Nissan: Abnormal Noise From Front Engine Mount
A single thunk noise may be heard during the first few accelerations of the day from this type of mount, and is considered normal operation.
Diagnosing Active Motor Mounts On Asian Vehicles
Many automakers, including Toyota and Honda, have changed their lineup of engines to improve fuel economy and emissions. Gone are the high-revving 1.8L and 2.0L four-cylinder engines. Replacing them are engines with displacements ranging from 2.3L to 2.5L. These engines are more efficient and produce more power lower in the power band. But, these new engines increase the stroke and not the bore, making for some unique vibration conditions the motor mounts have to minimize.
VIDEO: Honda’s ACM Active Motor Mount System
Jason Stahl discusses active motor mounts, specifically Honda’s ACM system, and how it communicates with the BCM. Sponsored by Intermotor.
Motor Mount Logic
Engines have noticeably changed in the past decade. Fewer cylinders, more power at lower RPM and more detectable vibration at idle are just a few of the differences in today’s engines. With these changes, it should be no surprise that engine and transmission mounts have taken on new importance. New technologies are being used that access information from the engine to anticipate vibration before it reaches the driver.
Bad Engine Mounts: More Than Just a Bad Ride
Because they are so critical to the vehicle’s handling and performance, hydraulic engine mounts should be carefully inspected to make sure they are working properly.
Audi: Vibrates at Idle
Complaint The customer says that the check engine light is on and that the vehicle vibrates at idle. Cause The customer’s complaint is confirmed, with the vehicle vibrating at idle, but the vibration was not felt at high speeds. A scan tool found code P1573 – Left Engine Mount Solenoid Valve (N144) Open Circuit (17981).
Tech Feature: Active Motor and Trans Mounts
Motor mounts serve an important function: They support the weight of the engine and transaxle (or transmission), and also isolate engine vibration from the rest of the chassis. With so much emphasis on controlling noise, vibration and harshness in late model luxury vehicles, it was inevitable that sooner or later motor mounts would go electronic.
Giving Off Bad Vibes: Motor Mount Replacement Tips
Most motor mounts are relatively simple in design and consist only of metal attachment plates and large rubber insulator blocks. But, some vehicles have “hydraulic” or “hydro-mounts” with hollow chambers filled with glycol or hydraulic fluid.

Anchor Industries Adds 229 New Engine Mount Line Numbers
All new numbers are now available and account for more than 84 million vehicle applications, which represents approximately 9 percent of the total U.S. vehicle registration.
Tech Tip: Chrysler Engine Mount Noise
I know the majority of you auto techs are extremely proficient at finding and repairing sources of strange and unusual noises. Although chasing these audible emissions can be time consuming and without a doubt aggravating, the customer’s concerns are usually valid and can often be of monumental importance to them.
