Engine temperature.

How long, at this time of year, should a 270 cdi take to reach normal operating temperature ?

 

[Yugguy]

Diesel will take longer when cold, it's normal.

 

[Taffy7hfa]

15 minutes seems too long... even though its at town speeds.

 

[Yugguy]

Mine can take that long if it's cold. If you keep going does it reach temperature?

 

[Taffy7hfa]

Yes, gets to 82.... after about 15 minutes.

 

[Yugguy]

Should be higher than that I think.

 

[Taffy7hfa]

Mmmm, thinking maybe the stat needs replacing.

Mine (E 350) runs a tad hotter 85ish degrees, but can take 15mins to get there, especially if the heater is demanding warmth too...

 

[Taffy7hfa]

It does eventually get to about 84, but that seems to take about 25 mins, and it's not even cold at the moment ...

 

[ajlsl600]

most stats around 88 i think but 15 min does not sound to far out to me. i asume yr not thrashing it.

 

[Taffy7hfa]

Not unless its properly warmed up, generally just country lanes type speeds.

 

[ajlsl600]

does not sound far out, benz might be able tooffer a stat that helps

 

[Taffy7hfa]

cheers

Normal, even in our temps. Even worse with egr disconnected.

My C 270 Estate took about as long as the others mentioned here. Annoying, but normal.The stat should give a 'static' readout once up to temperature. If it fluctuates, change it.

I ran mine with my radiator grill blanked off all year round. Most UK cars are grossly overcooled, and this helped with both temperature and economy.

What a great engine the 270 was. MB's best kept economy secret.

Mums was like that from new. Took about 26 miles to get to 85c ish.
Normal running to shops etc. She never even reached 80c
Made them change the thermostat under warranty, they didnt like that as they said it was quite expensive to do!, and it was much better got to 85 in about 7-10 slow town miles ...
Still nothing like 5.0L V8s that are fully hot , just under 90 C in 2 miles.

Heater boosters can be problematic

Check fault codes

Will do, thanks..
