- For manual-transmission-equipped vehicles: Have an assistant stand to the side of the engine compartment to watch the top of the front engine mount. With the engine running at 2,000 RPM, slowly engage the clutch. Your assistant should be looking for contact between the top of the engine mount and the bottom of the engine mount bracket, and listening for noise from that area.

With your foot firmly on the brake pedal, quickly depress the accelerator pedal and release it. Your assistant should be looking for contact between the top of the engine mount and the bottom of the engine mount bracket, and listening for noise from that area. - If there is contact and/or noise, go to REPAIR PROCEDURE.
