To unclog a catalytic converter, get onto a highway, and drive at high speed for a couple of miles, coming to a stop and starting again several times. Repeat two or three times, giving the converter a chance to expel debris.Know More
Take your car onto a highway, and drive it at the speed limit for 1 to 2 miles. Check your mirrors to make sure that a sudden deceleration is safe, and slow the car down quickly. Move over to the shoulder to complete this if necessary. Accelerate back to highway speed, repeating the process several times during the 2 miles. Estimate whether acceleration has improved; this is the best sign that you see while driving that the clog is gone.
Resume driving on the highway if the clog is still present. Check your mirrors and the surrounding lanes to make sure that driving somewhat above the speed limit is safe, and then drive up to a mile at that speed. Check your mirrors again, then slow to about half your speed and then accelerate again, going another mile.
Measure your mileage the next two or three times you fill up your car with gasoline. Consider the performance of your car during acceleration, and use these two factors to determine whether replacing the catalytic converter is necessary.
Platinum content in catalytic converters can differ significantly depending on the year the catalytic converter was fabricated and the type of vehicle. Small cars usually average 1 to 2 grams per car, while larger trucks can have as much as 12 to 15 grams.Full Answer >
To clean a catalytic converter, pour catalytic converter cleaner into the gas tank, drive until the tank is close to empty, refill the tank, and re-calibrate the vehicle's on-board computer. This helps to maintain components while reducing pollution emissions and eliminating foul smells.Full Answer >
Take off the oxygen sensor, unbolt the catalytic converter and slide it along the exhaust pipe until it falls off. In some vehicles, the converter is welded to the underside. In this case, put the car up on a lift before using a rotary saw to take the converter off.Full Answer >
Mr. Gasket Cataclean is a solution that serves as a cleaner for the fuel and exhaust system that cleans the catalytic converter by reducing carbon build-up. This formula also cleans the fuel injectors, oxygen sensors and cylinder heads. It is safe for all engines and does not change fuel composition.Full Answer >
