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.

Stop leak clogs flow thru the heater core radiator etc if both the radiator hoses arent getting really hot your not getting flow thru your radiator. Thats why it ls getting too hot. Also are both your heater hoses going into your firewall getting really hot?Are you sure you got the spark plug wires routed cirrectly when you replaced them?

If you had a blown headgasket you would have steam out the tail pipe and would be loosing coolant. You should still have flow in the cooling system though. What about the heater hoses are they getting really hot?
