2. Fuel Filter Change The fuel filter needs to be changed every 15 20 000 miles under extreme driving conditions If you re hauling aSS like I was then follow that interval 1 First you need to raise the vehicle where the driver s rear wheel is off the ground the filter is located under the body in front of that wheel 2 Relieve the pressure form the system You can remove the gas cap to do this but it s best to unplug the fuel pump by the wiring harness directly under the body below the tank fill tube while the car is running and let it stop It will take a second or you can give it a little gas to until it chokes 3 With the gas cap off remove the bolts to the harness holding the filter in place 4 Then use a set of pliers and a flathead screwdriver to unhook the hoses from each end This is a little tricky but give a good look to them and you ll see how they come off Remember There is still gas in the lines and it will pour out so have a pan handy and then keep it there until the gas runs out It helps to tilt it and remove the leftover gas in the filter 5 Reinstall the new one in the reverse order making sure it is in the right direction and the hose are secure to the filter 6 Reconnect the harness if you chose to disconnect it and crank the car Turn the key to the Run position and let the pump prime the lines before cranking 37 EXHAUST EGR Valve Replacement One of the common repairs to the B body LT1

You know when you have something nice there will always be someone who will mess it up I found this out shortly after I bought the car Someone tags my side view mirror and makes it face the other direction If this wasn t enough I was rear ended a few weeks later with a total of 12 000 plus in damages No it wasn t totaled only because the bent rear axle wasn t discovered until the bodywork was finished To keep a long story short within the next few years I had one more wreck hail damage and had a new transmission put in any finally a pine tree totaled it on my day off in June 2003 Yes it was a few banner years but I never gave up and still loved the ole girl and do not regret purchasing the car In conclusion I always wanted to make a reference guide for beginners and just a helpful little tool for anyone who owns a B body I never had enough information to go by or enough knowledge to back up my findings Now I have learned a lot more and have plenty of hands on experience with many procedures and many more to come If this guide helps at least one person work their way through a repair or modification then I will be happy I tried to include all credits to everyone s comments and procedures I used in this manual but if I left anyone out or made a mistake of any kind let me know and I will make the appropriate corrections Please enjoy this guide and any feedback suggestions new procedures corrections problems praises ins

10. If they are old you may want to replace them Now is the time to do it Remove the 3 bolts that hold the Optispark in place Pull it straight out There is a shaft that connects the Optispark to the Cam gear This may or may not come out with the Optispark At this point you should look at the old Optispark and make a mark of where the notch spline is This will assist you later This would be a good time to put some gasket sealant on one side of the gaskets and place them on the water pump so they can dry This will make reinstalling the water pump much easier With the old Optispark to compare rotate the shaft on the new one until they match up I found it easier to insert the shaft on the cam shaft and then sliding the Optispark on top of it IF there is any gap on any of the 3 mounting screws you probably haven t lined the Optispark up correctly with the spline on the shaft It should slide all the way on with no gaps on any of the mounting areas Tighten the bolts but do not over tighten Run your vacuum lines The clip goes on the alternator bracket MAKE SURE the hoses are going to clear the belt The hose that has the filter and regulator is the vacuum supply Poke a hole in the rubber bellow on the top and push the L into it Put a T or something similar on the drivers side intake manifold and hook the vacuum hose up Reconnect the plug wires Reinstall the 3 bolts on the balancer Tighten the bolts to 60 Ft lbs Make sure y

It will cause hesitation stumble and hurt gas mileage It s an easy fix but a little pricey and annoying Get a new one or get the 6 speed EGR valve from the F Body LT1 They tend to last longer and are the same price anyway So buy it Go ahead and get the solenoid as well they re not that much and it s good to replace it while you re back there 1 The valve and solenoid are located on the back of the engine on the driver s side The valve looks like the one to the right 2 It is held on by two bolts and connecting by hoses to the solenoid The solenoid is connected by bracket to the engine that is secured a bolt 3 Be sure to make note of how the hoses are connected while removing it 4 Remove the old gasket from the valve and engine and replace it with the new one and install in the reverse order EGR Campaign Letter If you have a 1996 with less than 100 000 miles on it and fewer than 10 years old you may be eligible for a free replacement Read the campaign letter at this link http www impalaclub com naisso egr pdf AIR Pump Delete Note 1996 must be reprogrammed It will also blow your hood light they work off the same fuse I also believe it will give you knock on cold starts as well QaloSS GM TSB for Air Pump Removal http www impalassforum com tech engine air_pump air_pump htm Technical Water in AIR Pump and or DTC P0410 P0412 P0415 P0416 P0100 P0101 P0102 or DTC 48 AIR System Dis
12. a few whacks of a hammer or wrench and they ll come out If you flatten the threads don t worry the new arms come with new bolts Now the hardest and most time consuming part of the replacement is the bushing removal Follow Noel s instructions I personally used this procedure The only thing I recommend is to use a sawzall A jigsaw is worthless and be prepared to hammer a while getting the bushing back in I recommend the Metco tool because you tend to beat the mess out of the new bushing Also when you use the puller to remove the shaft from the middle of the bushing use a bolt laying around and drill an indention in the tip and let the bolt do the pushing and not the tip of the puller bolt You 27 don t want the place you rented it from or yours to get damaged and the one I rented was a little thin and wanted to sink into the tube Rear End Bushing Removal By Noel Haro Background This came about when installing my new set of BMR lower control arms When it came to the bushings I wanted to replace them but I didn t buy the Metco tool cause I d probably only use it once or being the cheap bastard that I am D I looked around my garage to see what I had to remove them Read on and you ll see what I did Now this tip came from someone whose name escapes my mind but comes in very handy When removing the control arms there s no need to disconnect the brake lines and therefore no brake bleeding 1 Jack up t
