Your vehicle’s cooling system is one of the unsung heroes under the hood. Two key parts, your water pump and thermostat, work together to keep your engine from overheating or overcooling. At Duxler Libertyville Tire, our ASE certified technicians perform expert diagnostics and replacement services for these critical components, helping Libertyville drivers stay safe and reliable on the road.

How the Water Pump & Thermostat Function Together

What the Water Pump Does

The water pump circulates coolant (a mix of antifreeze and water) through the engine and radiator. By pushing coolant throughout the system, it transfers excess heat away from the engine block and prevents overheating.

What the Thermostat Does

The thermostat acts as a gatekeeper: it remains closed when the engine is cold, allowing the engine to warm quickly, and then opens at the correct temperature to permit coolant flow to the radiator. If it fails (stuck open or closed), engine temperature regulation breaks down.

Because these two parts are tightly linked in coolant flow, one failing often affects the other. That’s why many technicians recommend evaluating and, if necessary, replacing both during a cooling system service.

Common Symptoms of Water Pump or Thermostat Failure

If your car is showing signs like the ones below, it’s time to call in the pros at Duxler Libertyville Tire for a cooling system check:

Water Pump Symptoms

• Coolant leaking underneath or around the front of the engine
  
  
• The engine runs hotter than normal or overheats
  
  
• A whining or grinding noise coming from the front of the engine
  
  
• Steam or visible vapor from under the hood
  
  

Thermostat Symptoms

• The engine temperature fluctuates or never reaches its optimal range
  
  
• Overheating on shorter drives
  
  
• Cabin heater fails to warm up
  
  
• Poor coolant circulation or sluggish temperature response
  
  

If untreated, failures in either part may lead to costly damage like blown head gaskets or warped engine components.

Why It Makes Sense to Replace Both Together

• System compatibility: Fresh parts work more harmoniously together, reducing chances of subsequent failure.
  
  
• Comprehensive reliability: Since accessing one often reveals or gives partial access to the other, doing both ensures complete system health.
  
  
• Full system inspection benefit: When replacing either part, we also inspect hoses, belts, clamps, radiator, and related components to spot hidden wear or potential issues.
  
  

What Happens During the Service at Duxler Libertyville Tire

When you bring your vehicle in for water pump or thermostat service, here’s the process we follow:

1. Diagnostic evaluation
   We test coolant behavior, pressure, temperature response, and look for leaks or inconsistencies.
   
   
2. Removal of old components
   Our technicians remove required belts, hoses, covers, and access the water pump and thermostat housing.
   
   
3. Installation of new parts
   We install new water pumps and thermostats (with quality replacements), along with new gaskets, seals, and fresh coolant.
   
   
4. Bleeding & pressure testing
   We remove air from the cooling system, ensure proper coolant flow, and pressure-check for leaks.
   
   
5. Operational verification
   After reassembly, we monitor engine temperature, check for abnormal readings, and ensure everything runs smoothly.
   
   

As part of the service, we also examine associated parts such as hoses, belts, radiator, clamps, and recommend any replacements needed to prevent future failures.
