Aoa friends
So i have an alto vxr
Its radiator coolant level used to decrease and that used to transfer in reservoir bottle.
Asked the mechanic, changed 2 caps.
But @Xulfiqar bhai taught me coolant going in reservoir tank is normal.
So my bottle was not airtight, changed the bottle. With a genuine one. Still it not air tight, n when the car is hot, Coolant expands, Coolant leaks from the bottle cap sides.
So i want to ask what can be done to make sure its airtight?
Can i use another Japanese cars bottle( which don't leak) with a little alterations in my bottle holder?
