Q&A
-
-
-
-
-
-
Q1: Is there a difference between an "Aftercooler" and a "Charge Air Cooler"?
-
A: In the context of the 281-3587, these terms are used interchangeably. Both refer to the heat exchanger that sits between the turbocharger and the engine intake manifold.
Q2: What happens if my 281-3587 aftercooler has a pinhole leak?
-
A: You will experience a "boost leak." This leads to a noticeable loss of power, excessive black smoke from the exhaust, and higher exhaust gas temperatures (EGTs), which can eventually damage the turbocharger or engine valves.
Q3: Why are there so many part numbers for this one item (e.g., 359-9393)?
-
A: Caterpillar often updates part numbers as they refine manufacturing processes or change suppliers. 281-3587 and 359-9393 are functionally identical and follow the same fitment standards for the 345D/349D lineup.
