Overheating

I own an intrepid 98 2.7, 115 K, and the last year I got problems because the car overheated, so I had to change the fans, with the assambley, and the radiator. It was like 8 months ago actually.

so now like a week ago my car started leaking the coolant, but I didnt noticed it cuz it was just a little bit, then one day I was getting home when a bounch of smoke was coming out of the hood, and I found out that the water outlet exploted, and the car was overheated, like in the 80% of the gauges, so I took it to the dealer and they replaced it.

but now when I run in the streets its ok, but I i get to the highway and I run faster, like 65-70 miles, the car heats up.

whats wrong with it? I was thinking about the radiator, and I still have the 1 year dealer warranty on it.

Try replacing the thermostat-not it do the following below:

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, loose belt, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump. Also pressure test the radiator cap.
