An uptick in catalytic converter thefts has a lot of street parkers concerned. Here’s how to prevent a catalytic converter theft from happening in the first place.
Depending on the make and model of a car, certain catalytic converters, like the ones under a Toyota Prius, can fetch over $1,000 on the used market. And, with a few turns of a wrench, it’s no wonder thieves are getting bold, stealing catalytic converters in the middle of the day, effectively making a grand in less than a minute. Here are a few DIY ways you can probably use to prevent catalytic converter theft.
Determine if your catalytic converter is under your car or in front of your engine under your hood.
There’s a reason catalytic converter thefts happen mostly on trucks, most truck catalytic converters run directly underneath the chassis where it’s easily accessible. Some cars, like the Toyota Prius Hybrid, also have their catalytic converters here.
But, some cars, vans, suvs, and trucks have their catalytic converters directly in front of the engine, part of the exhaust manifold. In order to take those out, you’d have to pop the hood to reach them. These “under the hood” cats are harder to steal so, for the most part, you don’t have to worry about those being stolen.
First, confirm the catalytic converter’s location. A quick google search like, “1999 Honda Civic Catalytic converter location” should do the trick.
Be sure to indicate your car’s trim level, too. Some cars, like the 1996-2000 Honda Civic, have catalytic converters in front of the engine or underneath the car depending on your model. DX trim level Civics have their cats in front while LX EX Civics have theirs underneath the car.
Secure the cat with a DIY rebar cage welded on
If you’re a bit handy, have the tools to bend, cut, and weld rebar, you can effectively make your own DIY rebar cage to surround your catalytic converter.
The news is full of a handful of individuals who did just that. I recommend looking up “Rebar Cage Catalytic Converter.” You’ll come across some great ideas to work on your own catalytic converter.
These Toyota Tacoma owners linked here came up with some DIY Rebar cages of their own to, at best, deter thieves from their catalytic converters.
The Sacramento Bee reports that a one pickup truck owner deterred a would-be catalytic converter theft from happening thanks to a welded on a piece of rebar on their catalytic converter.
If you’re not really handy but still want a cage of your own, go ahead and call your local dealership or surrounding muffler shops. You’re probably not the first person to call asking for a rebar cage around their catalytic converter and a muffler shop or the dealership can install one on for you for a small fee.
Be advised, if you plan on using any other metal besides rebar steel, know that different metals react differently to heat. Catalytic converters can reach temperatures of up to 1,600 degrees F so plan your metal choice accordingly.
Etch your VIN and/or spray paint your cat with high-temp paint
Some dealerships and exhaust shops will, for a small fee, etch your VIN (Vehicle Identification Number) and other identifying information on catalytic converters so when a would-be thief sees this, they may just walk away from your car.
Google around your area and maybe ring up your local police department about Catalytic Converter etching. Some police departments, like this Roseville community in Sacramento, do it for free certain times of the year.
You can also etch on your VIN and license plate number, two pieces of information that should raise alarms to scrap metal yards that this cat converter is stolen.
Also, spray painting your catalytic converter a bright red or blue with some high-temperature BBQ spray paint might deter some thieves, turned off by having to sell something spray-painted to a scrap yard.
Install a dashcam
For as little as $50, in addition to the above theft prevention methods, you can get yourself a dashcam that records upon motion detection, whether it’s movement in front of the camera or physically rocking your car.
You’ll want to choose a dashcam with a standby mode, sometimes referred to as a parking mode, that records when motion is detected.
Although this won’t protect your catalytic converter per say, you can catch the license plate of the offending party and their faces.
It’s generally a good idea to have a dashcam now anyway.
Special catalytic converter cages
Not particularly DIY but it’s worth mentioning there are special catalytic converter cages that you can buy, the most popular ones called “Cat Clamp” and “Cat Strap”, that secures your catalytic converter. These options do cost several hundred dollars.
Like the above-mentioned methods, a determined thief with a cordless Sawzall can still defeat these special cages despite what they might advertise.
To sum up, deterring thieves is the name of the game. No prevention method is 100 percent foolproof but they’re better than doing nothing.
