Astro Van M V6-262 4.3L VIN Z (1994)
The front engine mounting brackets use hollow engine mount bolts to retain the engine mount bracket to the engine. The purpose of these bolts is to
allow the engine assembly to break free of its mount in a very extreme frontal collision situation.
When raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal, or crankshaft pulley. Due to the small
clearance between the oil pan and the pump screen, jacking against the oil pan may cause it to be bent against the pump screen, resulting in a damaged
oil pickup unit.
Do not use air tools to remove the hollow engine mount bracket bolts. This will snap the bolt heads off, requiring removal of the thread portion of
the bolt from the engine block.
Do not reuse hollow engine mount bolts. They are coated with Loctite and must be replaced when removed for any reason.
1. Remove mount retaining bolt from below frame mounting bracket.
2. Raise front of engine to remove weight from mount and to place slight tension on the rubber cushion, remove mount attaching bolts, then the
mount. Check for interference between rear of engine and cowl panel. Raise engine only enough to provide sufficient clearance for mount
removal.
3. Reverse procedure to install.
