A brand new engine water pump complete with backing housing, manufactured by Aisin who is the original manufacturer for Toyota for the Hilux Pickup, Hilux Surf & Land Cruiser models with 2KDFTV, 1KDFTV, 1KZT & 1KZTE diesel engine types.

The water pump is bolted to the engine, the viscous fan and fan blade then bolts to the waterpump. The waterpump is complete with a new mounting gasket and mounting studs to mount the viscous fan to the water pump. This controls the engines cooling system by spinning the fan and cooling the radiators which in turn cools the engine down.

Aisin manufacture for Toyota, therefore this engine water pump is as per the original fitment of the original water pump fitted from factory.

RoughTrax are now direct agents for Aisin, therefore pleased to be able to supply this quality Original Equipment (OE) product at a much discounted price.

Please Note:

  • Some earlier models such as on the 1KZTE engines used a pump that fitted into a separate alloy backing housing with 6 bolts revealing the pump blades on the rear, Aisin's new design pump replaces the older 2 piece setup with a more efficient pump and is a direct replacement once you original backing housing has been removed.
  • This one piece pump will take longer to fit as it requires fitting right back to the cylinder block, removal of all the timing belt and associated parts is necessary.
  • If you prefer to simply fit the smaller pump that bolts into the backing outing with 6 bolts then choose water pump Aisin Engine Water Pump without Cast Housing (for certain models), again manufactured by Aisin. 
  • Aisin manufacture for Toyota, therefore this engine water pump is as per the original fitment of the original water pump fitted from factory.

Product Reviews for Aisin Engine Water Pump with Cast Housing

Questions & Answers for Aisin Engine Water Pump with Cast Housing

Do I need anything else when fitting a pump?
You may want to use a thin film of silicone sealant either side the gasket and of course, new coolant is always a good idea.

My pump appears smaller than this pump?
Some earlier models had a separate small pump that fitted into an alloy backing housing behind, this then fitted to the block. Aisin (for Toyota) redesigned this setup to a more efficient one piece pump that simply bolts straight to the block. It's a direct replacement and becomes obvious once the old one is removed.

Thank you for looking through our questions, if there is something you need to know about this or any product please don't hesitate to contact us and speak to one of our experts.
