Mercedes-Benz 300SE Problems

Repair Leaks From Head Gasket/Timing Cover Gasket Before Oil and Coolant Intermix

Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.

Rough running motor/lack of power due to failed ignition coil packs/spark plug resistors

Failed ignition coil packs or spark plug resistors can cause a rough running motor or lack of power.

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.

Mercedes-Benz 300SE Reviews

I love my Mercedes Benz SE 300. The only problem i had are with the window regulators (Front Passenger, Rear Passenger). They was both working but didn't work with the one touch option because the gears was strip. mjg429mach1@yahoo.com Richmond,VA
Love this car, I have owned many cars over the past 45 years.This one with the exception of a few small problems has been the best. 193,000 miles, still running strong,looking great, and getting compliments.no one believes the age and the comfort is beyond compare.I'm sold on M.B.
Car is garbage. Wiring harness falls apart. All of them need to be given, not sold, to scrap yards.
