I have a 351W with a 9qt
oil pan and an
oil cooler.
Oil temp gauge needle rises to just slightly below the 140 mark, never exceeding that, causing me to question whether the gauge works properly. I've tried taping up the cooler opening and the temp rises to slightly above the 140 mark, but no more. Not sure where my temp sensor is located, but will check. Is my gauge wrong or is my oil temp unusually cool?
