Can't find your part? Read us the numbers off the tag or the old part: (804) 333-3677 (Mon-Fri 9-3 ET) or send us a message.

We stock 35 active Cummins cooling parts: oil coolers by diameter (2, 3 and 4 inch), heat exchangers for 4-cylinder and 6-cylinder engines including the newer 5.9 6-cylinder, 5-inch-diameter units 27 inches long, a fuel oil cooler and an expansion tank. Most come in copper-nickel (CuNi), many with a standard version alongside.

Replacing a transmission cooler? Chris's rule is about every 5 years in fresh water and every 2 years in salt, and right away if metal or water has gotten into the transmission, since metal stuck between the tubes can't be flushed out. See our heat exchangers and coolers guide, or call (804) 333-3677, Monday through Friday 9 to 3 Eastern, if you're not sure which part you need.
