Water Pump 3B & 13BT - later models - 16100-59105

Water Pump for Toyota 3B & 13BT diesel engine - from 1982 model year & later

Land Cruiser BJ60, BJ70, BJ71, BJ73, BJ74, BJ75 & related vehicles with late model 3B engines.

Toyota pn: 16100-59105

Fitment Note: These pumps do not suit early 3Bs with 6mm fan studs.

This water pump is for the 1982 and later model year (~08/1981 is the transition time frame). If you unsure, please provide your VIN or Chassis numbers for us to confirm your application.

Pro Tips: Water pump life is affected by factors such as coolant concentration and quality, belt tension,  operating environment and engine hours.

Coolant concentration in the cooling system should be at no less than 50% coolant, and 50% distilled water. We suggest using a 60/40 concentration since when an engine is flushed with clear water to remove the old coolant, some water is left behind that may reduce the effective concentration to below 50/50.

Coolant not only prevents overheating, it also provides lubrication for the water pump and has corrosion inhibitors in it to reduce internal engine corrosion and electrolysis as well as premature gasket failures (where gaskets are exposed to coolant -such as the cylinder head gasket).

Also, replace your rad cap at the same time... it's cheap insurance against overheating. You would not believe the number of original rad caps I have seen that are still on Land Cruisers from the 1970s and 1980s... that have long since stopped operating properly.
