well my car started to overheat, so i replaced the thermostat and that seemed to fix it for a few days and then it overheated again so i replaced the radiator with a spare it kept going for a few more days but then it overheated again.. WTf?/ any ideas?

Check radiator cap for cracked gasket bad spring, the seating surface for corrosion. Fan clutch could be bad too. Could be plugged radiator.

Does it overheat while cruising, or during stop and go?

After it is warmed up, turn it off, and carefully! check the radiator for cool spots (or spots that are not as hot as others).

good luck

Did you replace it with a used radiator or a new radiator? What temp does it usualy run. With a perfect cooling system it should stay at about 80C regardless of conditions or load.

Could be the head gasket as well, lots more info is needed.

Have you pressure tested the cooling system?

Is this while stopped or while moving? First determine if you think it is a coolant flow problem or an airflow problem or a combination of both. What temp is it reaching?

Why don't you just go find a reputable repair shop?????????
You need to determine when this overheating happens.

Freeway or in town

Does it help to turn the heat on, and not a/c and heat, use the ec button

is it full of the right mixture of coolant? Many people don't know that coolant does not dissipate heat, that's what the H2O is for

I would suggest finding a repair shop that can answer some basic questions before bringing the car in to be check out.
FYI, I have never seen a Benz head that was making the car overheat. At least as far back as my memory can remember
