Description
Caterpillar 435-5142 is a genuine CAT advanced-efficiency, non-pelleted spin-on coolant filter used on Cat-equipped on-highway and off-highway diesels running extended-life coolant or systems where SCA is dosed separately. With an 11/16-16 thread and ~3.66 in body, it crosses directly to Fleetguard WF2073, Donaldson P554071, Baldwin B5089, and Wix 24070, capturing rust, scale, and debris that shorten water-pump and radiator life.
