Chevrolet 89060390 2.2L 134ci Remanufactured Long Block

Blown head gaskets at the rear cylinder fire ring cause sudden cooling system overpressurization on light delivery trucks. The Chevrolet 89060390 2.2L 134ci Remanufactured Long Block cures head gasket separation throughout this commercial long block repower. This 4-Cylinder 120HP pushrod motor demands timing chain tensioner shoe inspection prior to front cover installation.

ASTM A48 Class 30 gray iron forms the engine block casting paired with an aluminum cross-flow cylinder head. A precision-ground nodular iron crankshaft spins in tri-metal copper-lead bearings inside two-bolt main caps. This Chevrolet engine core demands a 12V 140A starter draw during cold morning starts. Total dry weight is 235 lbs, measuring 23in length, 21in width, 25in height, with a 4.0 quarts oil capacity.
