1997 Mercedes Benz E320 overheating problem........please help!
I have a 1997 E320 with 1,70,000 miles on it now. This is my daily driving car.
Recently(may be a month) an overheating problem started on it, and it overheats after I drive about 20-30minutes on normal road from cold, or when I get down from the freeway.
On the freeway temperature is okay. And also, temp gauge always shows above 90-95. ALso, electric fan always comes on even when starting the engine on cold (overnight stopping)
I have checked with couple of mechanics, to know the exact problem and how much it would cost me.
1st mechanic version:
He told we would need to replace radiator (because it is clogged) and also replace fan clutch. Gave an estimate of around $650.
2nd mechanic version:
He had the car for almost a day, running different tests.
He told, he checked the radiator, fan clutch, water pump, fans, temperatures overall, and everything looked normal to him.
And then he said the big problem thing.
He told, he did a test in coolant system, which shows him different colors for different problems, and there he could see something different kind of bubbles or change in color test and he was thinking that there might be a air crack in engine's head part, which is hard to fix. He was telling something like exhaust coming into coolant ( may not be the right wording) when he tested with his tester. And he recommended, to get rid of the car instead of trying to fix it.
Please help me with your thoughts, and help me with any fixes you would like to recommend before going any further.
