2001 Buick lesabre over heating
I did a oil change spark plugs and replaces heater
elbows ran good for a day the next day the car ran
hot 5 times on my way home I put water in the
reserve tank once I got home I put water in the
radiator ran the car with the AC on in park for about
15 to 20 minutes and the temp hand started rising
again got about 150k miles on it what's the
problem and is it a cheap fix or should I get rid of
the car
