Thermostat 50C 17670-91J01 for Suzuki DF2.5 DF4 DF6 DF9.9 DF15 DF20 Outboard
Thermostat 50C 17670-91J01 for Suzuki DF2.5 DF4 DF6 DF9.9 DF15 DF20 Outboard
Product Overview
Thermostat for Suzuki four-stroke outboards, opening at 50°C. It replaces Suzuki 17670-91J01, 17670-91J00 and 17670-91J02 and sits in the cooling circuit between the block and the water pump. A stuck thermostat shows up as an engine that runs cold and never reaches normal temperature, a telltale that stays weak, or the opposite — a fast climb into the overheat range within minutes of starting. Supplied as 1 x thermostat.
