Hello everyone, i am having a dilemma with my car and after looking at many youtube videos on suspected problems and fixes the one thing keeps coming up about problematic O-Rings in the upper radiator hose and the thermostat T-Connecor pipe. My issue is if i am draining the cooling system on an 85,000mile car is it worth it to just change the o-rings or should i go all out while i have it dis-assembled and change everything in the cooling system. In the fall i had to add about 2 liters of premix anti-freeze and i went to start it the other day and it was at operating temp and the degauss bottle was empty again, as i cannot see anything leaking under the car bot car smell the fragrant aroma of anti-freeze i figure it was probably going to be the o-rings,thermostat,or water pump... i figure why not ask people's opinion as i won't be driving the car till march/april i can get the work done and pray....i am not one for doing a job half ways when i can get it done and not have to worry about it again the only thing i didn't price was heater hoses every thing else come in at under 600 dollars.. also if anyone has a copy of a repair manual for this car let me know where you got it as i can only find one that's online
