I changed the radiator recently (just as a precautionary measure) coz water level was reducing in my radiator for a year now, tough no heating issues at all ALHAMD U LILLAH.
Car is margallah G13B.
Installed a Japanese replacement radiator and filled it with water just to verify that there was no reduction in water level.
After repeated checking i have seen that the water level drops (next morning) about 2 inches whenever i top it up in the radiator, however no reduction in the resevoir bottle.
Also there is no further reduction in the water level. i have stopped topping it up. no heating issue or any thing.
please confirm that its the normal water level in the radiator? Also the cap of my new radiator is with steam removal button.
i intend to change the water with a coolent in this week. probably will be shifting to either toyota or zic coolant. I believe suzuki oem coolant is no good.
please confirm regarding lower water level in the radiator consistently (with or without topping it up).
Also the color of water in the new radiator has changed a bit to brownish but not too rusty tough. I have been running the new radiator with tap water for a month now.
urgent help would be helpful.
