Zack, this is to check for clogs in the catalytic converter, don't worry about it, you're going to use it for using that gauge
Selected User Reviews For Tool Aid 33600 Exhaust Back Pressure Tester
The tool I have just used is one I bought several years ago but have not used before. While the fitting that screws into the exhaust manifold is fine, the fitting on the end of the gauge hose is considerably too soft for its size. Additionally, when threading the hose and gauge into the fitting, just as you expect it to tighten up, it suddenly gives way. The vehicles I work with regularly are all different types of vehicles. Although the fasteners on my car may have been twisted off by a manufacturing defect, I do not do that. Then and now. Taking into account a tight fit may be required in a pressure test, it appears to be way too easy to torque this An open-source project was used by me When working with delicate pieces like this, it is better to use an ended wrench instead of a socket to avoid losing feel. I hope this gives you some food My test fixture may have been a great gauge, but I will never know since the section that twisted off was integral to the rest of the gauge and cannot be replaced, which makes the gauge itself an inadequate design. I opted for this tool several years ago based on all of the favorable reviews on others' sites, but that's okay. It may be possible to set this up, but I am not confident it can be done.
I could not find any problems with the product. A thorough inspection of my exhaust system revealed that I didn't have a An adapter was necessary as there was not enough room for my hose to be screwed into my rear o2 sensor bung. On my Focus SVT, my catalytic converter is located close to my CV axle. Check your exhaust for clearance issues beforehand and get an adapter if needed - it will save you headaches in the future.
The hose was not melted since I read some other reviews and I made sure not to run my engine for a long duration that will cause heat to build up at the O2 sensor holes. The gauge can be used without problems In my truck, I could see that one side of the exhaust was blocked while the other side was not.
This gauge works well (you need a dedicated exhaust back pressure gauge, because most other pressure gauges lack the sensitivity needed), it is on, and it is effective. Allows you to eliminate all guesswork associated with possible exhaust restriction issues. This book is well worth the price.
My car would not accelerate more than 15 mph, so I thought you might be interested in my story. A friend told me that Bonneville's had these problems with plugged catalytic converters. I bought this tool because he told me it would work. My diagnosis of the plugged cat took me less than 15 minutes. I bought this tool for 1/2 the price the shop wanted to sell it for.
In both cases, I have bought the device to test the back pressures before and after the catalytic converter. Although I was able to feel that the tool was well-made, I could not use it since it didn't come with the adapters I needed.
Its end that screws into the exhaust does not have a swivel on it, so you have to turn the hose and gauge to tighten it. It is only an issue in restricted areas, but this is what this tool is used for the most, so it ends up being very difficult to use. It would be great to have a right angle adapter to help you get in and out of tight spaces.
I bought this gauge in order to check exhaust back pressure. Removing the oxygen sensor and screwing the gauge and adapter into the hole for the sensor was straightforward. Upon starting the truck, the gauge indicated pressure of approximately 1 psi, yet no blockage was noted.
