How to tell the two C15 pumps apart
The quickest check is the drive gear. The AK-1615719 uses a bolt-on gear and is listed for the CAT C15, while the AK-2243229 uses a press-on gear with an 8 inch opening and fits the C15 Acert and the C18. If the engine is an Acert, start with the AK-2243229, and if you're not sure which C15 you have, the number on the old pump or in the parts book will settle it. Some later CAT 3406E engines share parts with the early C15, so the AK-1615719 may also be the pump for a late 3406E.
A water pump usually gives some warning before it fails, such as coolant at the weep hole, a noisy or loose bearing, or a truck that starts running hot under load.
Replacing it at the first sign costs far less than a cracked head or a truck stuck on the side of the road, so it pays to have the right number on hand before the job.
Common questions
Which water pump fits the C15 Acert?
The AK-2243229, which also fits the C18.
Does the AK-1615719 fit the CAT 3406E?
It may. Some later 3406E engines share parts with the early C15, so call 1 800 247 7669 with the number on your old pump and we'll confirm it.
What if my number isn't listed?
Call 1 800 247 7669 with the Caterpillar number you have, and we'll check if one of our pumps replaces it.
