No its 3 years old, but an aftermarket. Maybe its just poor quality?

my m103 used to run around 80C constantly, but due to a crack in my original coolant tank, I was forced to replace it today and did an entire drain/refill of the system along with a new 87C thermostat

now it seems to run at 87C only when I am driving 70mph on the freeway night or day. When I am cruising in the city, it starts creeping around 95C to 100C.

What sensor is this and do they have them for a 300TE

I have heard about this, how is this done? and does it do the same thing as the low fan sensor mentioned above?

If your radiator was not plugged internally and the fins were just dirty couldn't you just clean the radiator and it would be fine?

I had read about a fan clutch for the M103 that is used in hot (extreme) climates, Does anyone know about this? or have the parts number.

It's also summer now, so you're probably running your A/C AND there are two thermostats for the M103.

I wouldn't consider nearly 70°F cold.

You have the hotter thermo is the car, it doesn't begin to open until 87°C There are going to be tolerances between parts, system may not be burped, etc.

I don't consider 100°C too hot for the car.
