This water pump is only for the earlier versions of the 2L and 2LTE engine.
To distinguish between early and later versions of this engine, please scroll to read the text that follows.
Toyota pn:
16100-59139
water pump is supplied with a paper gasket and 4 studs for the pulley flange.
Aisin (OEM) - Japan
Early vs Late L Series engines:
• The early engines can be distinguished from the later models as they have roller rockers, the later models have a ‘bucket and shim’ style valve train.
• The other distinguishing feature is the cast aluminum valve cover found on the early engines (later ones are stamped steel).
This water pump is for the earlier L series engines.
Pro Tips: We recommend that you replace your water pump with each timing component (belt kit) replacement. The factory recommended interval for the belt and tensioner is 5 years/100,000Kms. In my experience with these engines, water pump reliability starts to drop off considerably in the 140,000 Km range - some last longer, some don't even last that long.
Water pump life is affected by factors such as coolant concentration and quality, belt tension, and operating environment and engine hours. Replacing the pump at the same time you're doing the timing belt and components saves on duplicated labour as well.
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.
