Customer Complaint
I received a call from a customer in Nashville about their 2019 Toyota RAV4 running hotter than normal and showing signs of a cooling system issue.
They mentioned:
Temperature gauge rising higher than usual
Occasional coolant smell
Concern about overheating
Wanting to fix the issue before it got worse
These are common signs of a cooling system problem.
Diagnosis Process
When I arrived, I performed a full cooling system inspection.
Findings:
Water pump showed signs of wear and potential leakage
Thermostat was not regulating temperature properly
Cooling system performance was compromised
Both components work together to maintain proper engine temperature, so addressing them at the same time is often the best solution.
The Repair
To restore proper cooling system function, I replaced both the thermostat and water pump.
Steps performed:
Drained the coolant system
Removed the faulty water pump
Removed the thermostat
Installed a new water pump with proper sealing
Installed a new thermostat
Reassembled components
Refilled coolant with correct mixture
Bled air from the system
Tested for leaks and proper temperature operation
Total time on-site was about 2–3 hours.
Result
After the repair:
Engine temperature stabilized
Cooling system operated efficiently
No signs of leaks
Vehicle ran reliably without overheating
The customer avoided potential engine damage by addressing the issue early.
Why Thermostats & Water Pumps Fail
These components can fail due to:
Heat and age
Internal wear
Coolant system contamination
When they fail, they can cause:
