Removing an oil pan

PAN-ENGINE OIL

REMOVAL

Disconnect the negative battery cable.

Install engine support fixture (1) special tool # 8534. Do not raise engine at this time.
Remove both left and right side engine mount through bolts.

Remove the structural dust cover.
Drain engine oil.

CAUTION: Only raise the engine enough to provide clearance for oil pan removal. Check for proper clearance at fan shroud to fan and cowl to intake manifold.

Raise engine using special tool (1) # 8534 to provide clearance to remove oil pan.

NOTE: On 4WD vehicles, the front axle must be lowered, to provide clearance for oil pan removal. It is not necessary to remove the front axle from the vehicle, or remove the axle shafts.

For 4WD Vehicles Remove the pinion bracket.
For 4WD Vehicles Disconnect the front driveshaft at the front axle.
For 4WD Vehicles Remove the front axle mounting bolts.
For 4WD Vehicles Lower axle using suitable jack enough to provide clearance to remove oil pan.

NOTE: Do not pry on oil pan or oil pan gasket. Gasket is integral to engine windage tray and does not come out with oil pan.

Remove the oil pan mounting bolts and oil pan.
Unbolt oil pump pickup tube and remove tube.
Inspect the integral windage tray and gasket and replace as needed.

INSTALLATION

Clean the oil pan gasket mating surface of the bed plate and oil pan.
Position the oil pan gasket and pickup tube with new o-ring. Install the mounting bolt and nuts. Tighten bolt and nuts to 28 Nm (20 ft. Lbs.).

Position the oil pan and install the mounting bolts. Tighten the mounting bolts to 15 Nm (11 ft. Lbs.) In the sequence shown.

Lower the engine into mounts using special tool (1) # 8534.
Install both the left and right side engine mount through bolts. Tighten the bolts to 68 Nm (50 ft. Lbs.).
Remove special tool # 8534.

Install structural dust cover.

NOTE: On 4WD vehicles, the front axle must be lowered, to provide clearance for oil pan removal. It is not necessary to remove the front axle from the vehicle, or remove the axle shafts.

For 4WD Vehicles Raise axle using suitable jack.
For 4WD Vehicles Install the front axle mounting bolts.
For 4WD Vehicles Install the pinion bracket.
For 4WD Vehicles Install the front driveshaft to the front axle.
Fill engine oil.
Reconnect the negative battery cable.
Start engine and check for leaks.

Good morning.

Below is the procedure. You will need an engine lift to lift the engine enough to remove the oil pan.

Hello,

Here are the instructions from the manual.

Disconnect negative battery cable. Remove oil dipstick and distributor cap. Raise and support vehicle. Drain engine oil.

Remove exhaust pipe.

Remove side engine mount bolts.
Slightly raise engine.

When engine is at adequate height, install bolts in side engine mount-to-frame bracket holes to support engine

Lower engine, and allow it to rest on bolts installed in side engine mounts.

Remove oil pan bolts, oil pan and gaskets.

Please let us know what happens.

Cheers, Ken

It isn't hard to do. There are several bolts that hold it on. The worst part is when removing it, the fluid will fly everywhere if you're not careful. Just purchase a new filter and gasket at the local parts store so you can replace the filter too (easy to do). WHen you remove the pan, loosten all bolts except 3 that are side by side. After the rest are out, begin loostenrtg the three slowly so the pan starts to open on the opposite end. That way, the fluid will pour out of one side rather than everywhere. Once it is drained, remove and clean the pan, remove all old gasket from the pan and trans, replace the filter that will be right there, and reverse the sequence. Make sure not to over tighten the bolts or you will end up with a new leak.

As far as the number of quarts of ATF, first make sure to get the correct type (I BELIEVE it is ATF+4) it will say it on the dipstick. Start with around 3.5 to 4 quarts. Start the engine, run the shifter through all gears a few times and allow the vehicle to warm up. Then check the level and fill it as necessary. I think 4 is going to do it, but it may be a little less or more.

If you have other questions, let me know.

Welcome to 2CarPros.

You shouldn't have to remove the pump. Here are the directions specific to removal on your vehicle. Also, have you removed the distributor? It will hit the firewall/cowl and stop the engine from going high enough. Again, here are the directions from Alldata. Take a look through them.

PROCEDURES
1. Disconnect battery ground cable, then remove oil dipstick.
2. Disconnect distributor cap and set aside away from cowl, then raise and support vehicle.
3. Drain engine oil, then remove exhaust crossover pipe.
4. Loosen side engine mount bolts, then using suitable jack and wood block positioned at oil pan, raise engine slightly and remove side engine mount bolts.
5. When engine is high enough, place bolts similar to engine mount bolts in mount attaching points on frame brackets. Lower engine so mount bottoms rest on installed bolts.
6. Remove oil pan and gasket.
7. Reverse procedure to install. Apply in corner of cap and block. Tighten attaching bolts to specifications.

Let me know if this helps.
