Procedures...

Test antifreeze coolant before maintenance is performed. The test strips should be used by the date on the packaging. For best results:

• Start with clean, dry hands and utensils.
• Run test in a well lit area, natural light if possible.
• Collect coolant sample from the radiator or petcock. DO NOT collect from the coolant recovery or overflow system. Coolant must be between 50° F and 130° F when tested. Room temperature is preferred.
• Remove one strip from one packet. DO NOT touch the pads on the end of the strip. DISCARD STRIP IF NITRITE TEST PAD HAS TURNED BROWN.
• Dip strip in coolant sample for one second, remove, and shake strip briskly to remove excess liquid.
• 45 SECONDS after dipping strip compare and record results in the following order: (1) Compare FREEZE POINT (end pad) to color chart card and record result. (2) Next compare MOLYBDATE (middle pad) to color chart card and record result. (3) Then compare NITRITE test to color chart card and record result. (4) Finally compare pH test to color chart card and record result.
• All four readings must be completed NO LATER THAN 75 SECONDS after dipping strip.
• It is okay to estimate a value BETWEEN color blocks, but if uncertain about the color match, pick the LOWER numbered block (ex.: if nitrite color is not F, use column E).
• Determine where the MOLYBDATE level intersects the NITRITE level on the chart. The amount of SCA units per gallon in the cooling system is given where the MOLYBDATE row intersects the NITRITE column.
• For best results follow test times carefully. Use a stopwatch or clock with a sweep second hand. Comparing the test strips to the color chart too soon or too late may result in incorrect readings and improper treatment and could result in liner pitting and engine damage.
• All readings should be recorded on the truck maintenance record for future reference.

Below 1.2 units per gallon:	Replace service filter and add 1 pint of DCA4 liquid per 4 gallons of coolant.
1.2 to 3 units per gallon:	Continue to replace service coolant filter at each oil drain interval.
Above 3 units per gallon:	Do not replace service filter until SCA level falls below 3 units per gallon. Test at every subsequent oil drain interval.
