The first place I would check would be to make sure the electric fans are running.

My chana 1.0 panel van switches off while driving when hot, drives fine when cold, until fan kicks in

My 01 Pontiac Montana is trying to overheat at high power

If your vehicle doesn't actually overheat, just getting hot, I think that's the normal behaviour for these cars. My 03 AWD behaves the same way. When driving uphill, especialy when towing, the temperature rises close to the red marking, but I have never experienced it overheating. I think that the temperature has to rise much over the normal driving temperature to activate the two electric fans.

94 Econoline Van Overheats when under load but drives fine when it's not.

Radiator could be blocked or partial. Best way I check for that is to use a temp laser gun and check the fins of the radiator for temp differences. And has stop leak ever been used?

Hi, you need to firstly replace the fuel filter, the problem is the idle solenoid in the pump has dirt in the piston! From the passenger side of the engine remove the solenoid at the back of the fuel pump 2x 5mm Alan bolts, there is 2 solenoids in the pump the one closest to the block is fuel temp. After the idle solenoid is removed, in the solenoid is a piston held in place by a circlip and there is also a spring in there, clean out all dirt inside and reassemble replace both o'rings and reinstall your problem will be solved. I have just fixed one 2 days ago.

Ac works at beltway speed but not nieborhood speed

Sounds like your fan is not coming on. You will need to find out why.
Over heating your engine is never good.

I have a 91 Dodge Caravan LE 3.3 liter V6 engine, The long story on what problems I have had with this car is as follows. The first thing that happened was I had a fusable ling burn out on the van, this I...

For first check the coolant level.If its low then it must be made full.If its full then check out for any kind of coolant leak.If the coolant is low or getting leaked from somewhere then the car will overheat.So get the ac pressure test done.At any local car garage they do ac pressure test.Doing this test will let you know that there is coolant leak or not.If there is coolant leak then that leak is the cause of overheat.But if there is no coolant leak and coolant level is also full.Then ignore coolant cause for overheat.Then other cause may be the thermostat ,thermostat allows coolant to circulate when the engine is warmed up and should be closed when the engine is cold so that the car can warm up faster. It's a fairly inexpensive part that's replaced easily, but when it fails, your car can overheat, causing costly engine damage.
To check if thermostat is faulty try this procedure:--
Warm up the car but don't let it overheat--don't let the thermostat gauge go into the red.Turn off the engine.Open the hood.Find the upper radiator hose. It's black, is made of rubber and is about 2 inches in diameter, with metal clamps on either end. The upper hose goes into the top of the radiator.Locate the lower radiator hose. It looks similar to the upper hose except that it attaches to the bottom part of the radiator.Touch each hose very carefully (they can be extremely hot). If the temperature gauge is indicating that the engine is warmed up but one hose is hot and the other is cold, the thermostat is probably stuck closed, and the coolant isn't circulating through the radiator.the thermostat is faulty is the case. If the thermostat checks out ok then it can be faulty temp sensor.Its also called coolant temperature sensor. The coolant temperature sensor is a thermistor ( a resistor which varies the value of its voltage output in accordance with temperature changes. ). The change in the resistance values will directly affect the voltage signal from the water thermosensor. As the sensor temperature decreases, the resistance values will increase. As the sensor temperature increases, the resistance values will decrease.
The coolant temperature sensor lets the engine control computer know what the engine temperature is by gathering information from the engine coolant temperature.
There are several ways to know if the coolant temperature sensor is malfunctioning, if the sensor is bad it will trigger a trouble code and the check engine light in the dashboard will come on, you can retrieve the engine code and see if it is related to the coolant temperature sensor, even if the engine control computer doesn't store a trouble code, there is another way to suspect a bad coolant temperature sensor : If your vehicle starts using more fuel than usual, starts having trouble starting when the engine reaches normal operating temperature or you notice black smoke coming out from the exhaust tail pipe, it is very likely that these symptoms are related to a bad coolant temperature sensor. A thermostat that is stuck closed will cause the engine to overheat. To test if thermostat is stuck in the closed position, place the thermostat in boiling water. If the thermostat doesn’t open, than the thermostat is defective and needs to be replaced.
Check the Engine Coolant Fan
Since the cooling fan pushes air through the radiator to cool the coolant, a fan that’s not working properly will cause an overheat condition.
  1. Electric Fan – If the vehicle is equipped with an electric cooling fan, check to see if the fan is working properly. Most electric fans will only operate when the coolant temperature reaches a certain degree. In many vehicles when the air conditioner is turned on, the electric fan automatically turns on. The most common cause of an electric fan failure is the fan motor, a controller module or a relay.
  2. Engine Driven Fans – Some vehicle have cooling fan driven off the front of the engine. If the clutch (between the fan and the engine) is bad it may slip. If the clutch slips it may not allow enough rotation on the fan to be affective and the clutch needs to be replaced.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

oddly enough it sounds like a transmission problem, get a transmission shop to assess the problem, but first try replacing the thermostat. be sure to turn on the heater when adding antifreeze. I have had this problem with my windstar.

Pt overheating within 5 minutes

first If the fans arent coming on, thats where we re gonna start. Make sure the radiator and reservoirs are full,If they come on when the ac is on, turn the ac on and drive it. Does it still overheat? Yes or no. Yes? need more info. No? We need to check fuses and temp sensor. Keep in touch. I ll help you best I can from here.
