Question about 2003 Dodge Durango

1 Answer

Cooling Problem I have a 2003 Dodge Durango with a 4.7L V-8. It is overheating. It was pegging the temperature gauge so I replaced the thermostat and while I was at it I discovered a bad radiator cap. After I replaced these, the truck was running cooler and the gauge was slightly under the halfway point. Now it's starting to get hot again. For starters, I'm losing coolant somewhere. There are no visible leaks under the truck and I never smell antifreeze while driving. I thought maybe I had a leak that was happening at speed so I put Bars Leak in, put a considerable amount of coolant in and followed the instructions. I cranked the heater up and went for a drive. Well, it still overheats. What I found strange is that when I hit a stoplight the temperature gauge starts climbing and the heater blows ice cold. When I take of and drive, the temperature gauge drops back to normal and the heater roasts me right out of there. So what gives? This is an area I've never had to deal with.

Check your head gasket

Posted on Mar 24, 2014

Testimonial: "I thought about that. I checked the oil and there's no vapor coming out of the tailpipe. You still think it might be a head gasket? Would a compression test reveal this, how do you know which side? If I do in fact need that fixed, what am I looking at in cost at a shop?"

What can cause a 2000 Dodge Durango 5.9L to overheat while sitting at a stop light? The temp gauge can peg to the right, but the motor does not show any other signs of overheating.

If it is pegged in the red and the engine isn't tapping like crazy or knocking. Want to die. Then it is the temp sensor or the gauge that is bad. A scanner will tell you.

My 2003 dodge durango keeps overheating , i just had new radiator put in and it started overheating again but now it is overheating with a very loud screeching noise like a belt sound what could be ca

as for noise will have to inspect under hood,could be fan or belt or pulley ,water pump .these are some things it could...My suggestion for overheating is replace thermostat. If your car has electric cooling fan then it may not be working..turn defrost on and if fan kicks on then fan motor is good..Now this does not mean that fan is working properly because fan is controlled by heat sensor switch that kicks fan on when motor reaches heat range......Things i would have checked....hope this information helps and good luck and Please rate my post...

2003 durango over heats at idle but temperature cools once moving. Is this my thermostat?

No it is not you're thermostat. You're cooling fan is not functioning. Most likely you will need to replace the fan clutch.

Overheating 2003 dodge durango. What could be the problem??

When engine running, ensure no engine combustion gas bubbles in coolant resevoir (if so, the head gasket is blown).

Check cooling fans are operating ok (when required when car warms up), if not check
1) fuse,
2) relay operation,
3) heat sensor switch.

Replace thermostat.
When re-filling cooling system, bleed off any airlock as necessary.

Check for collapsing (soft) coolant hose on suction side of waterpump when engine revs above idle.

2003 dodge durango overheating

I would have the cooling system serviced, complete backflush...the radiator could be so corroded it's beyond flushing and needs to rodded out or replaced... check the fan clutch for proper operation. Check the exhaust system...a plugged converter will create to much backpressure and cause over heating.
Too many overheats and your looking at potenial engine damage.
Good luck...i hope this helps, please rate me a fixya.

Overheating. the reserve tank keeps boiling over.

Check to see if the cooling fan on the radiator comes on after the engine warms up. If so then try replaceing the thermostat. If not than it might be the temperature sensor that controls the fan.

1999 Dodge Durango NO HEAT

Bad NEW thermostat? I had the same problem on my first generation Dakota. The problem for me turned out to be the DODGE thermostat I used to replace the old Dodge part. I went and got a Stant from local auto parts store using the standard temperature spec and quit shivering the next time I drove it. I hope that helps!

The dodge durango thermostat called for by the dealer is at the temperature of 192 you can solve this problem very simply by instaling a 160 thermostat that can be obtained at any parts store

Electrical cooling fans not coming on due to bad sensor, fan relay, or bad fans. Check thermostat and coolant temperature, too....accordianman
