• Meeting held at Johnson City Transportation Department.

• In Attendance: Rick Crowe (WPCSD) / Mark Painter (NVCSD) / Cliff Halliday (OACSD) / Dan Hill (OACSD) / Mark Kozina (UECSD) / Gary Ingraham (SVCSD) / Bill Hawk (Windsor CSD) / Paul Schoch (Leonard Bus Sales) / Dan Henry (Fleet Pride) / Joe Long (Penray)

• Our meeting this month was sponsored by Fleet Pride and arranged by Dan Henry of Fleet Pride. Our topic of discussion was engine coolant and coolant technology and presented by Joe Long of Penray.

• Joe opened by explaining that Penray is a manufacturer and blender of coolants; marketing a full line of engine coolants and additives for the automotive and trucking industries. Joe also explained the need for an aggressive cooling system maintenance program with today’s diesel engines. This is necessary due to the increased demands placed on the cooling system by engine and vehicle manufacturers. With the increased use of EGR’s (exhaust gas recirculation devices) to help meet federal emission standards, manufacturers are dumping anywhere from 20-40% exhaust gases back through the engine for combustion. This increases engine temperatures and cooling systems must now be able to meet this demand, coupled with the added task of transmission cooling, and nestled behind engine oil coolers, A.C. condensers, etc. It’s easy to see why cooling system maintenance can no longer remain an annual event and must be monitored more closely.

• Joe recommends regular testing of the radiator cap to ensure that it will hold its rated pressure, as it is this pressure that raises the boiling point of the coolant. Ethylene glycol lowers the freeze point and the particular additive package maintains the proper ph value, as well as provides protection against cavitation, etc. He also recommends a simple 4 test procedure for checking your coolant.
- color
- clarity
- freeze protection
- chemical protection
 First you must determine the type of antifreeze - green, purple, blue, pink, gold, or red.
 Second is clarity. Coolant must not be muddy, brown, cloudy, or murky.
 Third is freeze point. Is your coolant protecting you at least to -34 degrees? This is a 50/50 mix and is best checked with a refractometer.
 Forth is chemical protection. This tests the coolants additive package as well as the ph value (best done with coolant test strips). These are available from Fleet Pride and many other out lets.

• A lengthy discussion followed with many questions and concerns being addressed. Joe Long of Penray will answer all questions and provide technical assistance and guidance to all who ask. He can be reached at jlong@penray.com .

• This brought our very interesting and informative meeting to a close at approximately 11:45. Our next meeting will be February 9, 2010 at J.C. bus garage. Hope to see you there.
