We have the highest quality Toyota water pumps in stock all of which are new OEM quality Japanese-manufactured (Nissan or Aisin) pumps, not cheap Chinese rebuilds. Gasket is included with the water pump. Don't be left stranded or damage your new or rebuilt engine because of a simple water pump. If you have any questions feel free to give us a call and we would be glad to help.This water pump is also utilized in our Dual Row Timing Chain Conversion Kit's Part # 1015012
The most common water pump failure is due to over tightened V- belts. An incorrectly adjusted fan belt may shorten the life of the belt or the water pump. After you install your belt you should have 5/8 in. to 3/4 in. of slack when pushing the belt with your thumb. The belt can be twisted about a quarter turn when the tension is correct. As per a Toyota Factory Service Manual, the drive belt should be 125 +/- 25 lbs. measured with a Nippondenso BTG-20 (95506-00020) or a Borroughs BT-33-73F.
