow can cause an intermittent complaint. Inspect for the following conditions:
    • Any restriction in the exhaust system that may produce back pressure
    • Pinched, kinked, restricted, or leaking pipes, hoses, or fittings
    • A restricted pump inlet hose, duct, or filter
    • Pinched, kinked, restricted, or leaking vacuum lines
    • Heat damage
  • A short to voltage in the pump relay control circuit can result in the AIR pump running continuously with the ignition OFF by back-feeding to ground. This will eventually result in pump failure.
  • An AIR pump that had become inoperative and had shown indications of having exhaust gases in the outlet port would indicate check valve failure.
  • Notice Do not operate the AIR pump for more than 60 seconds. Continuous operation of the AIR pump in excess of 60 seconds will damage the AIR pump.

    If the DTC cannot be duplicated and is determined to be intermittent, reviewing the Failure Records data can be useful in determining when the DTC was last set. Also refer to Intermittent Conditions

Changed thermastat,spark plugs,new intake car is over heating during shifting is this my water pump 99 civic lx 5spd


can't necessarliy automatically blame the water pump, check entire cooling system related components , check air flow through radiator and condensor, often overlooked and plugged with bugs and road debris, check all hoses for condition especially for a collasped bottom hose due to your opening system to R&R thermostat... you may have to bleed air from your system ... check coolant condition for specific gravity.. clogged internally radiator, check flow with cap off engine cold pressure relieved watch flow to see when thermostat is opening... should have increased contant flow. check belts for proper tension and condition.

I have a 99 suburban 5.7, and im gushing fluid inbeetwn the thermastat and the air condition pump


You either have a leak in the hose or a hole in the themostat housing. Check the hose for holes first then tighten the hose clamp. If it still leakes then remove the hose from the thermostat housing and replace both the thermostat and the thermostat housing. Any more questions please ask.
