Ok guys, about two weeks ago I replaced my stant 195 degree thermostat with a motorad 195 with jiggler valve. My engine runs much cooler now around 150-170 degrees. Ran right around 210 with the stant without a jiggler valve. Is this a problem or concern? And will lower operating temperature affect mpgs? Should add I checked the thermostat in boiling water and my laser gauge confirms, all temperatures are right.

Hey guys my xj just started making a horrible squeaky noise coming from what feels to be almost under the brake pedal/front driver tire area. My tie rod ends are good and so are my ball joints. What could this noise be?
