Why does the check engine light come on when I start my 300SL?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your 300SL firing up its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Are Mercedes-Benz 300SL engine noises bad?

Strange under-the-hood noises can point to problems within your Mercedes-Benz 300SL engine. Tapping or knocking could mean you're low on oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my Mercedes-Benz 300SL engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, flooring the gas pedal while the car is in Park, or accelerating too quickly, too soon. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Can I add water to my Mercedes-Benz 300SL radiator?

It’s not recommended you put water in your 300SL radiator unless it’s an emergency. Under normal circumstances, use a 50/50 mix of water and coolant or a pre-mixed coolant. But, if you need to keep driving while out of coolant, using water is better than driving with an empty coolant reservoir.

What could cause my 300SL engine to suddenly stop?

Your 300SL car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
