I must have missed the part in your post about it burbling out of the overflow. Is it overheating when it's doing that? It can overheat due to no circulation.
It could be the headgaskets for the burbling, but on these motors we usually get smoke out of the exhaust or milky oil too. Have you done a pressure test on the cooling system when its hot?
Have you ran the vehicle hot before?
If you get a chance check for circulation on the coolant hose going from the intake to the overflow just for S and G's.
Yeah, after my uncle tried burping it again the other day it was pushing it's coolant out the reservoir tank with the lid off.
It hasn't been ran hot, it has never overheated since we've owned it anyway (nearly 100,000 miles and 2 years).
I just don't understand how it got like this. After the heater core replacement the heater worked just fine. Even when the heater core was leaking it was still blowing heat. I drove it a couple weeks after the heater core was replaced and that's when the radiator started leaking. The heater worked as long as the coolant level was up... I kept a jug with me and kept adding coolant to it everyday. The temp. gauge in this car is a joke, nothing more than an idiot light, but it never went above the middle of the guage.
Finally the new radiator came in and I dropped the car off for it to be replaced. My uncle said the heater was working once he got it all back together. I picked up the car and began to freeze to death.
I'm not familiar with how to do a pressure test on the cooling system, got some tips?
Also, when we first got the car, we did have to have the cooling system flushed a few times.. It was so gunked up back then and the symptom of that was the heater not working.
I'm wondering if it's something as simple as a restrictor in a hose being left out. I don't know if there is one in these cars.
This is very frustrating for me. I don't know whether to junk the car or start throwing even more money at it. Opening this engine up seems like it's going to be a big can of worms. If there's THAT much corrosion inside the cooling system, what other problems are we going to run into as hoses and parts start coming off...
