Hi Chaps
I thought I would update the thread with some interesting info.
Although the car now heats up much quicker with the new thermostat, its interesting to see some data on this.
The car seems to get warmer only when driven, and plateaus or falls when the car is at idle.
It also never seems to get hotter than 87 degrees which is strange as the thermostat is a 90 degree unit from memory, so if that is true, then the thermostat would never open. perhaps the marked temperature is when its fully open, NOT when it starts to open? An inaccurate temp sensor (was replaced with thermostat housing) could also account for this reading.
Anyway - the data below shows that on the drive to the office this morning, it took 13mins to reach 87 degrees and that included 3 mins at idle (or very near to).
Its interesting to see the air intake temp rose when idling - this may be the cars own heat, or possibly heat from the car in front in the queue!
Anyway - one to study....
