Is the check engine light on? If so, have you had it scanned for fault codes? When it overheats, have you pulled over and with engine still running, checked that the engine cooling fan is running?

Hi I purchased this car with the check engine light on so it may already have some underlying issues The car drives fine for a while (temperature is normal on dash) then after it's been running for a while it will start not accelerating and the engine temperature climbs without the fan kicking on. After I turn the car off for a while it will drive normally with the fan working when it needs to. It never happens when I first drive the car or if I don't drive it a lot. Is it the fan system or thermostat? Or something else? I recently got a new [radiator](/topics-radiator-chevy/), hose, and I think fan 3 months ago.

HI, The fan turns on due to signals from the computer. The computer gets temperature readings from the engine coolant temperature sensor. So it is possible that engine coolant temperature sensor is not reading correctly. It and the fan both need to be tested to determine which is the cause. Thanks for using Just Answer and letting me help you. I hope I provided what you needed.
