Chevy 350 Motor Mount Bolt Size

When it comes to selecting motor mount bolts for a Chevy 350 engine, there are several factors to consider. Mechanics need to take into account the torque specifications, thread types, parts overview, and anti-seize lubricant. By understanding the importance of each factor, mechanics can ensure that the right bolts are chosen for a successful installation.

Torque Specifications

When tightening motor mount bolts on a Chevy 350 engine, it is essential to follow torque specifications. OEM manufacturers typically provide different bolt torque recommendations than aftermarket suppliers. Therefore it is important to check with the vehicles owners manual and/or other sources for the exact torque requirements. Applying too much or too little torque can lead to problems such as bolt failure or insufficient clamping force.

Anti-Seize Lubricant

It is recommended that anti-seize lubricant be used when installing motor mount bolts for a Chevy 350 engine. This lubricant helps reduce friction between two surfaces that may be exposed to high temperatures and vibration from everyday use. Anti-seize lubricants come in both oil saturated and non-saturated varieties, and should be applied in accordance with the manufacturers instructions for best results.

Bolt Thread Types

When selecting motor mount bolts for a Chevy 350 engine, it is important to pay attention to the thread type of each bolt. Thread pitch identification is essential when choosing parts as differences in thread size can affect performance and reliability of an installation. Generally speaking, metric threads have higher strength than imperial threads due to their larger diameter size.
