Over heating m110 engine

Started by Magyar, 27 March 2024, 06:30 AM


Hi, all of the M110 powered 280se cars ive owned overheated, why do these engines always over heat?

How do I prevent it from over heating?

Generally these cars need entire system to be in order. Radiator, fan clutch, thermostat and water pump. And ac fan.

Ditto to the comments by rumb'

I've only overheated 2 times in my cars 45 year ownership.
Both times was down to some part of the system being worn or dated.
And just recently I discovered the system losing water. It was simply simply a faulty radiator cap.
I've taken the radiator out 3 times now, roughly every 10 years and sent it off to be professionally cleaned in an acid bath. Perhaps thats kept it in good stead.
