The test me and rizla have done are with the car idleing in his garage,


Both stas have 82.c on the bottom of them which is i assume the temperature that they are ment to open at, but the new one he got
from ford's is opening later than his old stat,we put both stats in a
sausepan and watch them both to the boil and the new stat only
opened right near to the boiling where as the old one had fully
opened by then which make's me think that they are a bad batch
of thermostats ford's are supplying or as stu has said there crap.

What ive suggested to rizla is we put the old stat back in the
car and go for a good drive in it putting it under load and normal
driving and see where the car s temprature is at!
