Check your coolant level and keep an eye on your temperature gauge. A car will run fine with an overheating engine right up to the point when the engine seizes.


This is your Heater Control Valve But I am going to explain what it does. First of all the "wire" you see is actually a vacuum line, it's a hollow (hopefully) air-tight tube that passes vacuum to the Heater Control Valve. The heater control valve is a vacuum actuated valve that in the open position allows fluid to pass through and in the closed position ...


Yes, it's normal. Maybe just a tiny bit on the cool side. But if you're in traffic a lot that cooler thermostat is a good thing. All the cars I've owned would run between 85 and 95 degrees Celsius. 85 at highway speeds, then creeping up to 95 or 96 when in slow traffic, at which point the fans kick in. Pro tip: the hotter an engine runs, the more ...


In terms of possible root causes for failure, the following scenarios are likely culprits for a cooling system to run too cool: A temperature sensor that's reporting lower-than-actual temperatures due to issues like drift/fouling/calibration. A sticking thermostat that is flowing more coolant than necessary to maintain 176 °F. Really cold ambient air ...
