Semi truck oil leaks are among the most common problems that commercial truck owners face, causing money loss in the form of costly repairs and lost revenue due to time spent off the road for repairs. In this article, youâll learn about five of the most common types of semi truck oil leaks, along with some tips on how to fix each one.
1.) Engine Oil Leak
One of the most common semi truck oil leaks is an engine oil leak. When an engine has an oil leak, it will make a mess on the ground or trail behind you when driving down the road. The best way to find and fix an engine oil leak is by checking your oil level, making sure that it’s not low in any way. You should also check your engine area for leaks and fix any you see there.
2.) Brake Fluid Leak
Semi truck brake fluid is a non-toxic, organic liquid thatâs colorless and odorless. You might start noticing brake fluid leaks if your truck has a gurgling sound, when it seems like the brakes arenât working, or if the pedal starts feeling squishy. Brake fluid leaks are dangerous because they reduce the effectiveness of the vehicle’s brakes. To fix this type of oil leak, first consult your owner’s manual for instructions on how to find and remove the source of leakage. For example, it might be as simple as topping off your brake fluid reservoir or tightening loose connections in hoses or joints. If you still notice a leak after inspecting these areas you may need new braking system parts such as brake lines or seals for calipers.
3.) Radiator Fluid Leak
Semi truck brake fluid is a non-toxic, organic liquid thatâs colorless and odorless. You might start noticing brake fluid leaks if your truck has a gurgling sound, when it seems like the brakes arenât working, or if the pedal starts feeling squishy. Brake fluid leaks are dangerous because they reduce the effectiveness of the vehicle’s brakes.

If you still notice a leak after inspecting these areas you may need new braking system parts such as brake lines or seals for calipers.
4.) Transmission Fluid Leak
Transmission fluid leaks are usually caused by a plugged transmission filter. The plugged filter slows the flow and causes the differential, which is part of your transmission, to overheat. This type of leak will most likely be noticeable as it takes out some oil each time. Start by changing your engine oil and filter if you havenât done so in the past 5,000 miles, or if you believe itâs necessary. If that doesnât work, consult with a mechanic who specializes in transmissions. Transmission repairs are complex and may require professional help.
5.) Power Steering Fluid Leak
Semi trucks with manual transmissions are particularly at risk for power steering fluid leaks as these types of leaks often happen from worn seals or gearbox components. While it is easier to fix a leak if you catch it early, this kind of leak may not be evident for months or even years after the problem starts until there is an issue steering the truck. Often, drivers report hearing a squealing noise while the vehicle is in motion and must apply more pressure on the steering wheel to get their truck back under control. If your truck is exhibiting these symptoms and you haven’t changed your power steering fluid recently, then chances are you have a power steering fluid leak somewhere in your system.
