Water Pump - Toyota 2LTII, 2LTE, 3L, 5L - 16100-59257 & 16100-59155

Water Pump - late model Toyota 2LT-II, 2LT-E, 3L, 5L engines.

These engines have a ‘bucket and shim’ style valve train instead of roller rockers that are found in the earlier engines. They can also be identified by the stamped steel valve cover, vs the cast aluminum one that the earlier engines use.

Kit contents:

• 1x water pump
• 1x gasket
• 4x studs

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.
