Have a question about my Chevy?

You mention it has an electric fan - but does it turn on? Perhaps the thermostat that controls it is not working, or the fan itself is not? When you are on the move the fan usually will stay off because the movement of the vehicle causes airflow through the radiator, but that fan should be running once you stop.

You should bring it to a qualified mechanic. Since you mentioned that you have a V4 (which you don't it's an inline four or a V6) you obviously are not experienced with car mechanics - take it to someone who is. If you overheat you risk blowing your head gasket, that will be a much bigger bill.

That's not a V4. A 4 cylinder motor is a straight 4. Check the coolant level in the radiator and if it's ok replace the thermostat. You may just want to get a mechanic before you ruin the head gaskets.

Just depends on how high it climbs. Some older cars usually tend to climb a little as age sets in & it seems anytime it had a major coolant issue in the past also seems to cause the temp to ride at idle. I would check coolany fans to make sure they are operating as intended. Thermostat generally sticks open which can cause a car to run warmer even though it is rare but it all depends on how high the temp goes

Sounds like the classic symptoms of a non-properly functioning cooling fan. A car will have a natural intake of air when driving but not receive that intake of air when at idle or at slower speeds.

As long as it does not overheat this is fine. Driving has airflow through the radiator where as stopped the airflow stops.

Do you have an electric fan?

They only start when needed.

May not have a problem at all as the electric fans don t come on until a fairly high temperature.

First best answer to g - the fan is not working, almost certainly. Not the thermostat, which would affect it at cruise as well as at idle.

Check the engine cooling Fan.

Don't let it overheat get it checked out.
