Timing on 69 buick 350 were do marks go up down or meet in middle timing marks 69 buick lasble

the timing is computer controlled,the only timing marks are on the cam where the timing chain is,,check compression on all cylinders,because getting to the timing chain is a big job,its behind the water pump,here are some videos for you, 1986 cutlass 3 8L timing chain replacement

the fuel level sender is inside the fuel tank, part of the fuel pump assembly. did you or was the tank replaced before??they may have bent the float arm on reassembly . you can buy the sender from your parts supply store .you will have to drop the tank to do this it clips onto the side of the pump assembly. run it almost dry first as the tank is big n very heavy even 1/4 full. you can try to bend the old arm

but its very hard on the "sender" as for level indicator full to empty, think of the shape of the tank narrow at top to widest point in the middle (full to half) wide middle to narrow bottom( half to empty)

its just an overall volume thing

How do you know the timing needs to be set? Check library for a repair manual. Usually the timing marks are marked on the front balancer pully mark the designated mark with something like whiteout so you can see it properly with a timing light.

From this chart - I think you may be misreading the number - 3970010 is possibly the actual number: Which makes the engine pretty old 68-72 350 V8 - 4 bolt main. I included past this number so that you can see that the number you posted doesn't actually exist. And thus my conclusion that the 9 is most likely a 0. Hope this helps. 3970010 350 69 Corvette late 69,4 bolt main 3970010 302 69 Camaro Z/28,Late 69, 4 bolt main 3970010 350 69-79 Truck 2&4 bolt main 3970010 350 69-79 Pass,Chevelle,Camaro,Nova,MonteCarlo 2&4 bolt main 3970010 350 70 Corvette 300,350,370 HP 4 bolt main 3970010 350 71 Corvette 270,330 HP 4 bolt main 3970010 350 72 Corvette 200,255 HP 4 bolt main 3970014 350 69-77 Pass,Chevelle,Camaro, Nova,MonteCarlo 2 or 4 bolt main 3970014 350 69-79 Truck 2 or 4 bolt main 3970014 350 72 Corvette late &undefined;72,200 HP,255HP 4 bolt main 3970020 307 68-73 Pass,Chevelle,Camro, Nova 3970020 307 69-73 Truck 3970024 307 69-73 Pass,Chevelle,Camro, Nova,Truck 3992386 327 68-69 Pass,Chevelle,Camro, Nova,Truck Large Jounal

The middle or slightly below the middle mark is where the needle should be when the engine is up to operating temperature. The middle mark is about 200-220 degrees which is absolutely perfect for GM.

The 2 sprockets have small round marks on outside edge of pulleys, they should meet/align in middle, as in facing each other.

Timing mark's on cam and crank should meet, if you did not put distributor out, just set timing gear's as shown, it you did pull it out, stab distributor 180 off, hope this was very helpful.

diaconnect the vacuum advance, and loosen the distributor hold down bolt just enought so you can turn the distributor, at idle turn dist, to advance mark on the harmonic damper to spec, either found on a sticker under the hood of from manual, need a timing light, tighten dist bolt ,

THE RELAY FOR THE ABS SYSTEM IS IN THE UNDER HOOD FUSE/RELAY CENTER. IT IS LOCATED ON THE FIRE WALL UNDER A PLASTIC COVER MARKED FUSES RELAYS. THERE ARE THREE CONNECTERS HOLDING IT. ONE ON THE PASSENGER SIDE AND TWO TOWARD THE MIDDLE. THE TWO TOWARD THE MIDDLE MUST BE TURNED ONLY 1/2 TURN AND THEN THE COVER CAN BE PULLED OFF.
