I've seen a few similar problems in this forum, but none quite like mine. The local garage had it for a day and had no idea, so I need some expert advice really.
I own a 1989 Mercedes 190E Manual. I only get an overheating problem when running the car for around an hour. At this point if the car is running idle, I've got abour 20 minutes until my radiator blows. It's happened once, and will happen again unless I get this sorted.
When running idle the temperature keeps on going up and up. However, when pulling away in 1st at temperatures over 100c, I hear a loud clunking sound, a bit like a belt slipping actually. So presumably the cooling system and the clutch are connect at high temperatures?
Can anyone shed any light on this one for me please? I've only got 100k on the engine.
The RAC geezer said it's either the thermostat, gasket, fan, or something else. I've read about a fan clutch in a few forums however.
Thanks in advance,
