Which is best coolant for mehran and other small cars

[Xulfiqar]

xulfiqar bhai, actually i have tried number of coolants, when my radiator got leaked, the mechanic adviced me not to pour the coolant again, because the coolant is having chemicals and they are not good for radiators

your mechanic is a moron.

the "chemicals" in coolant are for protection against rust and corrossion. The really oldschool coolants and the caltex version of the GM coolant are very effective de-rusters too - but you cannot find them in Pakistan now.

The modern coolants are HOAT coolants which are excellent in their job.

What you experienced is the blowout of some hole that was blocked by rust or something. In my opinion you should be thankful that it happened there and not on a highway when the vehicle would be doing high rpm and speed.

Mechanic dont know about coolant i think..It is better you go for only Nasa brand super coolant which is the best and more economical in prices and its ready to use..further do not use concentrated coolant like caltex or any other costly brand as it is concentrated and as per international recomandation never use concentrated coolant.if you use concentrated coolant you have to mix water to dikute it.The use of water is strictly prohibited to use in the radiator as it has minerals and salts which causes rust and corrosion.so in coolant only demineralized water should be use which is free from any mineral or salt. and we normally cant get demineralized water from the market to dilute in concentrated coolant.The Nasa coolant is cost around 170 per lit.
i have also tried osaka and vislee coolant which is purly a tap water with mixing of green colour.so pls refrain from such type of cheap coolant which are only minting money.

Sorry Xulfiqar bhai its an old thread but related to my problem. Xulfiqar bhai can I use this Fuchs coolant (premixed 40% con) in my Mercedec w210 E240 2001 model. I don't find Zerex 05/48 anywhere in Pakistan. Genuine Mercedes is also rare here.

Thanks

Guard Coolant of red colour is best for mehran.Actually its Ethyl Glycol which is active substance in any Coolant.If after this coolant your car still got warm you need to change your radiator.Lords Radiator is OEM one however you can use other Aluminum Radiator.Never use copper radiator as it turn cool very late than Aluminum.

Guard Coolant is for is 300/Liter and total coolant is 700/Liter.They are more good than other so called imported coolant as they are not made for such environment.
