Batteries can emit explosive gases. To reduce the possibility of personal injury, always ventilate the compartment before servicing the batteries. To reduce the possibility of arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last.
Disconnect the battery. Refer to the OEM service manual.
When using solvents, acids, or alkaline materials for cleaning, follow the manufacturer’s recommendations for use. Wear goggles and protective clothing to reduce the possibility of personal injury.
WARNING
Wear appropriate eye and face protection when using compressed air. Flying debris and dirt can cause personal injury.
NOTE: Before cleaning the inside of the air intake manifold, be sure to remove the air pressure/temperature sensor.
Clean the intake manifold gasket surface.
Clean the air intake manifold. Saturate the inside of the air intake with safety solvent.
Mineral based solvents can then be used, if the expected results with the safety solvent are not obtained.
Clean the debris with a non-abrasive brush.
Dry the air intake manifold with compressed air.
Inspect the air intake manifold for cracks and other damage.
Replace the air intake manifold if damage is found
When inspecting the air intake manifold for oil or debris from the air system malfunction, also inspect the intake ports in the cylinder head for oil and debris.
Some soot buildup inside the cylinder head is normal and will not affect engine performance.
Clean the air intake to cylinder head surface with Scotch-Brite™ 7448 abrasive pad or a gasket scraper. Do not use power tools combined with an abrasive pad to clean the gasket surfaces.
