Question about 1997 Dodge Caravan

2 Answers

Overheating caravan suddenly overheated. I let it cool, and proceeded straight home, as I drove, the gauge would go up (getting hotter), then would go back to mide range (getting cooler) - Has my thermostat gone bad/or is going bad, or is it possibly my water pump?

Hi,

If it were a defective water pump, the increase in temperature would not go back down to "mid range (getting cooler)", so most likely it is not.

It is most likely a sticking thermostat as that is basically its purpose, to restrict the coolant flow and allow the engine to reach operating temperature thereafter grant free flow of the coolant. It would seem that there is considerable delay in its opening and therefore the temperature rises above the normal operating temperature.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

98 dodge caravan overheating...heater works..checked fans they came on later but when I drove it after it cooled down and it overheated...check engine lite came on.


About the only things are the thermostat and the water pump.There could be something with the radiator but that is the rarest because the water shoots straight through.If it overheats fairly rapid,it's most likely the thermostat.Sometimes a water pump will let you go 20-30 miles before overheat.The thermostat is cheaper and easier if you're going to try it systematically.Overheat will probably cause the check engine light too.Good luck!

1997 Grand Cherokee Laredo, 4WD, 5.2 V8. My Jeep overheated today. When I went to open the hood I could feel steam. So I waited for it to cool before taking the radiator cap off and see no fluid in it....


Have system pressure tested when cold and full to top. Pressure test will force coolant out and you will be able to trace the leaks location. Hopefully it's a small hose leak and not a major problem like a blown head gasket or cracked head.

1995 Mitsubishi Diamante is overheating. Oil pressure light came on - oil was low 2 quarts. Added oil, drove down the street, temp gauge went to Hot. Let car cool down. Drove home, check engine light came...


something is strange here thats for sure ,firstly take thermostat out and put it in a saucepan of water and boil it to see if opens .,check the oil light switch and pull the rubber boot cover back to see if any oil is behind it ??.-You are buying trouble with a car with such a high mileage on it ,never buy anything with more than 50,000 miles or you are just buying someones rubbish

2001 grand caravan overheating. then suddenly cool


Change your thermostat before it sticks closed completely. Sticky thermostat is usually the cause.
Another possibility is that your radiator fan temperature switch is going bad. This is usually located next to the upper radiator hose at the gooseneck on your engine where the thermostat is located.

Engine overheating


is the radiator low on coolant? dont think you have a bad head gasket, does sound more like a bad cooling fan and/or thermostat
