Ride Control Complaints

We Examine 5 Common Customer Issues 
Ride control complaints are one of the most common types of concerns expressed by customers. Quite often, the customer’s description is vague or misleading.  Attempt to gather as much information from them as possible prior to performing an inspection. For example,  do you only hear a “funny” noise when driving n bumpy roads or on smooth roads as well?  If you suspect that the vehicle is heavily loaded with cargo at times, ask if the “wandering” they experience only occurs when heavily loaded, etc. The customer’s descriptions of an  issue should be considered merely as a starting point. It’s up to you to inspect and road test to determine the actual cause of the complaint.

Cylinder Head Gasket Service In Modern Era Engines

A Failed Head Gasket Is Only a Symptom, Not the Root Cause

“My engine blew a head gasket and now it overheats.” That’s a fairly commonly heard knee-jerk diagnosis. However, it’s wrong. When an engine overheats or if the gasket allows coolant or combustion gasses to escape, do not automatically blame the gasket. Cylinder head gaskets can be viewed similar to a fuse. If the gasket “fails,” this is a symptom that something other than the gasket itself caused the failure.

Keeping Up With Change: Continual Research and Education Is Vital

Automotive technicians all have their own individual style and approach to diagnostics and education. But most techs will tell you that if they understand how the system is supposed to work and the components involved, the diagnostic repair journey is usually easier. Automotive technology is constantly changing, it never seems to stop, but keeping up with this constant change is a demanding task.
