Or just do something to patch? I gg to buy some distilled water and pour in first later today. I had to change my whole radiator. Which is why I always ask this standard question. I recall got others having the similar issue. Actually, changing of the radiator coolant requires a flush to get everything out. I came to know because I brought X bottles of distilled water (as per the owners manual) to the workshop but they did not use everything. When changing to my present vehicle, I asked the SE what coolant was use. Mine now uses premix which I feel is less of a hassle even if you have left over coolant while changing.

Yeobh 4th Gear February 19, 2021 Share February 19, 2021 Basically there re two types of coolant - Ethylene Glycol ( use mainly by Asia Cars ) & Propylene Glycol ( use mainly by European Cars) . Premix coolant has ratio of 50 :50 glycol to distilled water. Tap water should be avoided as is often treated with chlorine, which is corrosive. For cooling system leak, go to shop that has coolant pressure tester for diagnosis. One of the best method to determine if the coolant is properly mixed is to measure the strength or concentration of the antifreeze ( glycol ) with a hydrometer. 1 Link to post Share on other sites More sharing options...
