Hello my peoples. Looking for some help with my ‘12 jk. I’m not super educated on vehicle mechanics so forgive my lack of knowledge in this area. I’m noticing my radiator fan is really loud after a couple miles. It doesn’t sound loose, just sounds like it’s working really hard. I wiggled the fan, seems to be sturdy and operating correctly. The vehicle is not over heating but the heater fails to blow consistent hot air. Only when my foot is on the gas. That being said coolant level is good! What are some tho ya that may be causing this? Things I can check first? Thermostat? Heating coil? Water pump? Big thanks in advance for anyone that can offer some advice.
