The car should be able to at least maintain a steady temperature. The engine operates best at a certain temperature. Above or below that and the engine isn't efficient. Overcooling or overheating isn't good.

Should it be running cooler? I don't know. Cooler than what? Stock? Other brands of radiator?

What temp gauge, OEM or aftermarket? The OEM gauge is very inaccurate, and is only a 3 step sensor, i.e. it will only show low, medium, and high. Anything in between won't show up. So at the medium mark there is a lot of temperature variation.

The SR has 2 engine temperature sensors: one for the gauge and one for the ECU. Which one are you asking about?

They're both clustered around the water inlet on the lower radiator hose and thermostat area. The gauge sensor has 1 wire while the ECU sensor has 2 wires.


This one shows the ECU sensor. The gauge sensor is next to it.
