Maintenance Tips for Chevrolet Silverado 2500 HD Exhaust System
Although constant innovations in automotive technology have made modern exhaust systems tougher and more reliable, they still do require periodic maintenance. The same applies to the exhaust parts in your Chevrolet Silverado 2500 HD.
Regular care and maintenance of the exhaust system will help keep these components running in top condition for longer, and in case they do fail, you will be able to detect them and make repairs earlier. In this guide, we'll share some key maintenance tips you can follow for your Chevrolet Silverado 2500 HD exhaust system.
- Regular inspections are key.
There's nothing that can beat regular visual checkups in ensuring your truck's exhaust is running smoothly. Some of the notable things you should look out for include loose hangers and bolts, corrosion, cracks, dents, and other forms of damage to the exhaust components.
- Smelling exhaust inside the cabin? There could be a leak.
If you notice a noticeable smell of exhaust gas inside the truck's interior, have it inspected by a mechanic for exhaust leaks. Modern vehicle interiors are designed to effectively keep exhaust noise and gas out of a passenger cabin, so smelling exhaust inside the truck is a good indication that the seal has been broken. Keep in mind that exhaust leaks should be addressed immediately as exhaust gas contains highly toxic chemicals such as sulfur and carbon monoxide.
- Run the engine at least once every day.
Moisture tends to condense inside the exhaust system, making it among the key causes of corrosion of exhaust components. To prevent this, run the engine at least 20 to 30 minutes to allow the condensation inside the pipes to evaporate. If you will not be using your truck for an extended period of time, park it over a large plastic sheet or tarp. Doing so will prevent moisture from the floor or the ground to evaporate and condense into your car's headers, pipes, and other exhaust system components.
- Penetrating oil should be very handy.
Penetrating oil - particularly the spray-on kind - helps a great deal in keeping rust at bay as it repels moisture away from surfaces. Spray oil liberally on bolts, headers, and the areas where the tubes are welded into the header flanges; these places are often where rust tends to occur. Rusted bolts will also be easier to remove and to replace by spraying it with penetrating oil.
Key Installation Tips for the Chevrolet Silverado 2500 HD Exhaust System
Whether it is an OEM replacement or a pricey high-end cat-back exhaust, installing a new exhaust system in your Chevrolet Silverado 2500 HD should be done with utmost care and precision. This is the reason why mounting exhaust components on your vehicle is best done at an auto repair shop by a professional. But if you are confident that you have the skills and know-how as well as the required tools and equipment, it is completely possible to install a complete exhaust system in your garage.
Tip #1: Secure your truck before starting.
Aside from turning off the ignition, you should also engage the parking brake and put chocks on the rear wheels. And when lifting the car, use a pair of jack stands to support the frame. While a wooden block is sturdy enough to hold up the weight of your truck, it may snap or come loose unlike the jack stand, which is specifically designed to hold up vehicles for long periods of time.
Tip #2: Is the exhaust street-legal?
State laws are very particular about what type of exhaust components can be legally used. California, in particular, has comprehensive smog regulations that require vehicles to pass CARB standards. So before you mount that new exhaust system on your ride, check with your local Department of Transportation office on whether your vehicle can legally use your exhaust components or not.
Tip #3: Have an impact wrench and penetrating oil on hand.
Constant exposure to mud and dirt will quickly cause the bolts securing the exhaust pipes and components to become rusted shut. In such cases, you will need to spray the rusted bolts with penetrating oil and let it sit for a couple of minutes. The oil should seep through and break down the rust particles enough for the impact wrench to jar the bolts loose. Make sure to replace any severely corroded bolts as well.
Tip #4: Replace all the rubber components.
While the rubber hangers and bushings look like they are still fine, being exposed to heat and the elements have made them structurally weakened and may not support the exhaust parts over time. So invest in a new set of rubber hardware for your exhaust system as well.
