Temperature Gauge (Position)

[Dromara1974]

Hi All,

I was just wondering where the needle should sit in the temperature gauge when the engine is at operating temperature, as my needle sits a bit west of vertical and this just seems odd.

My car also continues to rev at 1500rpm a good 10 mins after starting and it seems to take ages for the engine to get warm. The Lexus garage told me that the 1500rpm was part of the dpf regeneration process, but I wouldn't expect it to do this every day; or does it!!?

I'm wondering if I have a faulty thermostat and this is why it takes along time to get warm, and is perhaps why I use a lot of fuel and lack power - the engine is making the injectors run in cold-start mode when they shouldn't and over-fueling the mixture.

Any thoughts?

Cheers

David

hi, i have the 250 and had the same concern, the gauge sits slightly off centre to the left as yours does, and takes well over 10 mins of driving to remotely become warm. The Lexus dealers said this is normal for them because it is a large engine block. As for diesel they always take longer anyway due to less heat produced when diesel burns compared to petrol.
