The second part of your statement is incorrect and was removed.

Also.. you are incorrect as well, because some complete dips#it must have given you some bad information, and if they removed that oil thermostat.. YOU NEED TO RE-INSTALL IT A.S.A.P!@.



===========
IF the oil thermostat was removed or missing,.. the oil will overheat on a whim.

This is because the oil thermostat is normally open and BYPASSING THE OIL COOLER!...






.. AND CLOSES AS THE OIL GETS HOT... BLOCKING OFF THE BYPASS CIRCUIT AND FORCING THE OIL thru the oil cooler as it gets hot.



I.E.> ...
WITHOUT THE OIL THERMOSTAT INSTALLED.. THE OIL WILL OVERHEAT VERY QUICKLY because there is nothing at all forcing it thru the oil cooler any more, AND THE BYPASS CIRCUIT THAT IT SITS IN, IS ALWAYS WIDE OPEN!.



If some complete dumb$tard told you to remove it, or that it did not have one, then they are a complete idiot!.
