I am having the same problem. I replaced the intake gaskets and t stat and have had the "low coolant" light on and it is now overheating on a regular basis. If i bleed the coolant and doo all the reccomended things it is fine for 10 miles or so and them redlines and pukes all the coolant outof the overflow. I have a new radiator cap and it made no difference.
Im ready to burn the car down. Any solutions?
