Power Steering Stop Leak (Complete Review)

By: @Hani


In this article, I will be telling you guys about my experience with my Power Steering Leak. I had a leak in my power steering rack. I'll guide you through the diagnoses of a leak and then tell you about my experience with the stop leak.

Diagnoses:

You can easily tell if you have a leak by listening to a whine that comes from the engine bay. Check the power steering reservoir to see if the fluid is below the recommended level. If you established that you have a power steering leak, start looking at the tubes coming from the reservoir and follow them to the engine.

Also check the tubes going in and out of the power steering rack. That is where the system is connected to the power steering pump. If you find a leak in the tubes, it is cheaper to just change the tube than to buy a power steering stop leak.

If you don't find a leak in the tubes, check under the car and look at the power steering rack. If you find fluid on the car parts which are underneath the rack, it means that your rack is leaking. You can also check the boots to check if there is any fluid in them.

You can take a look at the following picture for reference.

If you don't find the leak, then have a mechanic take a quick look at your car. They are skilled and should be able to find the source of the leak quickly.

A good warning is to NOT let the car run on low levels of fluid since that can damage your power steering pump which is expensive to replace.

 

Stop Leak Review:

I used Lucas Oil Power Steering Stop Leak on my car which is a 2007 Mitsubishi Pajero just for your reference. I was not paid by Lucas Oil to review the product. I bought it with my own money so I am going to give you my honest review of the product.

To start, the instructions for usage of the stop leak recommend that you replace the fluid that's currently in your system with the stop leak fluid.

You can do that by going to the low pressure tube that is connected to the power steering rack and disconnect it and let the oil drain. If you do not wish to do this step, you can use a syringe and suck out the oil from the reservoir, but that is not what Lucas Oil recommend.

I replaced the oil in my system to the Lucas Oil Power Steering Stop Leak. My system required about 2 bottles to be completely full. I let the engine run and checked the reservoir to see if there was any air trapped in the system and that the oil level did not drop below the level recommended on the reservoir. 

Before using the Lucas Stop Leak, I had to top up my power steering fluid every 2 to 3 days. After using it, I noticed a great decrease in the fluid leak. I thought that the leak had stopped completely. However, after a month, the fluid level dropped a little. This means the leak was mostly mended by the Lucas Stop Leak.

I think the leak in my power steering was too big for the Lucas Stop Leak to be completely effective. I eventually changed my power steering rack about two months after using the stop leak. This leads me to my recommendation.

Recommendation:

The product is very effective on small leaks. It can also greatly slow down major leaks if you do not have the money to change the part that is causing the leak.

It can help your system last for a couple of months extra with just small top-ups from time to time until you are capable of changing the cause of the leak. Therefore, if you have a small leak, Lucas stop leak will be the choice for you.
