Van overheating

The van will overheat at Idle, at a stop the fan will not come on. The fan does come on if the air conditioner is on. I have replaced temp sensor, ran resistor, relays, fuses. When it overheats the reservoir will start popping and shaking.

Engine Cooling problem
2003 Dodge Caravan 6 cyl Automatic 150941 miles

My car began to overheat about 8-9 months back. We had a leak in the water pump. We replaced the water pump and belt. After that heater would not work right. It would be hot and then it would get cold and our van would start to over heat. It appeared that this would occur when I would stop the vehicle. We had someone remove air from the lines. This temporary fixed the problem however after about a week the problem came back. Not long after we changed the thermostat and the weather changed. I did not seem to have any problems for a couple of months. Then my van began to overheat again. We flushed out the radiator and bought a new cap. This seemed to help the problem some however my radiator would still lose coolant. I could drive it without it over heating but it was still losing coolant for atleast a 40 minute distance however before I would get in my car to go again I would refill the radiator with 50/50 before driving it again. I would be short about 1 gallon. When we took it to the shop to be fixed they said they thought it was the water pump and while they were replacing that they would also replace the thermostat. I told them it wasn't long ago that we replaced both of those things. The man said it could have been a faulty water pump since we have had problems on and off since we replaced the last water pump. He said he did not see any signs that it could be a head gasket. Since the vehicle was not overheating at the time he wanted us to bring it back when it was overheating to be sure. I noticed that morning I had coolant under my van where the water pump is so I brought it back and gave him the okay to replace the water pump and thermostat. He did and as soon as I pulled out of the shop it began to overheat worse than it ever has. In the past when the vehicle was over heating it never reached the H on the meter. We turned around and brought it right back they said they believed it was a clog in the radiator so they replaced the radiator. When we left the shop the car did great for about 10 miles. It slowly went up on the overheat meter until it got to the half way point. It stayed at the halfway point for a few seconds and then it shot quickly up to H and the overheating light came on. This has never happened before. I pulled off the side of the road and noticed that my coolant was boiling out of the overflow tank (this has also never happened before). My radiator is down about a gallon of 50/50 again and the problem is still not fixed and appears worse than ever. Do you have any ideas that can help me. The people at the place we were getting it fixed do not ever seem sure of the solutions to fixing out vehicle. They told me that fixing the water pump and thermostat was not guarenteed to fix the problem. While they appeared sure of replacing the radiator it did not fix the problem and now my vehicle is worse off than before. Other than the overheating problem it runs fine. No white smoke coming from the exhaust. The heater is still not working right. When the vehicle was overheating I turned it on to pull the heat from the engine and it was blowing cold air. Thre is also a spot on my floor that gets wet when I run the heater. Other than that I can not thing of any other problems.

95 Dodge Caravan, 3.0 L V-6, Auto, 2-W Drive, 150k with no serious problems suddenly overheats. Then noticed that it maintains a constant normal temperature while idle but increasing RPMs causes temperature to spike to overheat range. Is this a radiator problem?

Try replacing the thermostat then flush the coolant system hopefully that will work.

I have a 1994 Dodge Caravan 6 cylinder 3.0 with 84,213 miles. Three days ago it started overheating so I changed the thermostat and it still overheated so I tried flushing the radiator and it still overheats. I checked the oil dipstick and the exhaust for water and I don't see any so I ruled out the head gasket. Does that mean its my water pump? The water pump was just replaced in January of 2002 before I moved from Michigan to California. Could it go bad again in just four years?

Van has had water pump. Thermostat, tune-up, radiator. Hoses. Cooling temp sensor new fluid, all done in last two weeks. Now its overheating again with no smoke. But can hear bubbling behind driverside dash almost as soon as car is cranked. And heater will blow for a awhile then it goes cold an car overheats. Steam comes from overflow an it bubbles. What now?

My engine overheated & water is coming from the engine

I am not very good at this - but my engine (as I have been told)is side mounted under the dash. The water was coming from the driver side of the engine. I was told to buy Blue devil, I followed the directions on the bottle & after a while having the engine run, out came the water again from the same area.

I have replaced the thermostat today, waterpump 6 months ago, top radiator hose swells up, antifreez gos into resevoir tank, if you gun the engine it flows sometimes, heater hoses are not getting flow either, is it the water pump? You get heat for a second if u gun the engine, then the hose feels normal, then same issues start again, how can I tell also if the radiator is clogged or has a air pocket, no heat when hose is swelled up, does it sound like the waterpump, obviousl also coolant loss from this would cause no heat, help, I have been working on cars all my life

I recently sent you an email about our Dodge Caravan 1990 3.3 L I forgot to mention after the repairs are made we have been running straight water, that would cause it to over heat fast right
