Hey everyone,
My stock radiator finally broke at the upper plastic hose connection. Prior to breaking, it was running 210F pretty much no issues. It jumped up a bit in traffic, but never got to any worries of overheating.
I just replaced the radiator with a Duralast unit (likely Spectra). I did not change anything else other than fully flushing the system again (I did that about 1.5 years ago as well). Using Prestone 50/50 premix.
Fan clutch is loose (with a little friction) when cold. Thermostat was closed when I checked it during the flush (Gates 195F, replaced 1.5 years ago), electric fan only turns on when A/C compressor is on. Water pump is a new Mopar unit also replaced 1.5 years ago.
At idle with HVAC off or A/C blasting...it does not get above ~184F measuring with IR thermometer on the thermostat housing. (I am in 20F weather right now, but that has never changed my operating temps before) Gauge in the dash matches this. Opening up the heater bring the temp down further (heater valve is bypassed).
Any other thoughts? It's clear my gas mileage is suffering quite heavily after watching it for half a tank.
Thanks!
