Sec.  1065.122  Engine cooling and lubrication.

    (a) Engine cooling. Cool the engine during testing so its intake-
air, oil, coolant, block, and head temperatures are within their 
expected ranges for normal operation. You may use laboratory auxiliary 
coolers and fans.
    (1) If you use laboratory auxiliary fans you must account for work 
input to the fan(s) according to Sec.  1065.110.
    (2) See Sec.  1065.125 for more information related to intake-air 
cooling.
    (3) See Sec.  1065.127 for more information related to exhaust gas 
recirculation cooling.
    (4) Measure temperatures at the manufacturer-specified locations. If 
the manufacturer does not specify temperature measurement locations, 
then use good engineering judgment to monitor intake-air, oil, coolant, 
block, and head temperatures to ensure that they are in their expected 
ranges for normal operation.
    (b) Forced cooldown. You may install a forced cooldown system for an 
engine and an exhaust aftertreatment device according to Sec.  
1065.530(a)(1).
    (c) Lubricating oil. Use lubricating oils specified in Sec.  
1065.740.
    (d) Coolant. For liquid-cooled engines, use coolant as specified in 
Sec.  1065.745.
