IVD Intake Valve Cleaner

It’s a fact that deposits form in every fuel system, but the amount and how quickly they form depend on the quality of fuel and oil used, on personal driving styles and on engine type.

GDI engines are particularly prone to rapid build-up of fuel deposits because they’re never cooled or washed with fuel.  Deposits can form in as few as 5,000 to 10,000 miles, restricting proper airflow and increasing engine operating temperatures.  These harmful fuel deposits cause a variety of problems, preventing your vehicle from operating properly.  Unlike common fuel additives that are diluted into fuel before reaching critical fuel system components, GDI IVD Intake Valve Cleaner from CRC Industries is sprayed directly into the air intake system.  This powerful cleaner hits the back of the intake valves at 150 times the concentration of premium fuel additives.  Intake Valve Cleaner is proven to remove up to 23% of carbon build-up in the first hour of use.  It works in all gas-powered engines, not just GDI.  When using Intake Valve Cleaner from CRC, time consuming and costly engine teardown is no longer required to clean intake valves, especially on GDI engines where previously, engine teardown was the only option.

Apply GDI IVD Intake Valve Cleaner with the engine running and at operating temperature.  The unique PermaStraw actuator locks into place, preventing the straw from being drawn into the air intake.  Remove the air filter cover and locate the MAF sensor between the air box and throttle body.  Have someone rev the engine to about 2000 rpms and, engage or lift the PermaStraw Dual-Action Spray System and insert past the MAF sensor.  It’s very important that you do not spray the product in front of the MAF sensor. This could cause the system to throw a code.

You may need to disassemble the air intake to spray the product past the MAF sensor. Again, with the engine running at 2000 rpms, spray the product into the air intake behind the MAF sensor, spraying continuously in 30-second intervals until the can is empty.  If necessary, accelerate slightly during the application to avoid stalling but don’t exceed 3500 rpms.  When the can is empty, accelerate the engine 2 to 3 times but no higher than 3500 rpms.  Run at idle for one minute and, then turn the engine off.

After application, reassemble the air intake system and let the engine “heat-soak” for an hour.  Restart the engine and drive at highway speeds for about 10 minutes.  Using CRC Intake Valve Cleaner will increase power and torque.  It stabilizes rough idle and solves rough starting problems.  It is highly effective for all gasoline engines and regular use will reduce emissions and improve fuel economy.

QD DiElectric Grease

Accumulations of dirt, grease and contaminants in your vehicle’s electrical system can eventually lead to contact failure and malfunction.  After cleaning contacts and connections with QD Electronic Cleaner, follow with technician grade Di-Electric Grease from CRC.

CRC Di-Electric Grease seals, protects, lubricates, insulates and prevents water from getting into electrical connections and contacts, helping prevent corrosion, which can damage wiring and cause malfunctions. Corrosion on lamp connectors and wiring causes bulbs to burn hotter, shortening their life.

To apply Di-Electric Grease the vehicle and power supply should be off.  Be sure the area has first been cleaned with CRC QD Electronic Cleaner.  Allow any hot surfaces to cool before an application.   Just squeeze the trigger to dispense Di-Electric Grease, and apply an even coat to electrical connections and contacts.  Use it on circuit breakers, ignition coil connectors, the HEI distributor, plastic or rubber parts, fasteners and o-rings.  CRC Di-Electric Grease is great for spark plug boots where the rubber meets the porcelain to keep them from fusing together and, it helps prevent arcing between the boot and the metal part of the plug.  It’s also perfect for your trailer lighting and the trailer harness, bulbs and bulb connectors.  There’s no overheating of connections, which extends lamp life.

CRC Di-Electric Grease prevents bonding so that components can be easily removed.  CRC Di-Electric Grease can also be used on many outdoor applications around the house such as outdoor power receptacles and lamps, tools and power equipment.  It improves electrical performance and provides critical protection for electronic components exposed to rain, fog, salt spray and temperature extremes.

MAF Sensor Cleaner

Most fuel-injected vehicles are equipped with a mass air flow sensor, or “MAF” sensor to measure the amount and density of air entering the engine.  This is information the computer uses to determine how much fuel to inject into the engine for combustion as air enters the cylinders. Ignition timing is also affected.  The MAF sensor wire gets dirty with accumulated debris, oil, air filter fibers, dust and pollen.  This can cause inaccurate readings and negatively affect the air to fuel ratio.

Signs of a dirty MAF sensor could be a check engine light.  You may experience a loss of power, stalling, rough idle.  Your engine may also be running rich and producing excess emissions.  The original Mass Air Flow Sensor Cleaner from CRC Industries is a unique precision cleaner specifically developed to clean sensitive components in MAF sensors without damaging or degrading plastic or painted surfaces.

Use CRC Mass Air Flow Sensor Cleaner with the engine off. Always wear gloves and eye protection, and insert the straw into the nozzle before an application.  Remove the air filter to gain access to the MAF sensor located between the air box and the throttle body.  It is recommended that you remove the sensor for best cleaning, but it’s not absolutely necessary.  Place a towel under the MAF to catch any run-off.  Using the straw attachment, apply 10 to 15 short bursts of CRC Mass Air Flow Sensor Cleaner to the hotwire or the hot plate.  Be careful not to let the straw, or anything else come in contact with hotwire. Keep the end of the straw 4 to 5 inches from the hotwire.  Be sure to spray all sides of the MAF sensor and clean all wires and connectors.  Reassemble the MAF and allow to dry thoroughly before restarting the engine.

Often, technicians will try to use throttle body, carburetor, or brake parts cleaners to clean sensitive MAF sensor components.  However, these aggressive cleaners can be damaging to plastic, which most MAF sensors are housed in today.  If the plastic degrades or warps, the MAF hotwire can shift and malfunction, resulting in expensive repairs.  Use only the original Mass Air Flow Sensor Cleaner from CRC Industries to safely clean the delicate components of the sensor.  Regular use will restore horsepower, reduce rough idle, decrease hesitation and pinging and improve gas mileage.
