How do u take off the oil pan on a 1999 awd bravada 4.3


Hello skullz, this is a fairly big task but it can be done in your driveway. Take your time, keep track of all your parts you remove. Use masking tape and a sharpie to label stuff if you feel like it will make easier to reinstall....These steps are for a 99 blazer 4x4 with an aluminum pan. You wont need to do some of the shift linkage removal due to the AWD and electronics the Olds has.

Disconnect battery and remove battery tray. Disconnect shift cable at actuator. Raise and support vehicle.

Remove underbody shield from steering linkage and engine oil pan. Drain crankcase. Remove starter motor.

Remove oil cooler pipes and both front wheels. Disconnect electrical connector and remove wiring harness bracket at shift cable housing.

Remove 3 shift cable housing bolts and disconnect shift cable from differential carrier. Remove both front drive axles. Remove differential housing.

Remove 10 oil pan bolts, 2 nuts at crankshaft rear oil seal and remove 2 transmission to oil pan bolts....Remove oil pan from vehicle....When you reinstall & tighten the oil pan bolts, start in the middle of the pan and go back to the bellhousing, directly across from each bolt---left, right, left right...then, from the middle towards the front of engine, right, left, right left...Torque to 18 ft/lbs

Good luck... if you tackle this job its a fun one....

My dealer tells me my oil pan threads are wore and i need a new pan is this possible


the story you are getting from the dealership sounds very strange. Contrary to what the dealer states the oil pan threads do not wear out over time or the quantity of oil changes. The oil pan threads will strip (be damaged) if the oil plug is tightened too much (too much torque is applied) when installing the plug.

On all cars and Mitsubushi's I have seen the oil pan plug is sealed from leaking oil with a metal or composite washer. The washer is installed on the plug and seals between the plug head and pan. The treads of the plug do not seal the pan as the washer serves this purpose. In most cases it is recommended this washer be replaced (a dollar or less) with every oil change but most people don’t. Have never seen a car that used only the treads to do the sealing.

It is possible someone has over tightened the plug at least once or many times leading the to the threads being stripped. If all your oil changes were at a dealer, then this damage was done by mechanics at the dealer. The other question is if the same dealer did your changes over a year (how many changes have been done?), why didn’t they bring this up before? Oil pan plugs do not just go bad, the pan threads fail because the plug is over tightened

but yes this is definetly possible in both the sense of the oil dran plug or the bolts that connect the oil pan to the engine block. Now if you mean the bolts that connect the oil pan to the engine block its only possible if the oil pan has been removed and someone put the bolt back in crossthreaded it or over tightened them. It couldnt so much happen from normal vibration, it would be a human error problem. and as for the drain plug that was covered above.
If you need further explanation on this problem please feel free to follow up with a comment and i will assist you from there. If this assisted you please feel free to rate it. Thanks, Midwest-tek
