Heavy-Duty Coolant Options
While the fundamental duty of engine coolants has not changed – they must transfer excess heat and offer freeze and boiling protection, plus corrosion and liner protection – modern coolants must transfer more heat than in the past, largely due to new emissions systems. When considering the energy consumed to power a heavy-duty diesel
Common Coolant Concerns – Know What You Know And Question the Rest
My column on issues surrounding the PCV system may have bordered on the mundane to some of you, but there was a method to the madness. When you stop to think about how often the PCV system is the root cause of a problem you just can’t talk about it often enough. I think of
Coolant Leaks, Head Gasket Issues on Toyota 2.2L Engines
Depending on the production date code of the engine stamped on the front of the cylinder head, two types of head gaskets are used. Use a composite-type gasket (p/n 11115-74081) if engine number is lower than 5985000. Use an MLS (multi-layer steel) gasket (p/n 11115-74120) if the engine number is 5985000 or higher. It is

EngINtel: Recycled Coolant
There isn’t one of us who has not been affected or knows someone who has been affected by the economic crisis, downturn, recession or whatever catch phrase is being used this week in an effort to try and keep us from focusing on one reality that we all are aware of – the cupboards are
Coolant Leak Leads to Unnecessary Pump Replacement
Affected Vehicles/Engines: 1993-2003 Dodge trucks and Jeeps, 3.9L V6, 5.2L & 5.9L V8. Condition: Acoolant leak from a source above the water pump or from an improperlyinstalled bypass tube on the water pump itself will cause coolant topool on top of the timing cover. This coolant then rolls across thefront of the pump and behind
Coolant Loss on 2002-2006 Toyota 2.4L, 2AZFE engines
The following information concerns the loss of coolant on some 2002-2006 Toyota 2.4L, 2AZFE engines.

I can’t seem to trace a coolant leak in a 4.3L GM. Can you help?
A. Coolant loss on 1992-1997 4.3L GM VIN R & W engines has been, at times, difficult to detect. The cause of the coolant loss has been traced to cracks that may develop in the lifter valley area of the block and allow coolant to pass into the valley of the block. This loss of
Coolant contamination of engine oil for 1996-2003 GM 3.1L or 3.4L VIN J & E engines
Engine Builders: The AERA Technical Committee offers the following information regarding coolant contamination of engine oil for 1996-2003 GM 3.1L or 3.4L VIN J & E engines due to failure of the intake manifold gasket. GM has redesigned a new intake manifold gasket (p/n 89017279) to reduce the chance of failure. The material used in
What should I tell my installers about GM coolant fill procedures with my rebuilts?
A.If you rebuild model year 2003 GM 4.8L, 5.3L or 6.0L VIN V, T and U truck engines, your customers may be unaware of new GM coolant fill procedures. The following is good information to duplicate and include with a rebuilt engine. Following this procedure will ensure that the engine coolant system has been filled
Understanding Today’s Machine Coolants
Many types of grinding and honing operations require the use of a "process fluid" for cooling and lubrication. Remanufacturing procedures such as crankshaft grinding and surface grinding generate a tremendous amount of heat and require a fluid primarily for cooling. Heat control is absolutely essential for a good finish and accurate tolerances. Use of a
