Engine Performance problem
1999 Cadillac SLS V8 Front Wheel Drive Automatic 115000 miles
well I just had a smoke test done on my 99 seville to troubleshoot a p0440 code. The shop told me that there were no leaks but my evap system was malfunctioning due to the canister solenoid vent not opening and closing everytime. I went to the dealership and bought the solenoid for around 40 bucks, was wondering what the exact procedure for uninstall/install is for this is. Will I have to undo the bolt for the mount or will it just slide off? The bolt is kinda hard to get at and im thinking about just having the shop put it on for me, ballpark estimate for labor is around 50 bucks.
The service procedure is calling for removal of the bolt. If it looks like you can slide the valve off the bracket, the do so.
Evaporative Emission Vent Valve Replacement
Caution: Provide additional support when a vehicle is on a hoist: " Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.
" Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.
Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.
Raise the vehicle.
Remove EVAP vent valve retainer clip (1).
Disconnect the EVAP vent valve electrical connector (5).
Disconnect the EVAP vent valve fresh air pipe.
Remove the bolt (3) from the EVAP vent valve solenoid (4).
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Important: Assure that the anti-rotation tab on the bracket is inserted into the lower hole of the frame rail.
