Common Cooling System Symptoms

• Engine running hotter than normal
• Slow warm-up or unstable operating temperature
• Coolant flow issues caused by a sticking thermostat
• Temperature fluctuations during stop-and-go driving
• Overheating concerns in Jeep Grand Cherokee, Dodge Dakota, or Ram 1500 cooling systems

Installation Notes

Verify the 195°F temperature rating and sealing flange dimensions before installation. Inspect the housing and sealing surfaces for corrosion or debris, and replace the seal if the mating surface is damaged. The jiggle pin weep hole helps with air bleeding during fill-up, and the offset design should be matched to the original thermostat orientation.
