AISIN Water Pump | 2L / 2L-T Diesel (1984-85 Pickup)

AISIN Diesel Water Pump

For 1984–1985 Toyota Pickup equipped with a 2L diesel or 2L-T turbo diesel engine, with 2L 4WD fitment limited to 1984 and 2L-T fitment limited to 1985.

Overview

This AISIN water pump replaces the front pump assembly on U.S.-market 1984–1985 Toyota Pickup 2L diesels and 1985 2L-T turbo diesels, with 2L 4WD fitment limited to 1984. It retains the engine-side housing and original pulley-drive arrangement.

Key Features

• Cast-aluminum housing with a stamped-steel impeller.
• Mechanical accessory-belt drive uses the original water-pump pulley and fan coupling.
• 77 mm hub height for the early diesel pulley and fan-coupling arrangement.

Vehicle Fitment

Toyota Pickup — 2nd Gen — U.S. models

• 1984–1985: 2L naturally aspirated diesel, 2WD.
• 1984: 2L naturally aspirated diesel, 4WD.
• 1985: 2L-T turbo diesel, 2WD or regular-cab 4WD.

Fitment Notes

• Diesel engine identification matters: the 2L and 2L-T use a different pump from the earlier L diesel and the 22R / 22RE / 22R-TE gasoline engines.
• Engine swaps or changed front-drive components require matching the installed engine-side housing, pulley and belt alignment rather than the truck's model year alone.
