I have an '86 190E 2.3-16V (US spec). WHen I sit at idle the temp. raises up and wants to keep going, the fan won't kick in like it's supposed to at 100 celcius. When the traffic clears up and the car starts moving the car cools down though. So that tells me that my cooling system is good. It's just that dang fan. I'm told that it is more than likely my fan clutch and/or the sensor for the fan. I'm also considering a fan actuator switch of some sort. Please MB gurus, enlighten me. I already ordered a Mosselman turbo kit for my car and I don't need the thought of overheating engine to keep worrying me. Thanks again MB gurus. Later.
