Last week, i replaced my valve cover, water pump, fan clutch, intake manifold gaskets, and TB gasket and have since had erratic coolant temp readings. The gauge normally stays a few ticks above half when idling for extended times and right at half cruising on the hwy. the thermostat was replaced 2 years ago so it is not the stock 180 degree as the gauge readings have always been slightly higher since it was replaced.
Since the replacement of the above listed parts, the temp gauge rises much faster to slightly above half and will continue rising to almost 3/4 local driving and go back to slightly above half when on the hwy. i've monitored the temp readings with the dashcommand app and verified with my scantool. normal operating temp for the past 2 years has been 199 degrees but the recent spikes have gone to 219. Today has been the hottest day since the parts were replaced (85 deg) and cruising on the hwy, the temp spiked out of nowhere to a little above 3/4 at which point i opted to suffer and crank the heat. temps came down but never to where they should be.
I have monitored the coolant level daily and driven about 500 miles since doing the work and the levels have been right where they should be. Heat also comes out of the vents super hot. I'm assuming the thermostat may be getting stuck and not fully opening as i've never experienced the temps get anywhere near as hot as they have been.
A second concern of mine is with the fan clutch. The old one would have a whirring sound upon startup that would always stop when i reach second gear. the new one does it indefinitely unless i go through a gear at WOT. All of my research says that the sound is from the oil in the clutch redistributing throughout the clutch. could the new clutch be faulty and causing the high temps?
