Removing Oil Pan On '95 Bronco: Step-By-Step Guide

Removing the oil pan from a 1995 Bronco can be a challenging task, but it is possible to do it without pulling the engine. Here are the steps you need to follow:

1. Drain the cooling system and remove the bolts attaching the fan shroud to the radiator.

2. Remove the upper intake manifold and throttle body.

3. Disconnect the oil cooler line at the left side of the radiator, if equipped with an automatic transmission.

4. Remove the exhaust system.

5. Raise the engine and place wood blocks under the engine supports.

6. Drain the crankcase.

7. Support the transmission with a floor jack and remove the transmission crossmember.

8. Remove the oil pan attaching bolts and lower the oil pan onto the crossmember.

9. Clean the oil pan and gasket surfaces. Inspect the gasket sealing surface for any damage or distortion.

10. Position a new oil pan gasket and seal to the cylinder block.

11. Reinstall the oil pump pickup tube and screen, and bolt them securely.

12. Place the oil pan back on the crossmember and tighten the bolts.

13. Reinstall the transmission crossmember and raise the engine, removing the blocks under the engine supports.

14. Bolt the engine to the supports and reinstall the exhaust system.

15. Reconnect the oil cooler line, if applicable.

16. Reinstall the upper intake manifold, throttle body, and fan shroud.

17. Finally, fill and bleed the cooling system.

It is important to note that some people have managed to replace the oil pan gasket without completely dropping the pan. This involves snaking the old gasket out and sliding the new one into place. However, it is generally recommended to drop the pan for a more thorough job. Additionally, some have found it necessary to remove the oil pump before accessing the pan, which can add complexity to the process.

Jack up the engine and place wood blocks under the engine supports

Jacking up the engine of a 1995 Bronco is a delicate task. The oil pan is made of sheet metal and is not designed to bear the load of the engine. However, with a large enough wooden block, the load can be distributed more evenly, reducing the risk of damage to the pan.

To begin, place a floor jack under the Bronco, towards the front of the transmission. A wooden block should be placed on the jack, and then gently raised until it makes contact with the oil pan. The jack should be raised until the engine is lifted slightly, and wooden blocks should be inserted between the engine and the engine supports to maintain this clearance.

It is important to note that the engine should not be lifted too far, and care should be taken to avoid lifting the entire front end of the vehicle. The jack should only raise the engine enough to insert the wooden blocks, and no more. Once the blocks are in place, the jack can be lowered, and the engine weight will rest on the blocks.

This process will provide the necessary clearance to remove the oil pan and access the oil pump and pickup tube for maintenance or replacement. It is critical to ensure that the engine is securely supported by the blocks before lowering the jack and proceeding with any further work.

Drain the crankcase

To drain the crankcase of a 1995 Bronco, follow these steps:

• Drain the cooling system. Be cautious when draining the coolant as cats and dogs are attracted by ethylene glycol antifreeze and it can prove fatal if ingested. Always drain the coolant into a sealable container.
• Remove the bolts attaching the fan shroud to the radiator and position the shroud over the fan.
• Remove the upper intake manifold and throttle body.
• Remove the nuts and lockwashers attaching the engine support insulators to the chassis bracket.
• If equipped with an automatic transmission, disconnect the oil cooler line at the left side of the radiator.
• Remove the exhaust system.
• Raise the engine and place wood blocks under the engine supports.
• Wear protective gloves and clothing to minimise exposure to used engine oil.

Remove the oil pan attaching bolts

To remove the oil pan attaching bolts, first, drain the cooling system. Remove the bolts attaching the fan shroud to the radiator and position the shroud over the fan. Then, remove the upper intake manifold and throttle body. Next, remove the nuts and lock washers attaching the engine support insulators to the chassis bracket. If equipped with an automatic transmission, disconnect the oil cooler line at the left side of the radiator.

Remove the exhaust system. Raise the engine and place wood blocks under the engine supports. Drain the crankcase. Support the transmission with a floor jack and remove the transmission crossmember. Finally, you can remove the oil pan attaching bolts.

Remove the oil pump pickup tube

To remove the oil pump pickup tube on a 1995 Bronco, follow these steps:

First, ensure you have the necessary tools and equipment. You will need a floor jack, wooden blocks, wrenches, and sockets. It is also recommended to have an engine hoist or cherry picker for additional support.

Begin by draining the cooling system and removing the bolts attaching the fan shroud to the radiator. Position the shroud over the fan. Then, remove the upper intake manifold and throttle body. Disconnect the throttle linkage at the throttle ball and transmission linkage from the throttle body.

Next, remove the nuts and lockwashers attaching the engine support insulators to the chassis bracket. If your Bronco is equipped with an automatic transmission, disconnect the oil cooler line at the left side of the radiator.

Remove the exhaust system and raise the engine. Place wooden blocks under the engine supports. Drain the crankcase to prevent oil spillage.

Now, you can begin to remove the oil pump pickup tube. Support the transmission with a floor jack and remove the transmission crossmember. This will provide access to the oil pan and pump.

Remove the oil pan attaching bolts and lower the oil pan onto the crossmember. You may need to use a wrench to loosen any stubborn bolts. With the oil pan lowered, you will have access to the oil pump pickup tube.

Remove the two bolts attaching the oil pump pickup tube to the oil pump. Then, remove the nut attaching the tube to the No. 3 main bearing cap stud. With these fasteners removed, you can carefully lower the pickup tube and screen into the oil pan.

At this point, you have successfully removed the oil pump pickup tube. You can now clean the oil pan and gasket surfaces or proceed with other maintenance tasks as needed.

Please note that this process may vary slightly depending on the specific model and configuration of your 1995 Bronco. Always refer to a qualified mechanic or a Bronco-specific repair manual for detailed instructions.

Clean the oil pan, inlet tube and gasket surfaces

To clean the oil pan, inlet tube and gasket surfaces, you will need to first drain the crankcase. You can then remove the oil pan from the vehicle. Use plastic or composite tools to scrape away the old gasket from the oil pan, taking care not to scratch the metal. You can also use a wire brush to clean the surface. Apply a detergent that breaks down oil, such as Simple Green, and scrub with a shop cloth or paper towel. Repeat this process for the inlet tube and gasket surfaces, taking care to clean all oil residue.
