Did you run the motor KD? There are small passages that the coolant goes through and if there is any debris it may have clogged a passage or two. Flushing the cooling system with the motor running allows more pressure than what the hose can provide to possibly flush sediments or the likes out. Oh and a swollen hose should be changed out if you haven't already bro. Pressure is lost to swollen and soft flexible hoses. Also make sure that when you refill your system to allow the bubbles to escape. That is very important because the bubbles will cause cooling issues, since air doesn't transfer heat as well as coolant or water. Another thing is to keep the resevoir above it's min line. That resevoir keeps air bubbles out by allowing any overflow to escape and then fills the rest of the system of what it is missing...then the cycle continues until there is no longer any overflow.
A vacuum seal is important in this system, so also check your radiator cap or just replace it. Air can enter through there too if the cap's seal is worn out and can no longer keep the seal.
Oh and water alone is fine for troubleshooting purposes, but I don't recommend it alone since it evaporates rather quickly (hence the oily compound in the coolant).

 

Yeah, thank you very much john once again... one thing i noticed is... when i was running the engine capless a lot of bubbles started blowing up after i shoved the hose down the radiator... i waited for a few til all the bubbles were gone.... i refilled the reservoir, sealed the radiator cap as tight as i could and turned the engine again.... now its running trouble free.
Its funny how such lil things can cause such and issue, but im gald is solved now and that i did it by myself with you guys help... im saving up for taiwan and cant really spend on mechanics and stuff like that (thats why i dont mind having a 420a... suppossedly a lil bit more reliable... but how reliable can a 10yr old car be haha).
Tomorrow i am getting some nice antifreeze =)

 

I wonder if there was just a bubble that caused the issue. Bubbles can also cause flow problems. It's very similar to air turbulance on an airfoil where the turbulance causes poor airflow over the airfoil.
Anyhoot, glad you're all good bro!

 

yeah... thnx for the help =) you know... i still have to fix the blinker issue but ill leave that for later lol... im just gonna sleep right now... im tired and pissed as you can see on the other thread lol... and you should too... its late haha
