Asslam u Allikum,
Dear currently 1 coolant use kar raha hu sjo mere father Badami bagh se khareed kar laye the wo koi japanese company h TCL naam ki us ko russia ne khareed liya hua h aur ab wo sirf anti-freeze coolant bana raha hain . mere pas itefaqan 4 bottles pari hui thien jin mei se 2 apni gari mei daal di hain aur 2 father ki gari mein
wo taqreban 750 ka 500cc (almost 500ml shayad) mila tha total 2 liter = > 3000. is k alaw aap guard liquimoly ya caltex koi bhi acha coolant use kar lo
lakin pyro ya aam local products par na jana because colour mix h pani ka boiling point nahi barhata aam coolant.
Steps to change (That's how i am doing in my cars):
1: check water level
2: pour fresh water and fill it.
3: close radiator cap.
4: run it around 1 km.
5: Let car cold enough
5: Park on stand / jack the car
6: open drain plug.
7: drain water
8: Enter more water and start it.
9: remain continous flow of water while starting for 10 mins
10: if you wish then you can insert drain plug while flush.
11: Rotate water (if you are using drain plug to close flow and rotating water then open it after some time and let cool down, other wise just make thick you drain plug through thread).
12: After flushing, insert drain plug with thread tickness on it.
13: Just make sure that you insert drain plug correctly and there is no leakage in radiator otherwise your coolant will waste.
14: Additional step to check, after flushing radiator, put your drain plug in radiator and fill water, turn enigne on, lets check if heating gauge is going crazy then something is terribly wrong otherwise throughly check leakage.
15: If there is no leakage then pull out your drain plug, flush water, put drain plug again with new thread thickness.
16: Pour coolant with water (I put around 1.5 litre coolant normally and remaining is tap water )
17: Try not to fill only with coolant , including water is good because our cars are old enough so pipes are not in ideal condition. Pipe damage occurs if radiator is full of only coolant
18: Enjoy Ride, but concentrate on temp gauge, needle between 0 to mid is normal
