Customer Complaint
I received a call from a customer in Antioch about their 2019 Dodge Journey having temperature-related issues. They wanted it checked before it turned into a bigger problem.
They mentioned:
Engine temperature fluctuating

Wanting to prevent further damage
These are common signs of a thermostat issue.
Diagnosis Process
When I arrived, I performed a cooling system inspection.
Findings:
Thermostat was not regulating engine temperature properly
Cooling system performance was inconsistent
No major leaks found in the system
The thermostat controls coolant flow and plays a key role in maintaining proper engine temperature.

Steps performed:
Drained the coolant system
Removed the faulty thermostat
Installed a new thermostat
Reassembled components
Refilled coolant with correct mixture
Bled air from the system
Tested engine temperature operation
Total time on-site was about 1–1.5 hours.
Result
After the repair:
Engine temperature stabilized
No more fluctuation issues
Cooling system operated properly
Vehicle ran reliably without overheating
The customer avoided a more serious engine issue by addressing it early.
