Is my thermostat stuck open?

[Jimm218]

Hi All,

I'm wondering if my stat is stuck open and wanted to compare the readings I'm seeing with other peoples.

On my 4.2 last night at 70mph both temp readouts were giving 75C and weren't getting any higher. Slow down to 50mph and it might creep to nearly 80C. Heaters weren't blowing much warm air into the cabin either so I'm fairly sure the stat is lazy (which would make 3 of my 6 cars with the same issue!)

What are other people seeing this time of year?

Its possible I guess but I think it is an original. Don't recall anything in the paperwork to suggest it has been changed.

Thanks all. Sounds like it is close to normal. I might change it next time it is all apart to see if it makes any difference.
