Hello,
I will be doing an engine flush on my truck and since it has 145k on it I want to go ahead and change out the thermostat too. not sure what degree the stat is, so 2 questions I have.
1- what is the degree on the stat in the truck now?
2- can I put in a lower degree stat so it will run cooler?
2009 f-150 Lariat 5.4L V8
Thanks for any help.
OK, MAKE THAT 3 QUESTIONS. SPARK PLUGS--WHAT KIND? SAME ENGINE.
