Folks,
I'm wondering about the temp display when the instruments are in TEST mode.
I have a 2007 TDCi. I started it in TEST mode, clicked through to temperature, and saw "89 C" (it had been run a few hours before).
Started the motor, and it slowly increased. Ran it at ~2,500rpm for some minutes.
The radiator hoses only got hot when it reached "125 C". It then dipped to around "120 C", and slowly rose again. I presume the thermostat just opened.
I kept going, and at "137 C", the fan came on.
The dash guage never rose above half way.
Q1. Is this *really* in Centigrade?
Or is it just some arbitrary scale?
It seems pretty darn high to me.
Also, the guage's low mark is marked "60 degrees C", and high mark is "120 degrees C". It doesn't match.
Q2. What values do you folk normally see?
So why am I doing this in the first place?
I'm debugging a cooling problem in a Lotus 7 type car with a 2.0l Duratec from a 2006 Focus. Ok, different motor, but electronics mostly the same, and the diesel is my daily driver. In the 7, sitting still it reached "122 C" with seemingly no thermostat open, and no fan running, before I gave up. The fan works when the ECT lead is pulled. After that, I played with the TDCi as above.
Hope you can help, thanks - Gavin.
