Ford Contour Engine Coolant Thermostat Guide (1995-2000)
Understanding common thermostat failures and choosing the right replacement for your Contour.
- A failing thermostat can cause your Contour to overheat or run too cool, affecting performance and fuel economy.
- For the 2.5L V6, accessing the thermostat is more difficult than on the 2.0L I4.
- Always replace the thermostat gasket, and consider replacing the entire housing assembly to prevent future leaks.
- High-quality aftermarket brands like Gates and Stant are reliable choices for this vehicle.
Is a Failing Thermostat a Problem on the Ford Contour?
Yes, like any car of its age, the 1995-2000 Ford Contour can experience thermostat failure. These failures typically happen in one of two ways: stuck open or stuck closed. A thermostat stuck closed will cause rapid overheating, which can lead to severe engine damage if not addressed immediately. A thermostat stuck open will prevent the engine from reaching its proper operating temperature, leading to poor heater performance, reduced fuel economy, and potentially a check engine light with codes like P0128. Owners in online forums frequently discuss overheating issues, with the thermostat being a primary suspect alongside the water pump and radiator.
Symptoms of a Bad Thermostat in a 1995-2000 Ford Contour
- Engine Overheating: The most serious symptom. If the temperature gauge climbs into the red, or you see steam from the engine, the thermostat may be stuck closed, trapping coolant in the engine.
- Engine Running Too Cool: If the temperature gauge stays low and never reaches the middle "Normal" range, the thermostat is likely stuck open.
- Poor Heater Performance: Lukewarm or cold air from the vents, especially in winter, is a classic sign of a thermostat stuck open, as the coolant isn't getting hot enough.
- Check Engine Light: A thermostat that is stuck open or not regulating temperature correctly can trigger codes like P0125 (Insufficient Coolant Temperature for Closed Loop Fuel Control) or P0128 (Coolant Thermostat Below Thermostat Regulating Temperature).
- Coolant Leaks: While not a direct symptom of the thermostat's valve failing, the plastic thermostat housing on some Contour engines can crack and leak with age.
Important Note for V6 Owners
The 2.5L Duratec V6 engine is known for having a more complex cooling system packed into a tight space. A failing thermostat can be one of several potential issues, including water pumps with plastic impellers that degrade over time and head gasket issues. If you are experiencing overheating, it is critical to diagnose the problem correctly.
Choosing the Right Aftermarket Thermostat
For a vehicle like the 1995-2000 Contour, a quality aftermarket thermostat is often a practical and cost-effective choice compared to tracking down a new OEM part. However, quality can vary. Based on general automotive community feedback, brands can be grouped into tiers.
Brand Quality Tiers
- Premium Aftermarket (Recommended): Brands like Gates and Stant are well-regarded in the automotive community for producing reliable, OE-equivalent parts. Many professional mechanics and experienced DIYers trust these brands. A Ford Contour owner on a forum reported successfully using a Stant thermostat. Motorcraft is Ford's OEM brand and is always a safe bet if available and within budget.
- Standard Aftermarket: Brands like Motorad and Facet offer a balance of affordability and function. Some forum users have reported issues with lower-quality thermostats from various brands, so while they can be a good value, they may carry a slightly higher risk of premature failure compared to premium brands.
- Performance Brands: A brand like Mishimoto produces performance-oriented parts. While high quality, a performance thermostat is generally not necessary for a daily-driven, stock Contour and may be overkill.
Pro Tip: Replace the Housing and Gasket
The thermostat on the Ford Contour is often located within a plastic or aluminum housing. These housings and their gaskets can become brittle and crack over time, leading to coolant leaks. It is highly recommended to replace the thermostat housing (or at least the gasket) at the same time as the thermostat to prevent future leaks. Some aftermarket kits include the thermostat, housing, and gasket as a complete assembly.
Cost of Replacing a Ford Contour Thermostat
| Part / Service | Estimated Cost |
|---|---|
| New Aftermarket Thermostat | $10 - $70 |
| Shop Labor | $100 - $250 |
| Total (DIY) | $10 - $70 |
| Total (Shop) | $110 - $320 |
Cost estimates are approximate and can vary based on your location, the specific brand of part chosen, and your vehicle's engine (2.0L I4 vs. 2.5L V6).
Frequently Asked Questions
Is it hard to replace the thermostat on a 1995-2000 Ford Contour?
The difficulty depends on the engine. On the 2.0L Zetec engine, the thermostat housing is relatively accessible. On the 2.5L Duratec V6, the thermostat is located at the rear of the cylinder head in an inline housing, and accessing it can be more challenging, sometimes requiring the removal of the battery to gain better access.
Should I use an OEM Motorcraft thermostat or an aftermarket one?
For this vehicle, a high-quality aftermarket thermostat from a reputable brand like Stant or Gates is a perfectly acceptable and often more affordable choice. While Motorcraft is the original part, the key is choosing a quality replacement to ensure reliability. Avoid unbranded, no-name parts.
Were there any recalls for the Ford Contour thermostat?
There have been no specific recalls issued by the NHTSA for the engine coolant thermostat on the 1995-2000 Ford Contour. There were recalls for other cooling system components like the fan on some models, but not the thermostat itself.
What temperature thermostat should I use for my Ford Contour?
You should use a thermostat with the original equipment (OE) specified temperature, which is typically 192°F or 195°F for this vehicle. Using a thermostat with a lower temperature rating can negatively affect fuel economy and engine performance, and may keep the check engine light on.
Do I need to bleed the air out of the cooling system after replacing the thermostat?
Yes, absolutely. Air trapped in the cooling system can cause overheating and erratic temperature gauge readings. After refilling the coolant, you must properly bleed the system by running the engine with the heater on and allowing air to escape through the coolant reservoir or a dedicated bleeder valve, if equipped. Some mechanics recommend using a vacuum fill tool for these engines to ensure no air pockets remain.
