156 temperature

Hello,

I think I'm having an issue with the temperature of my 156 1.9 jtd
sportwagon.
Nomatter how far I drive, the temperature never reaches 90°C.
It keeps displaying about 70 °C, sometimes a bit more. I also have the
impression that the engine is never really warmed up, especialy when
accelerating in 1st en 2nd gear.

Should a diesel engine really reach 90 °C or I am a just paranoid?

Full agree with you, new diesel engine, especialy with "common rail" like JTD
and HDI are design to work at low temp, near 70°C.
Now a lot af cars are equiped with this auxilary interior heater, even in
France witch is not a very cold country in winter.
A petrol engine must run near 90°c but not a diesel one.

Bruno.

Now I am confused...

I'm hearing several versions here, and my dealer says that my thermostat
needs to be replaced and that my engine should be at 90°C...
Will the replacement of my thermostat be a zero operation?

Thanks guys for al the interesting threads !

That's my experience too. Not quite 90°C but close. Oh..and just how
accurate is my (or your) temperature gauge anyway?

>Will the replacement of my thermostat be a zero operation?

Only if it's not faulty! ;-) If I were in your position I'd change
the stat first anyway.

Mine usually sits close to 85°C. On very cold days, the aircon can
drive it down to about 70°C. I've never seen it get to 90°C. It is the
2.4 though.
