HI....
My 5.7 hemi boils after 3 miles, the coolant is there. Could it be the thermostat?

 

Maybe. Might be a lot of things. But getting that hot after just a few miles.... I would suspect the thermostat simply isn't opening.

 

Hi, let's hope it's just that, because if it's the head gaskets, it makes me want to cry.

 

HI,I did the simplest test: I removed the thermostat and noticed that it was stuck. So I removed the part with the spring and only installed the upper part, where the gasket is. Now the temperature remains at a minimum, I ordered a new thermostat. Luckily, the engine was not damaged. See you soon!!!

 

The most obvious cause seems to be the thermostat — the engine overheated way too quickly. I’ve dealt with this same overheating issue on the car before and managed to fix it temporarily, but it keeps coming back. After trying several times to sort it out, I’ve decided to sell it and go to buy something as-is through the bank seized vehicles auction. I think that buying new car maybe was the best decision that i have managaed to come with.

 

Hi,Luckily, I've solved the problem. My Durango turns 20 this year, and here in Italy, if I wanted to buy a new car, it would be a tragedy. For example, Ford, except for the Mustang, all the rest have a 1000 cc 3-cylinder engine, BMWs and Mercedes, except for the AMG versions, have 2000 cc 4-cylinder engines, and a 2000 cc 4-cylinder Volkswagen Golf GTI costs a whopping 50,000 euros. Given what the sad market holds, I'm holding on to my Hemi.
