I have this for a long time

very useful during covid, as I didn't meet the vaccination requirement, I was not allowed to enter malls and barber shops

I used it to cut botak during covid

and cut my son botak before and during his NS

for my monthly haircut, I just pay $12 lah, looks nicer than botak 😅

This brand good stuff. Bought in 2016 from Amazon. Still working well. Rechargeable one.

In fact coolant itself has got no cooling capability, meaning it does it cool down the engine faster than just pure water,  it is antifreeze which is not needed for our weather and antirust agent which will help to prevent corrosion and clogging of the cooling system.

Yessi...also water has that 100 and 0 for boiling and freezing limit...while gylco based coolant has higher and lower figures than water...plus the antirust capability...if car near scrap...lonkang or rain water also can lah✌️😁

also lubricating the seal of the water pump

my wife's car has many many water pumps

at least 7 the last time I count 😵‍💫

Glycol is not just a anti freeze agent, it has more functions if it is mix in correct portion.

A simple search with AI :-

-------------------------------------

The primary character of glycol in a coolant system is its ability to lower the freezing point and raise the boiling point of water, preventing system failure in extreme temperatures. 

When mixed with water, glycol acts as a highly effective heat-transfer fluid that protects automotive engines and industrial HVAC hardware from freezing, boiling, and corrosion. 

Key Characteristics & Functions

Freezing Protection: Glycol disrupts water’s crystalline structure to keep the coolant liquid in sub-zero temperatures.

Boiling Prevention: It raises the boiling threshold to stop the fluid from vaporising under high engine heat.

Cavitation Reduction: It minimizes the formation of vapor bubbles, protecting water pump impellers from erosion.

Viscosity Variance: Glycol is thicker than water, requiring a balanced mix (typically 50/50) to maintain optimal flow.

Chemical Base: It must be paired with additive packages to prevent natural acid formation from damaging metal components

Always 奔驰pumps?

With the MCF website as background, think you can open MCF barber if allowed to.😄

PG is mostly found in e-liquids. [in short, the vape liquid]
