Just wonder if this is normal?

[yuisaka]

Ive bought and using Clean Team XTREME-60 Radiator Coolant from Big W last couple weeks and its run out so fast and remind me the engine's temperature always high so I refilled with Autobarn coolant(I couldn't remerber the brand but its red colour around $45 with 50/50 mixed) but today I check the coolant,it runs out almost half a bottle of 5L coolant again.
I didn't clean the old coolant just filled amost a bottle coolant mix with old one.So is this normal because I didn't refill 10L coolant to new one or it is something wrong with my car?

Take your car to a radiator place asap.
Never mix different coolants

Something definitely wrong with it.

1/ Your engine leaking water
2/ You have a blown head gasket
3/Take your car to nearest mechanic, before you really blow it..
