Does it matter what coolant I use?

Well, you use the coolant that is specified in your owner’s manual. If you just need to top it up, the recommendation is still the same, however it is unlikely to cause any serious problems if you add a litre of a different type of coolant, as long as you follow the manufacturer’s maintenance schedule.

What is recommended for testing coolant?

Look for a reading of -34° F on the freeze point side and a reading of 265° F on the boiling point side of the tester. The see-through body of a hydrometer is handy for inspecting the condition of the coolant, looking for rust and contaminants. Test strips also test the alkalinity of the engine’s coolant.

What is added to coolant to prevent cavitation?

The nitrite or molybdate will form a thin protective oxide film on the coolant side of the liner wall. This oxide film, which is formed by reaction of the nitrite or molybdate with the liner wall, acts as a protective barrier to prevent corrosion and cavitation (pitting) from occurring.

How many gallons of antifreeze does a 6.7 Cummins take?

Your vehicle requires 4 gallons of Full Strength Liquid Chill® Synthetic Engine Coolant or 8 gallons of 50/50 Premixed Liquid Chill® Synthetic Engine Coolant.

What causes cavitation in diesel engines?

This erosion may be caused by excessive harmonic vibrations in the engine and possibly by or in conjunction with loose fitting cylinder liners. Both cause the formation and implosion of vapor bubbles within the coolant, which attack and erode the cylinder liner surface.

What is wet liner cavitation caused by?

Liner pitting, or cavitation-erosion, occurs along the thrust angle of the piston. The liner sits inside the block, and ‘rings’ like a bell every time that the cylinder fires. This ringing causes intense pressure changes at the cylinder wall, resulting in liner cavitation.

Is there a way to clear a Cummins fault code?

Depending on the powertrain control module (PCM) software or “flash”, the above procedure might not work. If that’s the case, then an Onboard Diagnostics scanner (OBD-II) can be used to clear the fault codes. This will clear any pending or currently active codes.
