coolant

since im learning about cars, here's a new thing i learnt today. coolant or also known as antifreeze is used to absorb heat from the engine and together with the radiator helps to cool down the engine. so it is made from propylene or ethylene glycol which when combined with water changing the freezing and boiling point thus helping to distribute the heat. there are different types of coolant which will help further change the freezing/boiling point and that will depend on the car and weather of the place but for my place which is constantly hot all the time i wont bother much about the freezing point.

first thing about coolant is that it must be mixed with water 50/50 ratio as coolant itself will not do anything. so note that product bought is already mixed with water or purely coolant that will need to be diluted.

the issue with coolant is that we have to change it after sometimes depending on cars as coolant properties for anti rust deteriorates over time and will need to be replaced with a new one. a coolant that lose its function can lead to rusting and corrosion which will be bad for the engine.

now there are also issu eof low coolant level. basically the radiator will be connected to the coolant reservoir and from there we can check if theres enough coolant. low coolant level will cause your car engine to overheat and lead to more serious damage and in some cases can be irreparable. so yeah check your coolant level from time to time. coolant level become low can be due to evaporation whch is normal but very little as coolant is in a closed system and another thing is due to leak. well we can notiece the leaking if there are drops of fluid from the engine bay  and just pinpoint the where the leaking is. got to fix the leaking then.

i read about coolant as i note theres a coolant warning sign popping up in my car as i drove yesterday. and yeap the level is way below the reservoir. thats not a good thing. upon further inspection i noted that the fans are not working and my brother manage to find that the fuse is burnt out. so yeah the car aircond system is now not functioning, cooling system went busted and coolant level is super low.
i wonder is it because the fan not working leading to overheating of the engine causing the coolant to evaporate faster or its the low level coolant causing the damage ofthe other components. either way ill get these settled in the workshop then. one thing i notice is that theres no leaking there which is a good sign.

oh yeah i used to remember my father just fill in the radiator with tap water as a coolant in his old car. man that thing was rusty inside 100%. if that was in the car mechanic game, i would have change toa  whole new component

oh btw, side note, coolant has a sweet smell (no idea how it smell though) and if theres leaking we should be able to smell it and yeah the sweet smell can attract animals/kids. becareful not to let anything ingest it as it is really poisonous. a small amount is enough to kill a cat or dog......
hey, wait a minute.... i can "accidentally" spill it on the floor to get rid of the cats thats been littering shits infront of my house heheheh
