MK6 Fiesta ST Below Running Temperature
Hi guys,
For a a couple of months now I have been noticing my temperature needle floating around between the mid way mark (Where it should be) and the mark below, sometimes even touching the mark below.
As a consequence, the fuel economy seems to be suffering. It could be the colder weather but the drop of 5-10 mpg seems a little extreme for that.
My question is, is how likely is this issue related to the thermostat or whether it's related to a sensor issue? Are there any ways that I can easily tell which issue it might be?
Thanks in advance

Thanks for the reply Yeh I've noticed that it seems to be an all in one unit, where exactly is it located? I changed the coolant during the summer which is a pain in the arse if I lose it all trying to change the thermostat! Will have to try and replace it without losing too much coolant

It's at the left end of the manifold (looking from the front), nestled just under and to the right of the power steering fluid reservoir. Access is tricky, a bit easier if you take off the offside headlight.

Hey bud, is this definitely doable without taking the front of the car off? I'm looking at tit as we speak with the headlight off and the top right bolt seems like its directly behind the intake and would be impossible to get to? Be great if you could let me know

Gocha! Sounds like that could help as well, though I think getting the hoses off looked like the easiest aspect of the job!

that was the hardest part, i needed 2 hands to pull the pipe off, but then another hand to use the clamps
after 4 hours of struggling and swearing my dad wandered past and i got him to hold the clamps
then it was a 5 minute job replacing the housing and then putting the pipes back on again
the bolts are easy to get to with a small ratchet and the wiring plug is also a doddle to remove, it's just that hose clamp as you have to bend the pipe to get it over the lip in the plastic before it'll come off and the same in reverse
if the front slam panel wasn't in the way it would be but a moments work

Yeh that's it! Well, I seem to have bigger, gearbox shaped problems now to top it all off, so thermostat can wait! xD
