Removed the thermostat and drove for 30 minutes with the air on and the highest temp reading on the gauge was about 3/4 up. It usually runs at about the halfway mark.

THE DONATION THING IS NOT A MUST---BUT IS APPRECIATED

WE ANSWER LOTS AND LOTS OF FREE QUESTIONS

WHILE YOUR RIG SEEMINGLY WAS RUNNING HOT, WERE THE COOLING FANS RUNNING?

THERE ARE MANY THINGS THAT MIGHT MAKE IT RUN HOT.....EVEN FIVE MINUTES AFTER LEAVING THE FACTORY SOMETHING COULD HAPPEN! SO LET'S NOT GET LOCKED INTO THINKING THAT THINGS SHOULD ALWAYS BE PERFECT BECAUSE IT WAS JUST LOOKED AT.....THIS IS A MACHINE, BUILT AND SERVICED BY IMPERFECT HUMANS.

THIS IS WHAT I'D DO 1ST

LOOK FOR LEAKS FROM THE COOLING SYSTEM....COLD

REFILL THE SYSTEM---NOTE HOW MUCH IT TAKES TO DO SO

CRANK AND GET TO OPERATING TEMP....LOOK FOR LEAKING

PAY SPECIAL ATTENTION TO WHEN THE FANS COME ON.....TIME WISE AND TEMPERATURE WISE____________THIS COULD BE AS SIMPLE AS A COOLING FAN RELAY NEEDING TO BE REPLACED

THERE ARE OTHER POSSIBILITIES....I FIGURE WE WILL CHECK EZ STUFF 1ST, BEFORE MOVING ON INTO EXPLORATORY SURGERY

IF IT STARTS OVERHEATING---TURN IT OFF---RUNNING THE ENGINE IN AN OVERHEATED STATE CAN DAMAGE THE HEADS, BLOW THE HEAD GASKET, AND MORE.....HOPEFULLY THIS HAS NOT ALREADY HAPPENED

RETURN WITH ANSWERS, I MAY CAN AID YOU WITH DIAGRAMS ON THINGS TO CHECK, OR WHERE STUFF IS LOCATED

I SLING THIS LINK OUT TO FOLKS, THIS COULD SAVE YOU SOME $$$ AND AID YOU I DIY

My 99 Dodge Grand Caravan keeps overheating. I have replaced the cap, put in new antifreeze fluid and checked for leaks at the hoses. There is no visible water on the ground but I have to keep refilling the resevior and when there is water in it it boils.

Did you replace the thermostat? With all the overheating. Get a leak down test to confirm no head gasket issue

I got a van ONE month ago, and today, it's OVERHEATING. The battery light came on, and the power steering went out right in the middle of driving it. I checked all my fluids, power steering fluid and antifreeze was low, so I filled them. STILL same problems, don't know what could be wrong. It only has 20,000 miles on it.

#1. Over heating - try and replace your radiator cap if that dosen't help try to locate a leak.

#2. Power steering - you need a new power steering pump or belt.

#3. Battery light - it comes on after a wile of driving but will go off later down the road. But if it doesn't get your altinator checked.

Why is my 1999 Dodge Caravan, 130,000 miles, overheating while it is idle? When it is moving the temperature is fine, but if I stop moving and leave the engine running it starts running hot.

Check and make sure the fan is cutting on. Also the water pump might not be circulating the coolant.

Engine Cooling problem
1999 Dodge Caravan 6 cyl 172000 miles

My 1999 Grand Caravan's temp gauge has gone to the "hot" reading. I have turned off the AC, turned the heat on all the way and then the gauge goes back to the center. If I don't keep the heat on after that it goes back to "hot". Could it be the thermometer, water pump or something else?

Have you ever tried adding an air/gas vent to relieve exhaust in the cooling system Due to a blown head gasket?

No, the only way to correct it is to remove the heads and do the job properly.

Why does my 99 Dodge Grand Caravan SE's temp gauge goes up real high then drops back down and makes a clicking noise? And the fan runs constantly while the van is on.
