1999 C43 smells "hot" after running it

[gr0ver]

Not sure when the coolant was last changed in the car, or if the aux. water pump is working (how do I test that, just see if it's working when I turn the car off?). Just replaced the fan clutch, but now whenever I drive the car the engine just smells....hot. Never did before, the temp gauge is fine, it just smells like somethings hotter than normal under the hood.

Thinking of going with a coolant flush, but anything else I should be concerned about? To check?

Thanks!

You sure it's not the smell if burning oil? Valve cover gaskets on those leak all day long

Not oil, already resealed the VC gaskets. Not coolant or electrical, it just smells....hot. It's hard to describe.

engines get hot when they run....... LOL

Gee, thanks for that astute observation LOL. It smells kind of like hot rubber, but not quite. I'm pretty sure all the hoses are original, though I'm not entirely sure, and I have no clue when or if the coolant was ever changed out.

I would say if the temp shows normal, all the fluids and fine and nothing leaks I wouldn't stress about it. Depending on your location it's fuqn 108 where I live, shits gonna cook!!

Mine smells exactly like that too, it gets quite warm here in Australia. Car is fine though, no issues.

I used to own two C4 Corvettes, so things like this dont bother me

At this time of year, anwhere from 3°c to about 25°c, its winter now. Ive seen it over 45°c in march this year.

lol , not the outside temp , coolant temp. sensor


This is from another MB forum:


"note that the cooling system is pressurized (see below), so you can go over 100 degrees Celcius ( to 120 I believe ) without danger for the engine.
From Heynes manual we have the following info for c180, c200, c220, c230, c250:
pressure cap opening pressure :1,4 bar
Thermostat :
Petrol engines:
Opening commences :87 (plus minus 2) degrees Celcius
Fully open:102 degrees Celcius
Non Turbo diesel engines:
Opening commences :85 (plus minus 2) degrees Celcius
Fully open:94 degrees Celcius
Turbo diesel engines:
Opening commences :80 (plus minus 2) degrees Celcius
Fully open:100 degrees Celcius"

Oh ok, wondered why youd ask ambient temps!!

Both my 202s sit about 80-90°c
