7.3 Powerstroke Oil Pan, Cooler, Filter, and Gasket

If you have a 7.3 Powerstroke, you should know all about the oil pan, cooler, oil filter, gasket, and transmission fluid capacity besides picking the right oil for your 7.3 Powerstroke.

Here to make your task easy and simple, today we will bring all these facts in front of you so that you can keep your Powerstroke engine healthy and safe. 

So, let’s start… 

7.3 Powerstroke Oil Cooler

The oil cooler in 7.3 Powerstroke needs proper maintenance and care. To get longer support for the engine, we have to check the cooler’s regular operation. If the oil is leaking, it is in a bad shape. 

If the oil is mixed with coolant, then it may lead to a cracked cylinder head or blown head gaskets. There is a serious possibility of oil entering the cooling system. It will make the system damaged. 

7.3 Powerstroke Oil Pan

This part of the engine leaks very often and hampers the engine oil operation. To keep the pan safe for years, you have to check its status regularly. If there is any crack or the O-ring leaks then, we need to use sealant to fix the gaps. 

If you fail to fill up the gaps, the engine oil will leak and spread in the engine. When you see the pan is rusted, then it will be the right decision to replace the oil pan

7.3 Powerstroke Oil Pan Gasket

Gasket might not be considered an important part at all. But with Oil Pan, it works as a shield. Cleaning and keeping the gasket will keep the engine oil working properly. If the oil pan is fine and the gasket is old, you will face oil leakage.

So, if you see the gasket is old, just replace it. 

It is not a costly accessory, so you can get it done with a few dollars. When is it necessary to replace? If it does not fit, or it is old. Replacement of gasket is the right method. 

7.3 Powerstroke Oil Filter

The Powerstroke has a diesel FL-1995 type engine which needs a perfect type of oil filter. The size is 4.25 inch and it comes with a filter bypass relief valve & Anti-drain-back valves.

It is able to filter the smallest particles like 20 microns. You know that the oil filter has a crucial role in engine operation. It keeps the engine steady and engine oil working properly to keep the engine cool. 

If you see that the engine is consuming more oil and making noise, you should look for the oil filter condition. If you see it is not working properly, just replace it. 

7.3 Powerstroke Oil Filter Number

Isn’t it confusing to see all the oil filters look the same? The outlook of them is the same, but from inside the technical features are different. For the diesel engine, you can use S&B KF-1059 filters.

The part number is WF-1040. If you want to buy it online just search with LF3974 and get the right product. 

7.3 Powerstroke Transmission Fluid Capacity

We have used different amounts of fluid for transmission. It might be a little confusing, but sharing the information with you here. All over the year, you will need up to 15 quarts of engine oil.

For the auto transmission engine, you need 15.9 quarts, 16.4 quarts, and 17.1-17.7 quarts. Similarly, for a manual transmission engine, you will need 3.4 quarts and 5.8 quarts. 


What is the oil capacity of a 7.3 diesel?

It can accommodate up to 8.0-quart engine oil. You can use more, after a specific time span. So, it will not be a problem to add oil when needed, just keep track of how much you are using and if that is too much or not. 

What oil is recommended for Powerstroke engines?

Ford recommends using 10W-30 oils. If you are a heavy and offroad user, then use a 15W-40 oil for the engine. By using the right type of oil, you can get a smoother ride.

How often should you change oil in a 7.3 PowerStroke?

You have to change the oil after every 5,000 miles. Similarly, you have to change the oil filter every 15,000 miles. By changing oil and oil filters, your engine will experience smooth operation. 

What brand oil does Ford recommend?

Officially there are no brands that are recommended by Ford. But when they service your truck, they use Motorcraft and most of their customers also love to use it.
