If your Dodge Ram 1500 is experiencing overheating problems, it can typically be attributed to a few potential factors. A simple first step is to check your coolant levels to ensure they are above the minimum line. A low coolant level may indicate a leak that needs to be repaired. Additionally, a failed water pump could be hindering the proper circulation of coolant throughout the system. Another common culprit could be a faulty thermostat, which is a relatively easy fix to get your vehicle functioning properly again. While there could be other underlying causes, it's advisable to schedule a check-up for your vehicle to pinpoint the exact issue.

Here's a paraphrased version:

I own a 2018 Ram 1500 with a 3.6-liter engine that's experiencing overheating issues. Despite replacing multiple components in the cooling system like the radiator, water pump, thermostat, and more, the problem persists. The engine temperature fluctuates between 225-250 degrees Fahrenheit after running smoothly for about 20-25 minutes. I've been told that these engines are difficult to properly burp. My truck is five years old, has 74,000 miles on it, and I'm still unable to resolve the overheating problem. Interestingly, the interior heat only starts working after driving for 3-4 hours, not immediately. All the parts I've used for replacements are Mopar brand. Has anyone encountered similar issues where the temperature suddenly drops?

I hope this helps clarify the issue you're experiencing with your truck! Let me know if you need further assistance.

I replaced the fan clutch, thermostat, and water pump. I also flushed the engine block, radiator, and heater core, but the issue persists. Any other suggestions? Should I consider switching to a lower thermostat, maybe below 203 degrees?

The primary reasons why a dodge ram 1500 might overheat are a coolant leak, a malfunctioning thermostat, or a problem with the radiator fan.

Replaced the water pump on my truck because the water pump bearing went bad, and now I'm experiencing overheating issues even though it never overheated before.

It seems highly probable that your head gasket is blown.
