Yes, Ihave to believe you have a head or gasket problem especially if you're blowing hoses. A normal cooling system runs around 12 to 14lbs pressure, but a compression leak can boost it up to 100lbs or more.

Thanks James. As a mechanic, what do you suppose the final cost would be to replace head gasket on Durango?

How much $ is always a toughy. Flat rate shows 8 to 10 hours for doing both sides. Not knowing what took the gasket out or cracked the head, I can only guess, but it would be foolish to do only one side. To do only one side shows a labor reduction of only 1 1/2 hours. Parts would be a "headset" which is all the gaskets for the top end of the motor, about $100. If one of the heads is cracked, you'll need a replacement. Used would be about $75-$100. Labor is the biggie, and that depends on where you take it, and how hungry they are. Dealerships are never hungry. I would highly recommend shopping around, get recommendations for other people about a good shop. You can tell which cylinder(s) are leaking by letting it sit overnight. The next day, disable the ignition so it doesn't start and crank the motor a few times then pull the plugs. You should see coolant on the plug tips. Hope this has helped.

Scan for codes and check fuel pressure with a gauge auto parts rent it. We need to know the code due to check engine light. see link for fuel pressure, also try a security system reset. See links.

Hi SAMANTHA HINOJOSA,

If you decide you would like to conduct the scan yourself here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

I have a question I started looking at my truck. The box where my fuses are and relays. Well my vehicle is missing the radiator fan relay and it is missing transmission relay and my 02 number two relay. Is that a bad thing or what do the relays do?

Also, I can get it to start but drive not even a mile and when I stop at a stop sign and press the gas to go it shuts off.

The relays transfer power to the fans and transmission as well as O2 sensor. Does this truck shift at all? If the transmission relay is missing there is no power going to the transmission solenoid unless the person who owned it previously put the wrong transmission in and removed the relay so it would work. If the radiator fan relay is missing the fan will not work the truck will certainly run hot if not working or it was removed because fan is bad so it will not go on. I do not see a relay for O2 but a fuse which should be replaced. From your description I would have a mechanic seriously look at this vehicle see if the correct parts are in it and it may cure your overheating as well as some drive-ability issues. Also, if truck seems to run okay then clean throttle plate on both sides and IAC hole with choke cleaner that may stop the stalling at a stop sign.

My suv is slowly overheating. I went to pulled over and it cooled down quickly. There are no visible leaks that I can see. Could it be my thermostat needing to be replaced? Please get back to me with a response. Im in need of an answer. What else could it be if not the thermostat? Thank you for your response

I have a 2000 Dodge Durango and it overheats all the time. Changed everything I can think of radiator, hoses, water pump, power steering and then some. Please tell me what is wrong.

It also miss fires cylinder three and five all the time. Please help me solve this problem. We have changed it all and spark plugs about eight times already and have only had the car for about two years now.

I use the vehicle for a mail route. The heat hasn't been working (Blow outside temperature air). It's been overheating during the stop and go, but not on straight drives. I've replaced the thermostat, clutch fan, and water pump. What next?
