Komatsu Forklift Radiators

This page lists 32 Komatsu forklift radiator listings: 25 radiators, five hoses and two caps. Each one carries a Komatsu-style part number, so compare the number on your radiator with the ones below.

Thirty of the 32 titles say "for Komatsu," and those are aftermarket replacements made to fit Komatsu trucks, not made by Komatsu. The Komatsu name and numbers serve as a cross-reference for matching your truck and say nothing about who built the radiator. To look for a number directly, search by part number at the top of any page, or browse by manufacturer. The two titles that read "Radiator Komatsu Part #" are the only ones without the word "for."

Komatsu Forklift Radiator Core Types

Where a listing mentions the core material, it says copper/brass or aluminum. Copper/brass is the more common wording, found in six of them, including "FOR KOMATSU RADIATOR COPPER/BRASS 3EB-04-A5111" and "RADIATOR ASSEMBLY(Copper /Brass) Forklift FG20-11" under 3EB-04-21210. Two are aluminum: 3EB-04-A6110, listed at 25 inches, and 3EA-04-41210. Four of the six copper/brass titles write it with a slash and no spaces, one puts a space before the slash and one drops the slash.

Read the 3EA-04-41210 wording to the end. It adds "CHECK BOX FOR LOOSE FITTINGS," which no other title here says. The other 17 radiator listings do not say copper, brass or aluminum, so compare the number first and the material second.

Reading the 3EA, 3EB and 3EC Numbers

Nearly every radiator number follows one pattern: three characters, then "04," then a block of digits and letters. The first block is 3EA, 3EB or 3EC, and the 3EB group is the largest, with numbers like 3EB-04-A5211, 3EB-04-F2110 and 3EB-04-A7210. The 3EA group includes 3EA-04-51110, 3EA-04-F2310 and 3EA-04-A2110, and 3EC appears on 3EC-04-A2510 and 3EC-04-A5210. Of the 25 radiators, fourteen start with 3EB, nine with 3EA and two with 3EC.

Model names are almost absent from this group. The one exception is the radiator assembly 3EB-04-21210, which names the FG20-11 forklift beside its number, so for the other listings the part number is the only identifier in the title. Read the number off the old radiator before you compare.

Dashes are not always typed. 3EB04A5111 and 3EB04A2160 are the same style with the dashes left out, and "3eb-04-A2310" is written in lowercase. Eight listings say "Part #" before the number, like "Radiator Komatsu Part # 3EA-04-F2210," and six carry the word "NEW."

Radiator Hoses and Caps

Five of the 32 are hoses. The lower hoses are 21503-L1102 and 21503-FK100, with 3EB-04-A5121 listed as another lower hose. 3EB-04-A5131 is the upper radiator hose, and 3EB-04-12230 is listed as a radiator hose. The two caps are 3EB-04-11130, marked "14 LBS," and 3EC-04-A5120. All five hose titles read "HOSE - RADIATOR" and both cap titles read "CAP - RADIATOR." For more of them, the forklift hose page lists about 940, and forklift hose fittings lists about 2,200.

Komatsu Radiator FAQ

Are there radiators in both copper and aluminum?

Yes, though copper/brass has more listings. Only two say aluminum, so check the wording of whichever listing matches your number.

Can I buy a radiator cap or hose separately?

Yes. There are two caps and five hoses, each with its own number.

Why do two radiator numbers have no dashes?

Two listings drop the dashes, as in 3EB04A5111 and 3EB04A2160. The other radiator numbers keep them.
