i have 92 500sel and the vehicle has 130k. the problem is at complete stop i accelate engine hesitates or stalls some time.....
i tryied the sparkplugs, wires rotors cap, fuel injector cleaners, air mass sensors & caliberated at the dealer....but seems the same
and recently i notice the temp of the engine going up due to engine coolant loss but it seems to me that coolant is over flowing through the over flow by the radiator... is this normal? and when i have radiator cap open to see what is going, as soon as thermosat opens up i see foaming of coolant and little bit later i see coolant over flow... is this normal...
friend of mine tells me that i have gasket or head crack but need help....

I hate to say it, but I agree with your friend. The symptoms indicate a leaking head gasket. I suggest a coolant system pressure test.

Sorry[:(]

i did the block and head gasket test to see the blue fluid turns to yellow but the blue fluid stayed the same... but is it suppose to foam in the radiator or else?

I don't know about the dye, but it's common for coolant to be pushed back out by exhaust when the head gasket has gone bad.

Have you had a mechanic check it yet?
