This is a new, genuine Kubota EGR cooler, part number 1J070-71410. Kubota’s parts description reads COOLER,COMP(EGR): the complete cooler. It is for the turbocharged common-rail V1505, the 1.5 liter four-cylinder with a DPF, and Kubota dealer parts catalogs list it on LX3310, LX3520 and LX4020 tractors, the F3710 front mower and ZD1611 zero-turn mowers.

An EGR cooler is replaced when it leaks coolant into the exhaust side or plugs with soot. Look for coolant loss with no outside leak, white smoke or steam on start-up, wet soot at the EGR valve and EGR flow faults. Pressure test the cooling system and check the EGR valve and pipes first, since a stuck valve or a plugged pipe can set the same codes. Kubota’s EGR valve for the same engine is 1J377-62702. Kubota ends many EGR cooler numbers in 71410, such as 1J808-71410 for the V2403-CR-TIE4, so match the whole number.
