1992 Mercedes-Benz 500SEL Problems

Coolant Leak Due to Cracked/Broken Heater Core Outlet Housing

A cracked or broken heater core outlet housing can cause a coolant leak near the bulkhead (firewall). Our technicians remind us that coolant leaks should be repaired in order to avoid overheating the engine due to coolant loss.

Electrical Issues Due to Degraded Engine Wiring Harness

The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

High Usage Vehicles May Experience Ignition Lock and Tumbler Failures

Due to wear, high usage vehicles can experience ignition lock and tumbler failures. The ignition lock cylinder will generally require replacement to correct this concern.
