Hot Cop Cars
Some owners of 2013 Chevy Caprice vehicles may comment about roughness or vibration felt at stops and a clunk from the driveline on acceleration from stops. This may be caused by a broken motor mount.
When vehicles sit idling for long periods of time, heat builds up in the engine compartment. A hard acceleration can rupture either the left, right or both of the hydraulic mounts. This issue is more likely to occur with police vehicles that idle for long periods.
A new mount has been developed that is more resistant to heat. The new mounts are available as P/N 92259641.
