Hi all,
- I've got a US 1993 400e with 108k miles. Owned the car for 2.5 years since it had 98k miles.
- It's a California car and it spent most of its life here. Car drives very well with full power.
- When i bought it, it was in very good condition. I've since invested about $14k in it. $9k in preventive maintenance and $5k in transmission rebuilt + repair concerning radiator/fan clutch etc.
- Since day one temperature in the city would hit 105C then be brought down by kickin-in fans, then repeat all over. Temperature never ever went above 115C on my watch, and that's in a fully loaded car, going uphill on freeway, on 100C day, 85 mph at full throttle.
- Eventually i did transistor mode, and now my car almost never touches 100C.
- Used oil analysis show no coolant in the oil at all, and is perfect report
I took it to specialized-in-mercedes-only mechanic last week, and he's telling me it's a head gasket. Per mechanic, the large front hose by the radiator is stiff after 10 minutes from start up, and removing cap causes coolant to bubble over. $4,300.
What do you all think? Your thoughts are much appreciated.

. With out You, I'd still be in doubt if it was a fan clutch issue [respond to my PM!!!!!
