Good evening folks.
Picked up a 1990 260e last week to use as a weekend runaround and to tinker with and polish! Loving the car so far (it's a very tidy well specced 1 lady owner car with 100k and FSH) but having some trouble with the engine temp.
It never runs above 60 deg. Had a search through some posts on here and convinced myself it must be the thermostat so ordered a new one from MB and fitted it today. Ran the car for about 20 mins and it's still not going above 60 deg.
The large rubber hose from the top of the rad to the thermostat housing feels empty if I squeeze it, even after running the car for 20 mins with the expansion tank cap off so it's as if the thermostat hasn't opened to feed water into the rad.
So, do you think it's a faulty thermostat I've been given which isn't opening ? If that's the case I thought the temp gauge would quickly shoot up above 60 and that's what's confusing me.
Could it be the coolant temperature sender ? Does this have any functionality other than to feed a signal to the gauge ?
The fan runs continuously on the car - should it be doing this ? Not sure if that's normal or if this is part of the problem.
Any advice much appreciated. Looks like a great little forum here which I look forward to being part of
