My 2003 Chevy Venture loses power while driving, the hot coolant light comes on and the temperature gauge goes all the way to the red mark. There is coolant in the radiator and in the reservior and the engine oil doesn't show any signs of coolant. Just had a oil change a few days ago. Had the radiator flushed a few months ago, the transmission flushed, fuel filter replaced, new plug wires, all within the last 5 months.

Check the thermostat and water pump. Remove the thermostat and see if that corrects the problem. If not, replace the water pump. It's a good idea to replace the thermostat when replacing the water pump, but not 100% must do.

Today my red light came on saying my car was over heating. And my water cooling level was in the red zone,
my over flow jug was full and hot. I cut the car off and let it cool off for 15 minutes and the problem went away,
was that a warning that something was going bad and if so what.

Have the cooling system pressure checked for leaks it may be a head gasket.

If we are to assume the cause is related to falling off the jack, the best suspect would be an inoperative radiator fan. The clue is the engine will not overheat at highway speeds when natural air flow is sufficient. Look for a damaged connector or torn wires.

I have a 2003 Chevy venture 3.4L that is overheating still. I've replaced thermostat twice replaced the water pump replaced the radiator cap and flushed the radiator and done a pressure test but it's still running very hot temp goes up and engine gets extremely hot at first it only got hot once you drove it for a couple miles then stopped say for a train or long light the temp would go up to just before the red line but would cool once you started driving again. Now after replacing everything and flushing the system it gets hot almost instantly after starting the van and my coolant starts to pressurize and come out the radiator cap. I boiled the thermostat and it's working properly at the temp it should function. I took out the thermostat and ran it for a couple miles and it got very hot again so I'm not sure what it could be. There are no signs indicating bad head gasket so I'm clueless here. Any help would be truly appreciated.

You need to leave it idling to find out if the fan comes on before it hits the red zone. The fans are programmed to come on at a very high temp intentionally and many people think there is a problem when there isn't. If it hits the red zone without the fan coming on, then the fan needs to be troubleshooted.

No water leakage, but can't drive car unless temp is turned to hot, can't turn on air at all

Check and make sure your anti freeze is full. Also check and see if your cooling fan is working or not. If it isnt, check your fuses. Let me know what you find

IT is under the throttle body on the driver;s side. IT's a PITA. I don't know your skill level and patience. A novice should set aside 3-4 hours. I think book is around 1.3 hours.

My car was overheating and the red light came on, I let it cool off for a half a hour and I did not have anymore problems
was that a sign that something was going bad. I just let it run a little while ago to see if it would over heat again but it didnt

Is the coolant clean and full? Have you ever replaced the thermostat? Are the cooling fans coming on?

Engine Cooling problem
2003 Chevy Venture 4 cyl Two Wheel Drive Automatic 120k miles

Car overheated, floored all the way to the H. Had towed home. Reserve tank full, radiator empty. No visible leaks. Filled radiator, bled air from hoses, seemed to make a difference. Drove around ok. Drove today to get new radiator cap, 30 minute car trip, overheated again. Reserve tank bubbling. Fans kicking on. What else can be looked at?
