Strainers:As a general rule of thumb, strainers should be of adequate capacity to create no more than 1.5-2.0 psi (10-14 kPa) of pressure drop under clean strainer conditions at maximum flow.Typical Friction Losses of Water in Pipe - (Old Pipe) (Nominal Pipe Diameter)

Temperature Regulators
New Temperature Regulators - 1330, 1355; 3606 (8RB), 3608 (6MC), 3612 (9RC), 3616 (1PD) Industrial Engines
The 3600 Family of Engines has three sets of temperature regulators. The regulators are the jacket water (JW) inlet control, the oil cooler and aftercooler (O/C and A/C) inlet control, and the oil cooler oil temperature control. The chart identifies the new and former regulators. The recommended service hours of temperature regulators is every 6000 service meter hours or annually, whichever occurs first.Diagnostic Tooling
Self-Sealing Probe Adapters:Coolant Expansion Rates
As a rule of thumb, expansion tanks should have a capacity of 16% of the total system coolant volume for expansion plus reserve.Densities of Liquids [at 60°F (16°C)]
Supplemental Coolant Additive (Conditioner or Inhibitor)
Caterpillar recommends using antifreeze in the coolant mixture to get maximum life from cooling system components. 30% is minimum recommendation.
