2000 CLK 320 overheating problem

[lizk]

Hi folks

I have recently bought a 2000 CLK320 convertable. On my 3rd outing I noticed the temperature go from around 80 to just under 120 and rising. I pulled over before it boiled up, and lifted the bonnet. The fan was not running.

Being a girly I could do no more so after 5 hours of RAC faffing about to get me home, my other half had a look. The fan runs when connected to another power source, so we guess it must be some sort of switch or relay. I went in to see the very helpful (I wish) spares department at MB, who advised that there was no switch but I would need to replace both the regulator and the fan (at a cost of about £270 plus VAT supply only)

Does anyone know any more about this problem, or offer any suggestions?

Thanks Liz and Barry

Have you got this fixed? Have you checked the engine thermostat? even if the thermostat was not the prime cause of the over heating, the boiling of the coolant is likely to have damaged it....Could be an air lock in system....did overheating occur in traffic or on an open road?
